Description

The Bel xRAH-01FXx0 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. The output is closely regulated and

the efficiency of 12 Vdc output module is typically 88% at full load. Typical features include burst mode

operation at light load and trim function (option).
