Extron Power Supplies - Designed and Engineered for Efficiency and Reliability

While most manufacturers purchase off-the-shelf switch mode power supplies that can be subject to variations in quality and reliability, we now design and manufacture our own, ensuring Extron quality throughout the product. In 2004, we brought in power system engineering expertise to address various power supply issues and began to design the best power supplies for ourselves. As a result, we now control the entire design and engineering process for all Extron power supplies, concentrating on ways to avoid reduced lifespan and overheating issues that all AV system manufacturers face.

PS Series Desktop Power Supplies

The energy-efficient Extron PS Series of Desktop Power Supplies consume just 0.3 watts or less in idle when no load is present on the output. In comparison, a typical desktop power supply may draw 2 watts of input power in idle. In order to keep operational costs minimized, every Extron PS Series Desktop Power Supply has an efficiency rating of over 80%.

Select PS Series power supplies qualify for Extron’s Trade-up Program that enables resellers to trade in 15 new, unused Extron 12 volt, 0.5, 1, and 1.5 amp power supplies for a new Extron PS 124 Multiple Output 12 Volt DC Power Supply. To learn more about this opportunity, please visit the Power Supply Trade-up Program page.

Internal Power Supplies

Extron also designs and engineers internal power supplies for our products. Conventional internal power supplies are at best 70% efficient, meaning that 30% or more of the input power is wasted as heat. Our larger internal power supplies achieve an even greater efficiency rating of up to 90%. This significant reduction in waste heat generation adds to the power supply’s lifespan.

Power supply failures in mission critical products can cause significant disruption to signal distribution and facility operations. Extron internal switch mode power supplies, like our desktop power supplies, enable reliable and efficient operation of the Extron products they power. These power supplies consume less energy and generate less waste heat than conventional power supplies. The result is a reduction in operational costs due to power consumption for the AV System and the HVAC costs required to keep the AV System environment within the required temperature range.

Demonstrated MTBF - Mean Time Between Failures

To ensure our power supplies meet Extron standards of performance and quality, we placed a sample quantity into a heat chamber to simulate an accelerated operational life span. This produced a demonstrated MTBF – Mean Time Between Failures – rather than a calculated MTBF that is based on the stated specifications of the individual components. The Extron PS Series power supplies have a demonstrated MTBF of up to 850,000 hours. See table below for MTBF by model. By comparison, our original power supplies had an MTBF of 30,000 hours. We know of no other company that has gone to such lengths to guarantee power supply reliability. PS Series power supplies are available in the most popular voltages used by Extron products: 12 VDC.

Accelerated Operational Life Testing

Our power supplies operated under load in this heat chamber at an ambient temperature of 85° C. Under these conditions, each hour was the equivalence of 64 hours to the power supplies being tested. Testing began in April 2008 and ended on May 28, 2010. After initial testing of the PS Series was complete, the PS 1205 C, PS 1215 C, PS 1220, and PS 1230 power supplies achieved an 850,000‑hour calculated MTBF. The PS 1242 has a calculated MTBF of 280,00 hours.

ZipClip Mounting System

With the included ZipClip^® mounting system, the desktop power supplies can be quickly and securely mounted to rack rails, tables, and lecterns. The unique enclosure design allows direct mounting to projector poles, table legs, and other oddly shaped structures.

One-Eighth Rack Width Versions

The compact one-eighth rack-width PS 1205, PS 1220, and PS 1215 models include an attached 3‑foot DC cord. The DC cord on each model is terminated with a captive screw connector.

One-Quarter Rack Width Version

The one-quarter rack width by 1U high PS 1242 power supply has three 2‑pole captive screw ports and offers a total of 4.2 amps across all outputs with no per-port current limitations. It features one detached 6‑foot DC cable with pre-sliced ends, three orange 2‑pole, 3.5 mm captive screw connectors, and a DC plug for convenient DC output creation.
