DC-DC Converters – Performance That Scales With You

DC DC converters have been a cornerstone of Relec Electronics’ portfolio since our inception in 1978. Our extensive expertise and diverse range of products, spanning from 1W up to 6kW, enable us to deliver unparalleled technical support, saving you valuable time, effort, and cost.

Our comprehensive DC DC converter offering covers power ranges from 1W to 6000W, input voltages from 3Vdc to 400Vdc, and output voltages starting from as low as 0.8Vdc. Our extensive selection includes regulated and unregulated converters, isolated and non-isolated configurations, and both buck converter and boost converter solutions. We also supply BUS voltage converters designed specifically for industry-standard requirements.

For optimal thermal management, we provide DC-DC converters that are conduction cooled and convection cooled. Our range includes industry-standard brick formats, as well as DC conversion modules with fixed input and wide input ranges (2:1 and 4:1), ensuring we meet your precise requirements.

Should our standard range not fully align with your specifications, our dedicated engineering team is available to discuss DC-DC conversion customised designs tailored specifically to your application.

With over 40 years of close collaboration with leading manufacturers, Relec Electronics stands ready to guide and support you throughout every stage of your design process. We also carry comprehensive stock of standard DC DC converter modules for prompt delivery, ensuring your project stays on schedule.
