PS 125 • Installation Guide
Introduction
The Extron PS 125 is a high performance, 60W, 12 VDC power supply. The auto‑switchable
100 VAC to 240 VAC input can supply a maximum current of 5 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 125 has a 1U high, quarter rack wide, 8.5 inches deep metal enclosure, allowing the PS 125 to take
