Description
The Bel xRAH-12Fxx0 series are part of the low cost non-isolated dc/dc converter series. These converters are
available in a range of output voltages from 1.0 Vdc to 3.3 Vdc. It is packaged in a compact, overmolded
package rated at 12 A. The output is closely regulated and the efficiency of 3.3 Vdc output module is typically
93% at full load. Typical features include remote on/off, input under voltage lockout, over current protection and
short circuit protection.
