Description
The Bel VRPB-06F33H modules are a series of non-isolated high density open frame dc/dc converters that can
deliver up to 6 A of output current with full load efficiency of 94% at 3.3 Vdc output. Their open-frame
construction and small footprint enable designers to develop cost and space-efficient solutions. Standard features
include remote On/Off, power good output signal, over current protection and short circuit protection.
