Ruijie-Reyee RG-NIS-PA120-48 AC/DC 120W DIN-Rail Power Supply Module for Industrial Switch

The Ruijie-Reyee RG-NIS-PA120-48 is a DC power supply module that provides DC power input to one RG-NIS3100-4GT2SFP-HP Industrial Switch. It supplies 48 V/2.5 A rated voltage to the system. The front panel has a three-pin power connector at the bottom for connecting a standard 10 A power cord. The ADJ port is for outputs adjustable voltage from 47V to 53V based on adjustable resistance. DC OK Relay Contact: Rated: 30V at 1A, resistive load. The relay contacts are normally “ON” (closed) when the output (Vout) is greater than 90% of its rated value.

Working Conditions:

Output power derating:

• Operating temperature derating:
  –40ºC to –25ºC (–40°F to –13°F) Value: 3.34%/℃
  55ºC to 70ºC (131°F to 158°F), 85V AC to 164V AC input, Value: 2.0%/℃
  60ºC to 70ºC (140°F to 158°F), 165V AC to 264V AC input, Value: 2.5%/℃

Input voltage derating:

• 85V AC to 100V AC, Value: 0.67%/V AC

Short circuit protection:

• After the short circuit is eliminated, the power supply is restored within 10s
• Hiccup mode:
  - Maintain constant current for 1s and power off for 10s to provide long-term short circuit protection and self-recovery

Overcurrent protection:

• 230 V AC, rated load:
  - Ordinary temperature, high temperature: Value: 105%–200% Io, self-recovery
  - Low temperature: Value: ≥ 105%, full load after derating, self-recovery

Overvoltage protection:

• 48 V:
  - Value: ≤ 60 V (hiccup, self-recovery after an exception is eliminated

Overtemperature protection:

• 230 V AC, 70% load: Start of overtemperature protection, Value: 90ºC (194°F)
• 230 V AC, 70% load: End of overtemperature protection Lowest: Value: 60ºC (140°F)
