Description
The Bel S7AH-02A and V7AH-02A 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 packaged in a
compact, overmolded package rated at 2A. 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° to +85° C). The output is closely regulated and the efficiency is
typically 89% 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.
