Description
The Bel x7AH-08E1A0 modules are a series of non-isolated, step down DC/DC converters that operate from
4.5V to14V source. These converters are available in a range of output voltages from 0.8V to 5.5V. It is
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. The output is closely regulated and
the efficiency for 5V output is typically 93% at full load.
