Description
The Bel V7PC-10A series modules are non-isolated, step down DC/DC power converters that operate from a nominal 12V
source. These converters are available in a range of output voltages from 1.5V to 3.3V. They are packaged in an industry
standard single-in-line footprint and provide a maximum 10A output. Standard features include remote on/off, over current
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 12V source is available. Typical applications include file servers, routers, line cards
and other computing and communications equipment.
