Extron electronic PS 124 Introduction, Front and Rear Panel Features, LED indicators

Introduction

The Extron PS 124 is a high performance, plenum rated (with optional Flexible Conduit kit), 12 VDC power supply. The autoswitchable 100 VAC to 240 VAC input can supply a maximum current of 4 amps for up to eight outputs. Each DC output is on a two-pole captive screw connector, with no per-output current limitation. Two-tone LEDs on the front and rear panels indicate normal operation (green) and overload condition (red).

The rack mountable PS 124 has a 1U high, quarter rack wide, 9" deep metal enclosure, allowing the PS 124 to take advantage of a variety of mounting options.

LED indicators

A	Power status LEDs — These front and rear panel LEDs indicate
	the PS 124 status by lighting as follows:
	• Green when power is applied and current draw is normal
	• Red indicates a current overload condition
	C Continued operation in an overload condition may
	cause premature power supply failure.
	• Unlit when an output is shorted
	N To identify the shorted output, unplug the outputs one at
	a time until the LEDs light green.
