Description
The Bel xRAH-01Hxx0 series are part of the low cost non-isolated dc/dc converter series. These modules use a
SMD or vertical mount package for ease of layout and space savings. The output is closely regulated and the
efficiency of 5 Vdc output is typically 90% at full load. Typical features include remote on/off, input under voltage
lockout, over current protection and short circuit protection.
