Ruijie-Reyee RG-NIS-PA240-48 AC/DC 240W DIN-Rail Power Supply Module for Industrial Switch

The Ruijie-Reyee RG-NIS-PA240-48 is a DC power supply module that provides DC power input to one RG-NIS3100-8GT2SFP-HP or one RG-NIS3100-8GT4SFP-HP Industrial Switch. It supplies 48V/5A rated voltage to the system. The front panel has a three-pin power connector at the bottom for connecting a standard 10A power cord. The ADJ port is for outputs adjustable voltage from 48V 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.
