Table of Contents, cont’d ii PS 124 12 VDC, 4 Amp Power Supply • Table of Contents
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).
PS 124, cont’d Input Power b -OR- c Apply power to the PS 124 using the supplied IEC power cord (b) or by installing the optional Flexible Conduit Adapter Kit (Extron part #70-228-02) (c). IEC connector/power supply — Plug the IEC cord into this connector and a 100–240 VAC source. Optional conduit adapter plate — The IEC connector and adapter plate can be replaced by this half-inch conduit EMT (Electrical Metallic Tubing) adapter plate, as shown in figure 2.
DC Outputs d DC Output connectors — Connect the power cables from devices that will receive power from the PS 124 to these 3.5 mm captive screw connectors. The PS 124 supports up to eight power supply outputs. For details on limitations and how to wire these captive screw connectors, see “Output power — wiring the DC output connectors,” on page 8. 5 4 3 2 1 RC 5A A MD A L S UT TP OU R WE POV X Extron MDA 5A RCA R 12A MA .
PS 124, cont’d 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. W The circuit breaker used for this connection should be rated 20 amps maximum. Input power — using the Flexible Conduit Adapter Kit The optional Flexible Conduit Adapter Kit, part # 70-228-02, provides a convenient means to replace the IEC power cord with conduit when required by local codes.
UL guidelines The Underwriters Laboratories (UL) guidelines listed below pertain to the installation of the flexible conduit option. • This unit is not to be used beyond its rated voltage range. • This unit must be wired to a UL listed distribution box. N The electrical distribution box is not included with either the PS 124 power supply or the Flexible Conduit Adapter Kit; the installer is responsible for obtaining and installing a UL Listed box.
PS 124, cont’d 3. Remove and retain the six screws that attach the top cover of the PS 124 to the chassis (figure 5). Lift the cover straight up. Remove three screws on each side. 4 12 P/S PPLY U RS 12 C VD 4A WE PO AD LO ER D-OV RE Figure 5 — Removing the top cover 4. Carefully lift the top cover up, taking care not to remove it completely. C 5. Rough handling of the top cover can tear wiring that connects the front panel LED.
7. From the rear panel end, pull the IEC connector (see figure 4) out of the enclosure. 8. From the conduit kit, thread the 18-gauge power wires through the length of the electrical conduit tube. 9. Install the EMT adapter plate (figure 2) into the opening. Use the Phillips head screws removed in step 2 (figure 4) to attach the adapter plate. N 10. If the conduit is attached to the EMT plate, skip step 10.
PS 124, cont’d Output power — wiring the DC output connectors The PS 124 can supply 12 VDC to multiple devices using 3.5 mm, 2-pole captive screw connectors. The combined current draw of the connected devices must not exceed 4 amps. To verify proper polarity before connection to a device, plug in the power supply with no load and check the output polarity with a voltmeter. Remove power before continuing.
Installing the PS 124 There are several optional accessories for mounting the PS 124. They include the following Extron part numbers: • RSU 129 1U 9.5" Deep Universal Rack Shelf (part #60-190-01) • RSB 129 1U 9.5" Deep Basic Rack Shelf (part #60-604-01) • MBU 125 1U Under-Desk Mounting (part #70-077-01) • PMK 350 Low Profile Pole Mount Kit for Multiple Products (part #70-563-03) Additional mounting options may be found on the Extron website at www.extron.
PS 124, cont’d Rack mounting For optional rackQuarterRackStandardShelf mounting, mount up to four PS 124 power supplies on an RSU 129 9.5" 1U Universal Rack Shelf (part #60-190-01) (figure 8) or an RSB 129 9.5" 1U Basic Rack Shelf (part #60-604-01). 1U Universal Rack Shelf 1/2 Rack Width Front False Faceplate 1/4 Rack Width Front False Faceplate Both front false faceplates use 2 screws. (2) 4-40 x 3/16" Screws Use 2 mounting holes on opposite corners. Figure 9 — Rack mounting the PS 124 10 1.
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 the MBU 125 Under-Desk Mounting Kit (part #70-077-01). To mount the PS 124 under a desk or other furniture, follow these steps: 1. Attach the mounting brackets to the power supply with the provided machine screws (figure 10). 2. Hold the power supply with the attached brackets against the underside of the furniture.
PS 124, cont’d Above-projector mounting PMK 350 The PMK 350, (part #70-563-03), is an above-projector mounting kit that attaches to a 1" to 2" diameter projector mounting pole (figure 11). It can hold multiple devices in a variety of sizes. N These instructions are for the PMK 350. If another above‑projector mounting is used, follow the installation instructions for that kit.
5. Assemble the U-bolt and the following parts in order: a. Pass the legs of the U-bolt through the slotted holes on the mount plate flange. b. Place the legs around the ceiling pole. c. Pass the legs through the holes in the contoured base. N The pole fits snugly into the depression in the center of the contoured base. d. Pass the legs through the holes in the L-shaped bracket. N The bracket slots can accommodate 1.0" to 2.0" diameter poles. The supplied square U-bolt fits 1.5" to 2.
