Description

The Bel xRAH-03L2A0 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 an output voltage range from 0.9 Vdc to 5 Vdc. It is

packaged in a compact, overmolded package rated at 3 A (0.9 Vdc-3.3 Vdc) and 2 A (5 Vdc). 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 91% at full load. Typical features include remote

on/off, over current protection and short circuit protection.
