PS 124 • Installation Guide
Introduction
The Extron PS 124 is a high performance, plenum rated (with optional Flexible Conduit Adapter Kit), 12 VDC power supply. The
auto‑switchable 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 inches deep metal enclosure, allowing the PS 124 to take
advantage of a variety of mounting options (see

- Page 1 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 inches deep metal enclosure, allowing the PS 124 to take advantage of a variety of mounting options (see Mounting the PS 124 on page 5).
- Page 2 To identify the shorted output, unplug the outputs one at a time until the LEDs light green. Input Power Apply power to the PS 124 using the supplied IEC power cord or by installing the optional Flexible Conduit Adapter Kit. — Plug the IEC cord into this connector and a 100–240 VAC source.
- Page 3 Output 7 Output 6 Output 5 Figure 3. Application Diagram Connections Input Power — Using the IEC Power Cord Use the included IEC power cord to connect the PS 124 to a 100 VAC to 240 VAC, 50‑60 Hz power source.
- Page 4 The optional Flexible Conduit Adapter Kit provides a convenient means to replace the IEC power cord with conduit when required by local codes. For more information go to www.extron.com. Make certain the PS 124 and all connected devices are turned off and disconnected from the power source before beginning.
- Page 5 If necessary, mount the half‑rack width false front panel (included with the Universal Rack Shelf only) and/or the quarter rack width false front panel (included with the PS 124) to the shelf, using two 4‑40 x 3/16 inch screws in the front holes for each...
- Page 6 Under-desk Mounting In addition to using the PS 124 power supply on a rack or projector, it can also be mounted under furniture (such as a desk) using an under‑desk mounting kit (see under‑desk mounting options at www.extron.com).
