Datasheet
AC-DC Single Output Power Module
## **PFHC (AC-DC Conversion) and DC-DC Conversion Integrated in One Package.**
## 2-in-1 Design Concept
One module now contains the functions previously only obtainable by combining a front-end module with a high voltage input DC-DC converter. The product is made using a wide range input AC-DC front end function (harmonic current control and power factor correction) and DC-DC back-end (voltage conversion and isolation) in 1 package).

## **6 Over Current Protection (OCP)**
This module is equipped with OCP function. Constant current limiting with automatic recovery for PFE500F Series. Output will automatically recover when short circuit or overload condition is released.
Constant current limiting with delay shutdown for PFE1000F Series. Output will be shutdown when output about under 70 % by short circuit or overload condition that continue about 0.5s. When the shutdown function activates, first cut off input line and verify that boost voltage has dropped down to 20V or less. Then, recover output by recycling input line. In other method, reset to ON/OFF control. OCP value is fixed and cannot be adjusted externally.
Note that continuous short circuit or overload condition more than 30s, might result in power module damage.
## **7 Over Voltage Protection (OVP)**
This module is equipped with OVP function. This value is set between 125% to 145% of nominal output voltage. When the OVP function activates, first cut off input line and verify that boost voltage has dropped down to 20V or less. Then, recover output by recycling input line. In other method, reset to ON/OFF control. OVP value is fixed and cannot be set externally.
## **8 Over Temperature Protection (OTP)**
This module is equipped with OTP function. This function activates and shuts down the output when ambient temperature or internal temperature abnormal rises. OTP activates at following baseplate temperature.
PFE500F-12 : 90 to 115 deg C PFE500F-28, 48 : 105 to 130 deg C PFE1000F-* : 105 to 130 deg C
When OTP function operates, output can be recovered by cooling down the baseplate sufficiently and letting the boost voltage drop down to 20V or less before recycling the input line. In other method, reset to ON/OFF control.
## **9 Remote Sensing (+S, -S terminals)**
This module has remote sensing terminals to compensate for voltage line drop from the output terminals to the output load. When remote sensing is not required, (local sensing) short +S to +V and -S to -V terminals respectively.
Note that line drop (voltage drop due to wiring ) compensation voltage range must be such that the output voltage is within the output voltage adjustment range and that the voltage between -V and -S must be within 0.5V.
Consider power loss due to line drop and use power module within the maximum allowable output power. Reduce the effect of noise to the remote sensing line by using a shield line, a twist pair, or a parallel pattern, etc. When remote sensing line is long, add the electrolytic capacitor as shown in Fig 9-1.

## **14 I.O.G signal (IOG terminal)**
Normal or abnormal operation of the power module can be monitored by using the IOG terminal. Output of this signal monitor is located at secondary side (output side) and is an open collector output.
This signal is LOW when inverter is normally operating and HIGH when inverter stops or when inverter is operating abnormally. (maximum sink current is 5mA, maximum applied voltage is 35V)
Ground for the IOG terminal is the COM terminal. Also note that IOG becomes unstable for following conditions:
･Operation of Over Current Protection (OCP) ･Light load conditions at parallel operation ･Dynamic load operation
## **15Auxiliary power supply for external circuits (AUX terminal)**
For AUX terminal, output voltage value is within 10 ～ 14VDC range, maximum output current is 20mA. Ground for the AUX terminal is COM terminal.
Avoid short circuit of AUX terminal with other terminals as this would lead to power module damage.
## **16 Operating Temperature Range**

## **21 Withstand Voltage**
This module is designed to withstand applied voltage 2.5kVAC between input and baseplate, 3kVAC between input and output for a duration of 1 minute. When doing this test during incoming inspection, set the current limit of test equipment to 20mA.
This module is designed to withstand applied voltage 500VDC between output and baseplate for 1 minute. When doing this test during incoming inspection, be sure to apply DC voltage only. Avoid applying AC voltage during this test because this will damage the module.
Refrain from injecting high test voltage suddenly. Be sure to gradually increase the applied voltage during testing and gradually reduce the voltage after the test.
Especially, when using timer switch of the test equipment, impulse voltage which is higher than the applied set voltage, is generated when the timer switch is cut off. This causes damage to the power module. Connect each terminal according to the circuit diagram shown below.
For basic connection shown in Fig. 1-1, do the same terminal connections.

Connect C13 within 50mm from the output terminals ＋V and －V of the power module to stabilize operation. Note that the output ripple and line turn off characteristics of the power module might be affected by the ESR and ESL of the electrolytic capacitor.
Also, note that output ripple voltage may vary depending on the wiring pattern of the printed circuit board.
Sudden change in output voltage due to sudden load change or sudden input voltage change can be reduced by increasing external output capacitor value.
## **Recommended Voltage Rating：100VDC**
- Note）1. Use low-impedance electrolytic capacitors with excellent temperature characteristics.
- （Nichicon PM Series or equivalent）
2. For module operation at ambient temperature －20 deg C or less, output ripple voltage might be affected by ESR characteristics of the electrolytic capacitors. Increase the capacitor values shown below.
- **C14, C16: 100V 220μF x 2 parallel**
- **（Ambient Temperature<－20 deg C）**
3. Take note of the maximum allowable ripple current of the electrolytic capacitor used. Especially, for sudden load current changes, verify actual ripple current and make sure that allowable maximum ripple current is not be exceeded.
## ● Selection Method of External Bulk Capacitor for
## Boost Voltage
Boost voltage bulk capacitor is determined by boost voltage ripple voltage, ripple current and hold-up time.
Select capacitor value such that boost voltage ripple voltage does not exceed 15Vp-p.
- Note） When ambient temperature is －20 deg C or less, Boost voltage might increase due to ESR characteristics. Therefore, verify above characteristics by actual evaluation.
For output hold-up time, refer to separate document "PFE700S Series Evaluation Data" and use appropriate capacitor up to 1,200uF maximum. (It is recommended that verification should be done through actual evaluation).
For allowable ripple current value, refer to Fig.1-2 and select a capacitor with higher ripple current rating.
## TFR1：10 to 100 ohm
By connecting thermal fuse resistor across R and ＋BC terminals as shown in Fig.1-1, in-rush current during line throw-in can be suppressed. Failures due to in-rush current such as melting of external fuse, welding of relay or switch connecting joints or shutdown of No-Fuse Breakers (NFB) might occur. Therefore, be sure to connect this external thermal fuse resistor.
Note that this module will not operate without this external resistor.
## ● Selection Method of External Resistor
- （1）Calculating Resistance Value for TFR1 Resistance can be calculated by the formula below.
- Vin
- R＝ ~~（~~ Ω）（Formula 1-2） lrush
- R： Resistance Value for External TFR1 Vin： Input Voltage converted to DC value
- ＝ Input Voltage（rms）×√‾2
- Irush：Input surge current value
- （2）Required Surge Current Rating
- Sufficient surge current withstand capability is required for external TFR1. Required surge current rating can be selected by l2t. (Current squared multiplied by time) 2
- l2t＝[ Co×Vin] ~~（~~ A2s）（Formula 1-3） 2×R
- I2t： Current-squared multiplied by time Co： Boost Voltage Bulk Capacitance Vin：Input Voltage converted to DC value ＝ Input Voltage（rms）×√‾2
- R： Resistance Value for External TFR1
## **2 Maximum Ripple and Noise**
This value is measured according to the description below in accordance with JEITA-9131A (Section 7.12 and Section 7.13).
In the basic connection shown in Fig.1-1, additional connection shown in Fig.2-1 is done for measurement. Capacitor (ceramic capacitor 2.2μF and electrolytic capacitor: 220μF) must be connected within 50mm from the output terminals. Then, connect coaxial cable with JEITA attachment across the ceramic capacitor electrodes. Use 100MHz bandwidth oscilloscope or equivalent.
Also, note that output ripple voltage and output spike noise may vary depending on the wiring pattern of the printed circuit board.
In general, output ripple voltage and output spike noise can be reduced by increasing external capacitor value.
