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

advantage of a variety of mounting options (see (see page3).

FCC Class B Notice

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part15 of the

FCC rules. These limits provide reasonable protection against harmful interference in a residential installation. This equipment

generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may

cause harmful interference to radio communications. There is no guarantee that interference will not occur. If this equipment

does cause interference to radio or television reception, which can be determined by turning the equipment off and on, you are

encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

In order to maintain compliance with FCC regulations, shielded cables must be used with this equipment. Operation with non‑

approved equipment or unshielded cables is likely to result in interference to radio and TV reception. The user is cautioned that

changes and modications made to the equipment without the approval of the manufacturer could void the user’s authority to

operate this equipment.

NOTE: This unit was tested with shielded I/O cables on the peripheral devices. Shielded cables must be used to ensure

compliance with FCC emissions limits.

For information on safety guidelines, regulatory compliances, EMI/EMF compatibility, accessibility, and related topics, see the

Extron Safety and Regulatory Compliance Guide on the Extron website.

ATTENTION:

• Continued operation in an overload condition may cause premature power supply failure.

• Un fonctionnement ininterrompu en situation de surcharge peut entraîner la défaillance prématurée de la source

d’alimentation.

NOTE: To identify the shorted output, unplug the outputs one at a time until the Overload LED lights off.

Input Power

Apply power to the PS 125 using the

supplied IEC power cord.

ATTENTION:

• For permanently connected equipment, there must be a readily accessible disconnect device incorporated in the

building installation wiring.

• Pour les équipements branchés en permanence, un dispositif d’isolement rapidement accessible doit être intégré à

l’installation électrique du bâtiment.

• The circuit breaker used for this connection should be rated 20 amps maximum.

• Le disjoncteur utilisé pour cette connexion doit avoir une tension nominale de 20 A max.

Output Power — Wiring the DC Output Connectors

The PS 125 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.

ATTENTION:

• 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 wiring.

• Pour vérifier la polarité avant la connexion, brancher l’alimentation hors charge et mesurer sa sortie avec un voltmètre.

Couper l’alimentation avant de faire l’installation électrique.

• Ensure that you observe correct wire polarity. The two power cord wires must be kept separate while the power supply

is plugged in.

• Assurez‑vous de respecter la polarité correcte du câble. Les deux cordons d’alimentation doivent être maintenus à

l’écart tant que la source d’alimentation est branchée.

To connect products to the outputs of the PS 125:

1. Cut the DC output cord to the length required.

2. Strip the jacket of the conductor wire (see figure 3 on the right).

ATTENTION:

• The length of the exposed wires in the stripping process is . The ideal length critical

is 3/16 inches (5 mm). Any longer and the exposed wires may touch, causing a short

circuit. Any shorter and the wires can be easily pulled out even if tightly fastened by the

captive screws.

• La longueur des câbles exposés est lorsque l’on entreprend de les primordiale

dénuder. La longueur idéale est de 5mm (3/16inches). S’ils sont trop longs, les câbles

exposés pourraient se toucher et provoquer un court‑circuit. S’ils sont trop courts, ils

peuvent être tirés facilement, même s’ils sont correctement serrés par les borniers à vis.

• Do not tin the stripped power supply leads before installing the captive screw

connector. Tinned wires are not as secure in the captive screw terminals and could pull

out.

• Les câbles étamés ne sont pas aussi bien fixés dans les borniers à vis et pourraient

s’arracher. Ne pas étamer le câble d’alimentation dénudé avant d’avoir installé le

bornier à vis.

3. Slide the leads into the supplied 2‑pole captive screw plug and secure them using an Extron Tweeker or small screwdriver.

4. Use the supplied tie wrap to strap the power cord to the extended tail of the connector.

Mounting the PS 125

There are several optional accessories for mounting the PS 125 (see the mounting options at www.extron.com).

UL Rack Mounting Guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the installation of the PS 125 into a rack.

• Elevated operating ambient temperature — If installed in a closed or multi‑unit rack assembly, the operating ambient

temperature of the rack environment may be greater than room ambient. Therefore, consider installing the equipment in an

environment compatible with the maximum ambient temperature specied by Extron (Tma = +32 to +122 °F [0 to +50 °C]).

• Reduced air flow — Installation of the equipment in a rack should be such that the amount of air ow required for safe

operation of the equipment is not compromised.

• Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved

due to uneven mechanical loading.

• Circuit overloading — Consideration should be given to the connection of the equipment to the supply circuit and the

effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of

equipment nameplate ratings should be used when addressing this concern.

• Reliable earthing (grounding) — Reliable earthing of rack‑mounted equipment should be maintained. Particular attention

should be given to supply connections other than direct connections to the branch circuit (such as the use of power strips).
