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 ).
