High Power DC-DC Converters

Rugged, Reliable Power Modules from 50~600 W

Featuring an ultra wide input, Bel Power Solutions, CUI brand High Power DC-DC Converter family is available in models ranging from 50~600 W. The converters are housed in industry standard pcb mount packaging or chassis mount packaging with an integrated heat sink for improved thermal performance. Most models have been designed with a 4:1 input voltage range to address applications where the source voltage can fluctuate greatly, including the unstable source voltages typical in battery-fed systems. With additional features that include high efficiency, tight regulations, remote sense, and remote on/off control, these converters are ideal for use in a range of industrial, security and communications applications.
