Description
The Bel VRPC-10C series modules are non-isolated, DC/DC power converters that operate from a nominal 3.3V source. These converters are available in a range of output voltages from 1.5V to 2.5V. They are packaged in an industry standard single-in-line footprint with 10A maximum output. Standard features include remote on/off, over current and short circuit protection and output voltage adjust. Remote sense is an optional feature. These products may be used almost anywhere low voltage silicon is employed and a 3.3V source is available. Typical applications include file servers, routers, line cards and other computing and communications equipment.
