Description
The Bel xRAH-06Exx0 is part of the low cost non-isolated dc/dc converter series. The modules use a surface
mount package or vertical package for ease of layout and space savings, with a low profile of only 7.82 mm. The
output is closely regulated and the efficiency of 3.3 Vdc output module is typically 91% at full load. Typical
features include Remote On/Off, under-voltage lockout, over-current protection and short circuit protection.
