Description
The Bel xRAH-10Jxx0 is part of the low cost non-isolated dc/dc power converter series. The modules use a SMD
or SIP package for ease of layout and space savings. The output is closely regulated and the efficiency of 1.5
Vdc output is typically 88% at full load. Typical features include remote on/off, input under voltage lockout, over
current protection and short circuit protection.
