Features include full power factor correction, good hold-up time, high efficiency and reliability, low output noise, and excellent dynamic response to load/line changes. The converters are protected against surges and transients occurring at the source lines. Input over- and undervoltage lockout circuitry disables the outputs, when the input voltage is outside of the specified range. Input inrush current limitation is included for preventing circuit breakers and fuses from tripping at switch-on. All outputs are overload, open- and short-circuit proof, and protected by a built-in suppressor diode. The outputs can be inhibited by a logic signal applied to connector pin 18. If the inhibit function is not used, pin 18 must be connected with pin 14 to enable the outputs. LED indicators display the status of the converter and allow visual monitoring of the system at any time. Full input to output, input to case, output to case and output to output isolation is provided. The converters are designed and built according to the international safety standards IEC/EN 60950-1 2[nd] Ed. They have been approved by safety agencies. The case design allows operation at nominal load up to 71 °C in a free air ambient temperature. If forced cooling is provided, the ambient temperature may exceed 71 °C, but the case temperature must remain below 95 °C under all conditions. However, higher output power up to 280 W is possible depending on environmental conditions and converter model. **Table of Contents** Page **==> picture [233 x 63] intentionally omitted <==** **----- Start of picture text -----**<br> ||| |---|---| |Description....................................................................... 1| |Model Selection ............................................................... 2| |Functional Description..................................................... 4| |Electrical Input Data ........................................................ 5| |Electrical Output Data|..................................................... 8| |Auxiliary Functions|........................................................ 13| **----- End of picture text -----**<br> **==> picture [238 x 76] intentionally omitted <==** **----- Start of picture text -----**<br> ||| |---|---| |Page| |Electromagnetic Compatibility (EMC) ........................... 16| |Environmental Conditions|............................................. 17| |Mechanical Data ............................................................ 18| |Safety and Installation Instructions ............................... 20| |Description of Options ................................................... 22| |Accessories|................................................................... 27| **----- End of picture text -----**<br> **Copyright © 201 8 , Bel Power Solutions Inc.

This step-up converter provides a sinusoidal input current (IEC/EN 61000-3-2, class D equipment) and charges the bulk capacitor _C_ b to approx. 370 VDC. This capacitor sources a single-transistor forward converter and provides the power during the hold-up time. The second output of double output models is tracking the main output, but has its own current limiting circuit. If the main output voltage drops due to current limitation, the second output voltage will fall as well and vice versa. A separate auxiliary converter generates the supply voltages for all primary and secondary control circuits and options. The main transformer exhibits a separate secondary winding for each output. Each generated voltage is rectified and smoothed by the power choke and the output filter.

Do not check the overvoltage lockout function! If _V_ i is below _V_ i min, but above the undervoltage lockout level, the output voltage may be below the value specified in the tables _Electrical Output Data._ ## **Inrush Current Limitation** The models without option E incorporate an NTC resistor in the input circuitry, which at initial turn-on reduces the peak inrush current value by a factor of 5 to 10 to protect connectors and switching devices against damage. Subsequent switch-on cycles within short periods will cause an increase of the peak inrush current value due to the warming-up of the NTC resistor. The inrush current peak value (initial switch-on cycle) can be determined by following calculation: **==> picture [109 x 26] intentionally omitted <==** **==> picture [218 x 50] intentionally omitted <==** **----- Start of picture text -----**<br> 04001b<br>R s ext I inr p R i R NTC<br>+<br>∼ V i C b<br>**----- End of picture text -----**<br> _Fig. 3 Equivalent circuit diagram for input impedance._ _**MELCHER**_ Page 5 of 28 BCD20001-G Rev AF1, 17-Apr-2018 _The Power Partners._ _**K Series with PFC Data Sheet 150**_ **–** _**280 Watt AC-DC Converters**_ ~~as~~ **==> picture [192 x 332] intentionally omitted <==** **----- Start of picture text -----**<br> I inr [A]<br>100 04054a<br>es<br>a LKP<br>LK<br>Wee<br>ical<br>50 WO<br>T IRE J<br>ES<br>—E = SS<br>SS<br>0 a<br>0.1 0.5 1 ms<br>Theoretical worst case input inrush current versus<br>i = 255 V, R ext = 0 for models without<br>04002a<br>2 a<br>LKP<br>Ce<br>1<br>ee LK<br>nd<br>0 a<br>50 100 150 200 250 VAC<br>l i [A]<br>**----- End of picture text -----**<br> _Fig. 4_ _Theoretical worst case input inrush current versus time at V_ i _= 255 V, R_ ext _= 0 for models without option E_ _Fig. 5 Input current versus input voltage at I_ o nom ## **Power Factor and Harmonics** Power factor correction is achieved by controlling the input current waveform synchronously with the input voltage waveform.

However, the relationship between _T_ A and _T_ C depends heavily on the conditions of operation and integration into a system. The thermal conditions are influenced by input voltage, output current, airflow, and temperature of surrounding components and surfaces. _T_ A max is therefore, contrary to _T_ C max, an indicative value only. **Caution:** The installer must ensure that under all operating conditions _T_ C remains within the limits stated in the table: _Temperature specifications._ **Notes:** Sufficient forced cooling or an additional heat sink (applied to -7 or -9) models allows _T_ A to be higher than 71 °C (e.g., 85 °C), if _T_ C max is not exceeded. Details are specified in fig. 12, including -5 and -6 models. **==> picture [193 x 133] intentionally omitted <==** **----- Start of picture text -----**<br> I o/ I o nom<br>convection cooling forced cooling<br>1.0 Z<br>0.8<br>-5 -6 -7<br>0.6<br>T C max<br>0.4 -5 -6 -7<br>TINAR<br>0.2<br>TERA<br>0 NNN T A<br>50 60 70 80 90 100 °C<br>05143b<br>**----- End of picture text -----**<br> _Fig. 12_ _Output current derating versus temperature for -5, -6, and -9 (or -7) models._ ## **Output Protection** Each output is protected by a suppressor diode against overvoltage, which could occur due to a failure of the control circuit. In such a case, the suppressor diode becomes a short circuit. The suppressor diodes may smooth short overvoltages resulting from dynamic load changes, but they are not designed to withstand externally applied overvoltages. A short circuit at any of the two outputs will cause a shutdown of the other output. A red LED indicates any overload condition. **Note:** _V_ o BR is specified in _Electrical Output Data_ . If this voltage is exceeded, the suppressor diode generates losses and may become a short circuit. ## **Parallel or Series Connection of Converters** Single- or double-output models with equal output voltage can be connected in parallel without any precautions using option T (current sharing). If the T pins are interconnected, all converters share the output current equally. Single-output models and/or main and second outputs of double-output models can be connected in series with any other (similar) output. ## **Notes:** - Parallel connection of double-output models should always include both, main and second output to maintain good regulation. - Not more than 5 converters should be connected in parallel. - Series connection of second outputs without involving their main outputs should be avoided, as regulation may be poor. - Series connection of outputs totalizing more than 36 V nominal voltage need additional measures to limit the output to SELV (Safe Extra Low Voltage). - The maximum output current is limited by the output with the lowest current limitation, if several outputs are connected in series. ## **Thermal Protection** A temperature sensor generates an internal inhibit signal, which disables the outputs, when the case temperature exceeds _T_ C max. The outputs automatically recover, when the temperature drops below this limit. Continuous operation under simultaneous extreme worstcase conditions of the following three parameters should be avoided: Minimum input voltage, maximum output power, and maximum temperature.

If both outputs are loaded with more than 10% of _I_ o nom, the deviation of _V_ o2 remains within ±5% of _V_ o1. The following 3 figures show the regulation with varying load distribution. Two outputs of a double-output model connected in parallel behave like the output of a single-output model. **Note:** If output 2 is not used, we recommend connecting it in parallel with output 1.

Incorrectly connected sense lines may activate the overvoltage protection resulting in a permanent short-circuit of the output. This feature allows for compensation of voltage drops across the connector contacts and if necessary, across the load lines. We recommend connecting the sense lines directly at the female connector. To ensure correct operation, both sense lines (S+, S–) should be connected to their respective power outputs (Vo+ and Vo– ), and the voltage difference between any sense line and its respective power output (as measured on the connector) should not exceed the following values: _Table 9: Maximum voltage compensation allowed using sense lines_ |_Table 9: Maximum voltage compensation allowed using_<br>_sense lines_|_Table 9: Maximum voltage compensation allowed using_|_Table 9: Maximum voltage compensation allowed using_| |---|---|---| |**Output**<br>**voltage**|**Total voltage difference**<br>**between sense lines and**<br>**their respective outputs**|**Voltage difference**<br>**between**<br>**Vo– and S–**| |5.1 V|<0.5 V|<0.25 V| |12 V, 15 V, 24 V|<1.0 V|<0.25 V| **Note:** If the output voltages are increased above _V_ o nom via R-input control, option P setting, remote sensing, or option T, the output currents must be reduced accordingly, so that _P_ o nom is not exceeded. ## **Programmable Output Voltage** (R-Function) As a standard feature, the converters offer an adjustable output voltage, identified by letter R in the type designation. The control input R (pin 16) accepts either a control voltage _V_ ext or a resistor _R_ ext to adjust the desired output voltage. When input R is not connected, the output voltage is set to _V_ o nom. a) Adjustment by means of an external control voltage _V_ ext between pin 16 (R) and pin 14: The control voltage range is 0 – 2.75 VDC and allows an output voltage adjustment in the range of approximately 0 – 110% _V_ o nom. **==> picture [85 x 22] intentionally omitted <==** b) Adjustment by means of an external resistor: Depending upon the value of the required output voltage the resistor shall be connected **either:** Between pin 16 and pin 14 ( _V_ o < _V_ o nom) to achieve an output voltage adjustment range of approximately 0 – 100% _V_ o nom. **or:** Between pin 16 and pin 12 ( _V_ o > _V_ o nom) to achieve an output voltage adjustment range of 100 – 110% _V_ o nom. ## **Warning:** - _V_ ext shall never exceed 2.75 V. - The value of _R_ 'ext shall never be less than the lowest value as indicated in table _R_ 'ext (for _V_ o > _V_ o nom) to prevent the converter from damage! _**MELCHER**_ Page 13 of 28 BCD20001-G Rev AF1, 17-Apr-2018 _The Power Partners._ _**K Series with PFC Data Sheet 150**_ **–** _**280 Watt AC-DC Converters**_ ## **Notes** : - The R-Function excludes option P (output voltage adjustment by potentiometer). - If the output voltages are increased above _V_ o nom via R-input control, option P setting, remote sensing, or option T, the output currents should be reduced, so that _P_ o nom is not exceeded. - With double-output models the second output follows the value of the controlled main output. - In case of parallel connection the output voltages should be individually set within a tolerance of 1 – 2%. **==> picture [143 x 156] intentionally omitted <==** **----- Start of picture text -----**<br> 06003a<br>N~ yo Vo1+<br>R +<br>16<br>S– V ext<br>14<br>L~ Vo1–<br>N~ Vo1+<br>S+<br>12 R' ext<br>POT R<br>16<br>S–<br>14 R ext<br>L~ Vo1–<br>**----- End of picture text -----**<br> _Fig. 21 Output voltage control for single-output models_ **==> picture [239 x 157] intentionally omitted <==** **----- Start of picture text -----**<br> Vo2+ 4 06004a +<br>Vo2+ 6<br>Vo2– 8 24 V<br>V o1 30 V C o<br>Vo2– 10 48 V<br>Vo1+ 12<br>Vo1– 14 –<br>R ext R' ext<br>R 16<br>—e ee<br>Fig. 22<br>Double-output models:<br>**----- End of picture text -----**<br> _Wiring of the R-input for output voltages 24 V, 30 V, or 48 V with both outputs in series.

Not for new designs, use option K !_ These converters are components, intended exclusively for inclusion within other equipment by an industrial assembly operation or by professional installers. Installation must strictly follow the national safety regulations in compliance with the enclosure, mounting, creepage distances, clearances, casualty, markings, and segregation requirements of the enduse application. Connection to the system shall be made via the matching H15 female connector H15; see _Accessories._ Other installation methods may not meet the safety requirements. > Pin no. 24 ( © ) is reliably connected with the case. For safety reasons it is essential to connect this pin reliably to protective earth. See _Safety of Operator-Accessible Output Circuits_ . The phase input 30/32 (L~) is connected via a built-in fuse (see _Input Fuse_ and table 4), which is designed to protect in the case of a converter failure. An additional external fuse, suitable for the application, might be necessary in the wiring to the other line input 26/28 (N~) if: - Local requirements demand an individual fuse in each source line _**MELCHER** The Power Partners._ Page 20 of 28 BCD20001-G Rev AF1, 17-Apr-2018 _**K Series with PFC Data Sheet 150**_ **–** _**280 Watt AC-DC Converters**_ - Phase and neutral of the mains are not defined or cannot be assigned to the corresponding terminals (L~ to phase and N~ to neutral). - Neutral and earth impedance is high or undefined All boards of the converters are coated with a protective lacquer. The converters are subject to manufacturing surveillance in accordance with the above mentioned UL standards and ISO 9001:2008. A CB-scheme is available. ## **Notes:** - If the inhibit function is not used, pin no. 18 (i) should be connected to pin no. 14 (S–/Vo1–) to enable the output(s). ## **Protection Degree and Cleaning Liquids** Condition: Female connector fitted to the converter. - Do not open the converters, or warranty will be invalidated. - IP 30: All models except those with option P, and except those with option D or V including a potentiometer. - Due to high current values, the converters provide two internally parallel contacts for certain paths (pins 4/6, 8/10, 26/ 28 and 30/32). It is recommended to use both female contacts in parallel connection order to keep the voltage drop and the temperature of the contacts low. - IP 20: All models fitted with option P, or with option D or V with potentiometer. In order to avoid possible damage, any penetration of cleaning fluids is to be prevented. - If the second output of double-output models is not used, connect it in parallel with the main output. Make sure that there is sufficient airflow available for convection cooling. This should be verified by measuring the case temperature, when the converter is installed and operated in the end-use application; see _Thermal Considerations._ ## **Isolation and Leakage Currents** The electric strength test is performed in the factory as routine test in accordance with EN 50514 and IEC/EN 60950. The company will not honor warranty claims resulting from incorrectly performed electric strength field tests. Ensure that a converter failure (e.g., an internal short-circuit) does not result in a hazardous condition; see also _Safety of Operator-Accessible Output Circuits._ Leakage currents flow due to internal leakage capacitances and Y-capacitors. The current values are proportional to the supply voltage and are specified in the table below. ## **Standards and Approvals** _Table 16: Leakage currents_ The converters are safety-approved to EN/IEC 60950-1 and UL/CSA 60950-1 2[nd] Ed. |_Table 16: Leakage currents_|_Table 16: Leakage currents_||| |---|---|---|---| |**Characteristic**||**Class I**|**Unit**| |Maximum earth<br>leakage current|Permissible according to IEC/EN 60950|3.5|mA| ||Typ. value at 254 V, 50 Hz (LK models)|0.8|| ||Typ. value at 254 V, 50 Hz (LKP models)|0.8|| The converters correspond to Class I equipment and have been evaluated for: - Building-in - Basic insulation between input and case based on 250 VAC, and double or reinforced insulation between input and output(s). ## **Railway Applications and Fire Protection** The converters have been designed by observing the railway standards EN 50155 and EN 50121-4. All boards are coated with a protective lacquer. - Functional insulation between outputs. - Overvoltage category II The converters with version V108 (or later) comply with NF-F16 (I2/F1).

If the output voltages are increased above _V_ o nom via R input via R input control, option P setting, remote sensing, or option T, the output current(s) should be reduced accordingly, so that _P_ o nom is not exceeded. ## **T Current Sharing** This option ensures that the output currents are approximately shared between all parallel-connected converters, hence increasing system reliability. To use this facility, simply interconnect the T pins of all converters and make sure that the reference for the T signal (pin 14: S– or Vo1–), are also connected together.

Any value within the specified range is basically possible, but causes a special type designation in addition to the standard option designations (D0/D9). - 4 _V_ b is the voltage generated by the boost regulator. When _V_ b drops below 355 V, the D signal triggers, and the output(s) will remain powered during nearly the full hold-up time _t_ h. ## **D Undervoltage Monitor** The input and/or output undervoltage monitoring circuit operates independently of the built-in input undervoltage lockout circuit. A logic "low" (self conducting JFET) or "high" signal (NPN output) is generated at the D output (pin 20), when one of the monitored voltages drops below the preselected threshold level _V_ t. This signal is referenced to S– /Vo1–. The D output recovers, when the monitored voltages exceed _V_ t + _V_ h. The threshold level _V_ bi is adjusted in the factory. The threshold level _V_ to is either adjusted by a potentiometer accessible through a hole in the front cover, or adjusted in the factory to a fixed value specified by the customer. _Table 22: JFET output (D0 – D4)_ |**_V_b, ****_V_o1 status**|**D output,****_V_D**| |---|---| |_V_bor_V_o1<_V_t|low, L,_V_D ≤0.4 V at_I_D= 2.5 mA| |_V_band_V_o1>_V_t+_V_h|high, H,_I_D ≤25 µA at_V_D= 5.25 V| ## **NPN output (D5 – DD):** Pin D is internally connected via the collector-emitter path of a NPN transistor to the negative potential of output 1. _V_ D < 0.4 V (logic low) corresponds to a monitored voltage level ( _V_ i and/or _V_ o1) > _V_ t + _V_ h.
