Power supply components may degrade, or be damaged, when the power supply is continuously used outside the shaded region, refer to the graph shown in Fig. 1. 2. If the output capacity is not reduced when the surrounding air temperature exceeds its specification as defined on Page 3 under “Environment”, the device will run into Over Temperature Protection. When activated, the output voltage will go into bouncing mode and will recover when the surrounding air temperature is lowered or the load is reduced as far as necessary to keep the device in working condition. 3. In order for the device to function in the manner intended, it is also necessary to keep a safety distance as recommended in the safety instructions while the device is in operation. 4. Depending on the surrounding air temperature and output load delivered by the power supply, the device can be very hot! - **Fig. 1 De-rating for Vertical Mounting Orientation** -10°C to -20°C de-rate power by 2%/°C > 40°C de-rate power by 1.67% / °C @ 115Vac 5.

**----- End of picture text -----**
## **Fig. 2.1 Mounting** Snap on the DIN rail as shown in Fig. 2.1: 1. Tilt the unit upwards and insert it onto the DIN rail. 2. Push downwards until stopped. 3. Press against the bottom front side for locking. ## **Fig. 2.2 Dismounting** To uninstall, pull or slide down the latch with screw driver as shown in Fig. 2.2. Then slide the power supply unit (PSU) in the opposite direction, release the latch and pull out the power supply unit (PSU) from the rail. 4. Shake the unit slightly to ensure that it is secured. In accordance to EN 60950 / UL 60950 and EN 62368 / UL 62368, flexible cables require ferrules. Use appropriate copper cables designed to sustain operating temperature of at least 60°C / 75°C or more to fulfill UL requirements. All parameters are specified at 25°C ambient and AC input unless otherwise indicated. **www.DeltaPSU.com (December 2020, Rev. 04)** 10 **TECHINCAL DATASHEET** **LYTE DIN Rail Power Supply** 48V 120W 1 Phase / DRL-48V120W1A □ ## Safety Instructions - **Vertical Mounting** - - ALWAYS switch mains of input power OFF before connecting and disconnecting the input voltage to the unit. If mains are not turned OFF, there is risk of explosion / severe damage. - **To guarantee sufficient convection cooling, keep a distance of 50mm (1.97 inch) above and 18cm (7.09 inch) below the device as well as a lateral distance of 10mm (0.39 inch) to other units.** - Note that the enclosure of the device can become very hot depending on the surrounding air temperature and load of the power supply. Risk of burns! - - - - - The main power must be turned off before connecting or disconnecting wires to the terminals. - DO NOT insert any objects into the unit. Hazardous voltages may be present for up to 5 minutes after the input mains voltage is disconnected. Do not touch the unit during this time. - The power supplies are built in units and must be installed in a cabinet or room (condensation free environment and indoor location) that is relatively free of conductive contaminants. All parameters are specified at 25°C ambient and AC input unless otherwise indicated. **www.DeltaPSU.com (December 2020, Rev. 04)** 11 **TECHINCAL DATASHEET** ## **LYTE DIN Rail Power Supply** 48V 120W 1 Phase / DRL-48V120W1A □ ## **Functions** - **Graph illustrating the Start-up Time, Rise Time, and Hold-up Time** ## Start-up Time The time required for the output voltage to reach 90% of its final steady state set value, after the input voltage is applied. ## Rise Time The time required for the output voltage to change from 10% to 90% of its final steady state set value. ## Hold-up Time Time between the collapse of the AC input voltage, and the output falling to 95% of its steady state set value. ## Inrush Current Inrush current is the peak, instantaneous, input current measured and, occurs when the input voltage is first applied. For AC input voltages, the maximum peak value of inrush current will occur during the first half cycle of the applied AC voltage. This peak value decreases exponentially during subsequent cycles of AC voltage. ## Dynamic Response The power supply output voltage will remains within ±10% of its steady state value, when subjected to a dynamic load from 0% to 100% of its rated current. - **50% duty cycle / 5Hz to 100Hz** All parameters are specified at 25°C ambient and AC input unless otherwise indicated. **www.DeltaPSU.com (December 2020, Rev. 04)** 12 **TECHINCAL DATASHEET** ## **LYTE DIN Rail Power Supply** 48V 120W 1 Phase / DRL-48V120W1A □ ## Overload & Overcurrent Protections (Continuous Current) The power supply’s Overload (OLP) and Overcurrent (OCP) Protections will be activated when output current is 105~150% of IO (Max load). Upon such an occurrence, the VO (output voltage) will start to droop. Once the power supply has reached its maximum power limit, the protection will be activated; and, the power supply will operate in continuous current. The power supply will recover once the cause of OLP or OCP is removed, and IO (output current) is back within the specified range. ## Overvoltage Protection (Latch Mode) The power supply’s overvoltage circuit will be activated when its internal feedback circuit fails. The output voltage shall not exceed its specifications as described in “Protections” section. Power supply will latch off, and require removal/re-application of input AC voltage in order to restart. ## **The power supply should be latch.** ## Over Temperature Protection (Latch Mode) ## Short Circuit Protection (Auto-Recovery) The power supply’s output Short Circuit Protection function also provides protection against short circuits. When a short circuit is applied, the output current will operate in “Hiccup mode”. The power supply will return to normal operation after the short circuit is removed. As described in load de-rating section, the power supply also has Over Temperature Protection (OTP). In the event of a higher operating temperature at 100% load; or, when the operating temperature is beyond what is recommended in the de-rating graph, the OTP circuit will be activated. When activated, power supply will latch off, until the surrounding air temperature drops to its normal operating temperature or the load is reduced as recommended in the de-rating graph. Removal/re-application of input AC voltage will then be required in order to restart. All parameters are specified at 25°C ambient and AC input unless otherwise indicated. **www.DeltaPSU.com (December 2020, Rev. 04)** 13 **TECHINCAL DATASHEET** ## **LYTE DIN Rail Power Supply** 48V 120W 1 Phase / DRL-48V120W1A □ ## Operating Mode ##  **Redundant Operation** In order to ensure proper redundant operation for the power supply units (PSUs), the output voltage difference between the two units must be kept at 0.9~1.0V for these 48V supplies. Follow simple steps given below to set them up for the redundant operation: ## **Step 1.** Measure output voltage of PSU 1 and PSU 2. If PSU 1 is the master unit, then VO of PSU 1 must be higher than PSU 2. ## **Step 2.** Connect the power supply units PSU 1 and PSU 2 to Vin 1 & Vin 2, respectively, of the DRR-20N (or 20A) module shown on the right of above diagram. ## **Step 3.** Connect the system load to Vout. Please note that output voltage Vout from DRR module will be = VO (output voltage of power supply) – Vdrop* (in DRR module). **The Signal GND in the DRR module is for the built-in LED and DC OK signals. The Output GND terminals from the two PSU’s do not need to be connected to the Signal GND terminal. ## **Fig. 3 Redundant Operation Connection Diagram** *Vdrop will vary from 0.60V to 0.90V (Typical 0.65V) depending on the load current and surrounding air temperature. ##  **Parallel Operation** The power supply units (PSUs) can also be used for parallel operation in order to increase the output power. The difference in output voltage between the two units must be kept to within 25mV of each other. This difference must be verified with the same output load connected independently to each unit. Parameters such as EMI, inrush current, leakage current, PARD, start up time will be different from those on the datasheet, when two units are connected in parallel. The user will need to verify that any differences will still allow the two power supplies connected in parallel will work properly in their product/application. **Fig. 4 Parallel Operation Connection Diagram** All parameters are specified at 25°C ambient and AC input unless otherwise indicated. **www.DeltaPSU.com (December 2020, Rev. 04)** 14 **TECHINCAL DATASHEET** ## **LYTE DIN Rail Power Supply** 48V 120W 1 Phase / DRL-48V120W1A □ ## **Others** ## Conformal Coating ## **The Protective Coating Technology** Delta Electronics Group has designed the perfect dipping technique which penetrates everywhere including under device, and prevents leakage. The conformal coating dipping can be applied to PCBAs or circuit board. The coating preserves the performance of precision electronic primarily by preventing ionizable contaminants such as salt from reaching circuit nodes, where the material slumps around sharp edges. This can be a problem especially in highly conversing atmosphere. ## PFC – Norm EN 61000-3-2 ## **Line Current Harmonic content** Typically, the input current waveform is not sinusoidal due to the periodical peak charging of the input capacitor. In industrial environment, complying with EN 61000-3-2 is only necessary under special conditions. Complying to this standard can have some technical drawbacks, such as lower efficiency as well as some commercial aspects such as higher purchasing costs. Frequently, the user does not profit from fulfilling this standard, therefore, it is important to know whether it is mandatory to meet this standard for a specific application. ## Attention Delta provides all information in the datasheets on an “AS IS” basis and does not offer any kind of warranty through the information for using the product.
