Delta PMC-48V600W1B Series Instruction Manual

Instruction Manual
1. Safety Instructions
• To ensure sufficient convection cooling, always maintain a safety distance of ≥ 50mm from all ventilated
surfaces while the device is in operation.
• The device is not recommended to be placed on low thermal conductive surface, for example,
plastics.
• Note that 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 to enter the device through the openings during
installation. It can 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.

3. Installation of the Device
The unit is protected with internal fuse (not replaceable) at L pin and it has been tested
and approved on 20A (UL) and 16A (IEC) branch circuits without additional protection device.
Refer to Fig. 2.:
Ⓐ Mounting holes for power supply assembly onto the mounting surface. The power supply shall
be mounted on minimum 4 mounting holes using M4 screw.
Ⓑ Input / Output connector
Ⓒ This surface belongs to customer's system or panel where the power supply is mounted.
• Use Flexible cable (strand or solid) of AWG No. 14-12. The torque at the Input connector shall
not exceed 11.98Kgf.cm. The torque at the Output connector shall not exceed 16.59Kgf.cm.
The insulation stripping length should not exceed 0.275" or 7mm (Refer to Fig. 3).
4. Installation of Mounting Accessories
Refer to Fig. 4.:
• Only use M4 screw ≤ 6mm through the base mounting holes. This is to keep a safe
distance between the screw and internal components.
• Recommended mounting torque for tightening: 4〜8Kgf.cm.
5. Input Voltage Derating Curve
• Output derating is required at 85-115Vac (Refer to Fig. 5).
