BW2901
The BW2901 family provides compact single-phase AC-DC conversion for airborne, naval and mobile defense electronics. Available configurations convert 115 VAC into regulated 24 or 28 VDC output, with power ratings from 300 to 600 W for communications, control, sensing and mission-computing loads.
Active current sharing allows compatible units to be paralleled for as much as 2.4 kW. The design includes input-to-output isolation, short-circuit protection and a 2 ms hold-up time, and is intended for applicable requirements of MIL-STD-704, MIL-STD-810, MIL-STD-461 and relevant naval power and environmental standards.
