Introduction

The Extron PS 123 is a high performance, plenum rated,

DC power supply that accepts a 100 VAC to 240 VAC input and outputs 12 VDC, 3 amp maximum for the total current of the eight outputs. The DC outputs are on two-pole captive screw connectors, with no per-output current limitation. Two-tone LEDs on the front and rear panel indicate normal operation (green) and overload operation (red).

The rack mountable PS 123 has a 1U high, quarter rack wide, 8.5" deep metal enclosure, allowing the PS 123 to take advantage of a variety of mounting options.

Front and Rear Panel Features

All power and output connections are on the rear panel. LEDs show power status on the front and rear of the power supply (figure 1, A).
