Description
The Bel xRPF-20A1A0 is a new high density open frame non-isolated converter series for space sensitive
applications. Each model has a wide input range (10.2 Vdc - 13.8 Vdc) and offers a wide range of output voltage
(0.9 Vdc - 5.0 Vdc) with a 20 A load. An external resistor adjusts the output voltage from its pre-set value of 0.9
Vdc to any value up to the 5.0 Vdc maximum. Typical efficiency is 92% at Vo=5 Vdc, Vin=12 Vdc at full load.
Typical features include remote on/off, under-voltage lockout, over-current protection and short circuit protection.
