Description
The Bel xRAH-03L1A0 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 3.3 Vdc. It is
packaged in a compact, overmolded package rated at 3 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 for 3.3 Vdc output is typically 88% at full load. Typical features include remote on/off, over current
protection and short circuit protection.
