Description
The Bel SRAH-03A and VRAH-03A modules are a series of 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 5.0V. They are pack-
aged in a compact, overmolded package rated at 3A. 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
12V source is available. Typical applications include file servers, routers, line cards and other computing and communications
equipment.
