Built for Demanding Applications

Relec Electronics offers a comprehensive range of chassis mount AC-DC power supplies, with output power ratings up to 24kW. Our portfolio includes industry-standard formats such as 3″ x 2″, 4″ x 2″, and 5″ x 3″, many of which are optimised to fit compact enclosures, including 1U-high “pizza box” designs.

Our chassis-mounted solutions feature advanced thermal management, and our engineers can advise on optimal airflow and cooling requirements. Many models support operation down to -40°C, and our medical-grade options are fully EN60601-compliant. For transportation and military use, we offer Euro cassette products that are convection-cooled and highly resistant to vibration—with optional chassis mounting kits available.

We also provide configurable chassis mount power supplies, allowing engineers to create multi-output solutions within a single enclosure. These power supplies offer 1 to 12 outputs, from 200W to 24kW, and are available for industrial, medical (EN60601), and military applications. Thanks to stocked chassis and modules, we can often ship configured units next day.

Open Frame AC-DC Power Supplies

In addition to enclosed units, we supply a wide range of open frame AC-DC power supplies up to 1000W. These come in 2″ x 4″ and 5″ x 3″ footprints, as well as larger U-channel and PCB mount formats. Like our enclosed range, they feature robust thermal design and benefit from our in-house technical support.

If our standard range doesn’t quite meet your needs, we offer full custom and variant services through our trusted manufacturing partners.

With over 40 years’ experience in the automotive, industrial, and defence sectors, Relec is trusted for reliability, service, and support. Our dedicated engineers and in-stock inventory mean we’re ready to help—from first contact through to delivery.
