Input Voltage Note 1. 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 >50 °C, 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 of 20mm with adjacent units 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! 5.

Follow the DC power source voltage and current limiting defined in the table below. Built-in Resistor Ri (ohm) Voltage Between RC+ and RC- (V) Input Current (mA) Output ON Output OFF 820 5-12.5 0-0.5 20 Max Notes 1. Remote ON/OFF circuits are isolated from input, output and PE. 2. Please check if the polarity of the wire connector is the same as the external DC source. If not, the power would not turn on and the internal components may be damaged. 3. You do not need an external resistance R O for current limit while the output voltage of external DC source is within the range of 5-12.5V. If the output voltage exceeds 12.5V, please use the following equation for the value of current limit resistance RO. 𝑅𝑂 = 𝑉𝑐𝑐 −(3.5 + 0.006𝑅𝑖) 0.006

PMF Panel Mount Power Supply 24V 320W 1 Phase / PMF-24V320WC□□ All parameters are specified at 25°C ambient unless otherwise indicated. www.DeltaPSU.com (June 2014, Rev. 00) Functions Start-up Time The time required for the output voltage to reach 90% of its 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 set value. Hold-up Time Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time required for the output to reach 95% of its set value, after the input voltage is removed. ■ Graph illustrating the Start-up Time, Rise Time, and Hold-up Time 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 ±5% of its steady state value, when subjected to a dynamic load from 0 to 100% of its rated current.

PMF Panel Mount Power Supply 24V 320W 1 Phase / PMF-24V320WC□□ All parameters are specified at 25°C ambient unless otherwise indicated. www.DeltaPSU.com (June 2014, Rev. 00) Overload & Overcurrent Protections The power supply’s Overload (OLP) and Overcurrent (OCP) Protections will be activated when output current exceeds 105-150% of I O (Max load). In such occurrence, the V O will start to droop and once the power supply has reached its maximum power limit, the protection is activated and the power supply will go into “Hiccup mode” (Auto- Recovery). The power supply will recover once the fault condition of the OLP and OCP is removed and IO is back within the specifications. It is not recommended to prolong the duration of I O when it is <105% but >100%, since it may cause damage to the PSU. Short Circuit Protection The power supply’s output OLP/OCP function also provides protection against short circuits. When a short circuit is applied, the output current will operate in “Hiccup mode”, as shown in the illustration in the OLP/OCP section on this page. The power supply will return to normal operation after the short circuit is removed. Overvoltage Protection The power supply’s overvoltage circuit will be activated when its internal feedback circuit fails. The output voltage shall not exceed its specifications defined on Page 3 under “Protections”. The power supply should be latch. Over Temperature Protection As mentioned above, the power supply also has Over Temperature Protection (OTP). In the event of a higher operating temperature at 100% load, the power supply will run into OTP when the operating temperature is beyond what is recomme nded in the de-rating graph. When activated, the output voltage will go into bouncing mode until the temperature drops to its normal operating temperature as recommended in the de-rating graph.

Follow simple steps given below to verify: Step 1. Measure output voltage of PSU 1 and PSU 2. If PSU 1 is the master unit, then V O of PSU 1 must be higher than PSU 2. In order to set the output voltage, connect the power supply to 50% load and set the PSU 1 and PSU 2 output voltage. Step 2. Connect the right DRR module, 4 0A as per the system requirement to the power supply units PSU 1 and PSU 2 at V in 1 & V in 2 respectively. Step 3. Connect the system load from V out. Please note that output voltage V out from DRR module will be = V O (output voltage of power supply) – Vdrop* (in DRR module).  Parallel Operation + 2.5A + 2.5A = 7.5A) or current sharing, and thus increasing the power supply and system reliability. Though the PMF-24V320WC☐☐ is not designed for current sharing, a good current sharing between two power supplies can be achieved by following simple steps as below (Refer to Fig. 5 for the Connection Diagram). drop will vary from 0.60V to 0.90V (Typical 0.65V) depending on the load current and surrounding air temperature. Fig. 5 Redundancy / Parallel Operation Connection Diagram Step 1. Set output load condition for both supplies at 50% and measure the output voltages. Step 2. Adjust output voltages to the same level or within ±25mV difference. Step 3. Connect PSU 1 and PSU 2 with the DRR -40A module and measure at Vin 1 & Vin 2 to verify the voltage difference. Ensure the voltages are within ±25mV. Step 4. Output voltage from DRR module V out will be = V O (output voltage of power supply) – Vdrop* (in DRR module).

RoHS is the abbreviation f or “Restriction of the use of certain hazardous substances in electrical and electronic equipment”. This product conforms to this standard. 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 st andard for a specific application.
