BP03x7AH-05A
Description
The Bel S7AH-05A and V7AH-05A 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 0.9V to 5.0V. They are pack-
aged in a compact, overmolded package rated at 5A. 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 ranges (-40擄 to +85擄 C). The output is closely regulated and the
efficiency is typically 91.5% at full load. 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.
