UL60950 Recognized (UL/cUL)
Description
The Bel xRAH-03F1A0 module is a non-isolated, step down dc/dc converter that operates from 3.0 Vdc to 5.5
Vdc source. This converter is 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 3 A. Optional lead forming provides a vertical mount product for minimal
footprint or a surface mount option for a very low profile. The efficiency of 3.3 Vdc module is typically 92% at 5
Vdc input and full load. Typical features include remote on/off, input under voltage lockout, over current
protection and short circuit protection.
