Description

The Bel VRPB-10Dxxx is part of the low cost non-isolated dc/dc power converter series. The modules use a SIP

package for ease of layout and space savings. The output is closely regulated and the efficiency is typically 93%

at full load. Typical features include Remote On/Off, under-voltage lockout, over-current protection and short

circuit protection.
