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. 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. In order for the device to function in the manner intended, it is also necessary to keep a safety distance of ≥ 20 mm (0.78 inch) with adjacent units while the device is in operation. Depending on the surrounding air temperature and output load delivered by the power supply, the device can be very hot! If the device has to be mounted in any other orientation, please contact info@deltapsu.com for more details. Output De-rating VS.

The power supply shall be mounted on minimum of 4 mounting holes using M4 screw maximum 5 mm (0.20 inch) length (Refer to Fig. 4). This is to maintain a safety distance between the screw and internal components. Base Mounting: Fig. 2 and Fig. 3 show the mounting hole locations for power supply assembly onto a metal mounting surface. The power supply shall be mounted on minimum of 4 mounting holes using M4 screw maximum 4 mm (0.16 inch) length (Refer to Fig. 4). Connector This surface belongs to customer’s end system or panel where the power supply is mounted. Base Mounting (Horizontal) Base Mounting (Vertical) Fig. 2 • • Side Mounting (Horizontal) Mounting Orientation Use flexible cable (stranded or solid) of AWG No. 22-12. The input/output connectors’ allowable current is 23 A max per pin. User should calculate and select the suitable wire specification (type/quantity/diameter) according to actual output current. The torque at the connector shall not exceed 13 Kgf.cm (11.23 lbf.in). The insulation stripping length should not exceed 0.275” or 7 mm. Recommended mounting torque of the product and its mounting accessories is 9~12 Kgf.cm (7.81~10.42 lbf.in). Safety Distance D1 = 4mm Min. D2 = 20mm Min. Fig. 3 Mounting Hole Locations and the Safety Distance For safety reasons, please ensure the mounted device is kept at ≥ 4 mm (0.16 inch) safety distance at all sides from other components and equipments. In addition, to ensure sufficient convection cooling, always maintain a distance of ≥ 20 mm (0.79 inch) from fan ventilated surfaces while the device is in operation. Please insert an insulation sheet between the system and product, if the safety distance is < 4 mm (0.16 inch).   Fig. 4 9 Only use M4 screw ≤ 5 mm (0.20 inch) through the base mounting holes at Ⓐ. This is to keep a safe distance between the screw and internal components. Only use M4 screw ≤ 4 mm (0.16 inch) through the base mounting holes at Ⓑ.

If user’s mounting orientation is not according to the recommended mounting orientations, please consult Delta for further information. The device is not recommended to be placed on low thermal conductive surface. For example, plastics. The enclosure of the device can become very hot depending on the ambient temperature and load of the power supply. Do not touch the device while it is in operation or immediately after power is turned OFF. Risk of burning! Do not touch the terminals while power is being supplied. Risk of electric shock. Prevent any foreign metal, particles or conductors from entering the device through the openings during installation. It may cause: - Electric shock; Safety Hazard; Fire; Product failure. Warning: When connecting the device, secure Earth connection before connecting L and N. When disconnecting the device, remove L and N connections before removing the Earth connection. The power supply must be mounted by metal screws onto a grounded metal surface. It is highly recommended that the Earth terminal on the connector be connected to the grounded metal surface.

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. ■ Graph illustrating the Start-up Time, Rise Time, and Hold-up Time Inrush Current Dynamic Response 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. The power supply output voltage will remain within ±5 of its steady state value, when subjected to a dynamic load from 10 to 50% and 50 to 100% of its rated current. 11 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (June 2022, Rev. 08) TECHNICAL DATASHEET PMT Panel Mount Power Supply 48 V 350 W 1 Phase / PMT-48V350W1A□□ Overload & Overcurrent Protections (Auto-Recovery) The power supply’s Overload (OLP) and Overcurrent (OCP) Protections will be activated when output current exceeds 105%~150% of rated load current. In such occurrence, the VO 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. 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 defined on Page 3 under “Protections”. Power supply will latch, and require removal/re-application of input AC voltage in order to restart. The power supply should be latch. Over Temperature Protection (Auto-Recovery) It is not recommended to prolong the duration of IO when it is 105%~150%, since it may cause damage to the PSU. Short Circuit Protection (Auto-Recovery) 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. 12 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, the power supply will run into OTP when the operating temperature is beyond what is recommended 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. All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (June 2022, Rev. 08) TECHNICAL DATASHEET PMT Panel Mount Power Supply 48 V 350 W 1 Phase / PMT-48V350W1A□□ Operating Mode  Redundancy 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 0.45~0.50 V for these 24 V 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. In order to set the output voltage, individually connect each power supply to 50% of rated load at any line voltage from 85-264 Vac, and set the PSU 1 and PSU 2 output voltage. Step 2. Connect the power supply units PSU 1 and PSU 2 to Vin 1 & Vin 2, respectively, of the DRR-20N (or 20 A) module shown on the right of above diagram. Fig. 5 Redundant Operation Connection 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). *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 25 mV 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.
