Description

The Bel xRAH-07A1A0 modules are a series of non-isolated, step down dc/dc converters that operate from a

nominal 12 Vdc source. These converters are available in a range of output voltages from 0.9 Vdc to 3.3 Vdc. It is

packaged in a compact, overmolded package rated at 7 A. 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 is typically 88% for 3.3 Vdc output at full load. Typical features include remote on/off, input under

voltage lockout, over current protection and short circuit protection.
