Many AV systems are likely to include a number of compact products, such as Extron MTP - Mini Twisted Pair Series, MediaLink, and IP Link products. Typically, they each operate using a 12VDC power supply. But with several of them in a rack, each individually powered, the availability of electrical receptacles becomes an immediate issue. A power strip can easily solve the problem, but then there's still the clutter of all the cables, adapters, and rack space necessary for these products.

This is where the new Extron PS 124 comes in. It's a versatile problem solver that addresses the question of how to effectively power a number of Extron products in a system. The PS 124 is a compact, rackmountable 12 Volt, 4 Amp power supply, and can provide the power necessary for several devices as a neat, compact solution.

Reduce Rack Clutter with a Single Power Supply

In a rack, a PS 124 replaces extraneous dangling wires and multiple power supplies by offering the capability to power several products at once. In doing so, the PS 124 also frees up valuable rack space that would or could have been occupied by an array of power supplies.

Eight 12VDC outputs are provided on captive screw connectors. Therefore, you can easily run DC wiring from any output of the PS 124 directly to each device. Using custom wiring lengths, you can achieve a clean, streamlined installation, and also remotely power any devices that a standard power supply otherwise would not reach. In addition to reducing rack clutter, an installation with the PS 124 reduces the number of possible points of failure and also simplifies troubleshooting.

Power Multiple Products Simultaneously

There's no limit on the current that can be drawn through each individual output, as long as the total for all sources powered through the PS 124 does not exceed 4.0 amps. Since many compact Extron products require less than 0.3 amps, the PS 124 will provide ample power for at least eight devices in a system. Should the PS 124 ever be overloaded, LED indicators on the front and rear panels, shown as green under normal operating conditions, will illuminate red.

An Ideal Choice for Pole-Mounted AV Systems

The PS 124 is also an ideal choice when integrating a small AV system installed near a ceiling-mounted projector, providing power to adjacent AV devices via very short, inconspicuous DC wiring runs. To further streamline the installation, the PS 124, in combination with the optional Flexible Conduit Adapter Kit, can be hard-wired into the electrical run above the ceiling, so that no electrical receptacle will be necessary. The use of this conduit adapter kit also makes the PS 124 plenum-rated, so that it too can be installed above the ceiling.

 

Need a Plenum-Rated Power Supply?

Extron's new PS 124 Flexible Conduit Adapter Kit - part # 70-228-02 - allows the PS 124 to be permanently installed in plenum environments. Plenum environments are typically associated with the area above a suspended ceiling but include any area utilized for air handling within a building or structure, including raised flooring. AC power is hardwired to the PS 124 with all wiring encased in flexible conduit. The PS 124, in conjunction with the Flexible Conduit Adapter Kit meets UL 2043 for smoke and heat release. Be sure to check local building codes to verify whether additional conformance requirements are necessary.

 

Centralized Power in a Compact Device

The PS 124 is an economical problem solver that serves as an ideal complement to AV systems with several compact devices. In addition to rack and above-the-projector equipment, the PS 124 can also power devices installed in a wall, such as a MediaLink Controller. This would easily address the challenge of powering in-wall products that require a 12 VDC power source.

In many cases, the PS 124 can serve as the centralized power source for a number of products located throughout a room. The diagram below illustrates such an example, with the PS 124, mounted within the plenum airspace with the optional conduit adapter kit, powering six products. Two of them – the MTP R 15HD A and MTP R AV RCA twisted pair receivers – are located just above the projector. In addition, an MTP T AV AAP and two MTP T 15HD A AAP twisted pair transmitters, along with an MLC 104 IP Plus MediaLink Controller are remotely situated at the wall. This scenario allows for a clean, totally discreet installation without the use of a single AC adapter or even an electrical receptacle.

Summary

The Extron PS 124 provides several benefits as a compact, centralized source of power in many AV systems:

• Replaces the need for multiple 12VDC power supplies to power devices, reducing rack clutter.
• Provides 4.0 amps total current output with no per-port current limitation.
• As a source of centralized power, the PS 124 reduces possible points of failure and simplifies troubleshooting.
• Compact housing for installation in a rack or above a projector.
• Using cut-to-length DC wiring, the PS 124 can power remotely located devices, such as in a wall.
• The optional Flexible Conduit Adapter Kit enables installation of the PS 124 within a plenum airspace, providing a fully discreet installation.
