Description
The Bel SRAH-07C and VRAH-07C modules are a series of non-isolated, step down DC/DC power converters that operate
from a nominal 3.3V source. These converters are available in a range of output voltages from 0.9V to 2.5V. They are pack-
aged in a compact, overmolded package rated at 7A. Optional lead forming provides a vertical mount product for minimal
footprint or a surface mount option for a very low profile. Standard features include remote on/off, over current and short circuit
protection, and output voltage adjust. 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.
