Description

The Bel X7AH-12F1A0 is part of the low cost non-isolated dc to dc converter series. This converter is available

in a range of output voltages from 0.9V to 3.3V. It is packaged in a compact, overmolded package rated at 12A.

The output is closely regulated and the efficiency of 3.3V output module is typically 93% at full load. Typical

features include remote on/off, input under voltage lockout, over current protection and short circuit protection.
