Description
The Bel V7PB-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 1.0V to 5.0V. They are packaged in an industry
standard single-in-line footprint and provide a maximum 10A output. Standard features include remote on/off, remote sense,
over current and short cicuit protection, overtemperature shutdown and output voltage adjust. Remote on/off logic 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.
