Description
The Bel SRAH-08B and VRAH-08B modules are a series of non-isolated, step down DC/DC power converters that operate
from a nominal 5V source. These converters are available in a range of output voltages from 0.9V to 3.3V. They are packaged
in a compact, overmolded package rated at 8A. 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, output voltage adjust and industrial temperature range (-40° to +85° C). The output is closely regulated and the
efficiency is typically 92% at full load. These products may be used almost anywhere low voltage silicon is employed and a 5V
source is available. Typical applications include file servers, routers, line cards and other computing and communications
equipment.
