Description
The Bel xRAH-01H1A0 is part of the low cost non-isolated dc/dc converter series. The modules use a SMD or
vertical mount package for ease of layout and space savings. The output is widely trimmed from 1.2 V to 3.3 V.
Typical features include remote on/off, input under voltage lockout, over current protection and short circuit
protection.
