Switching Power Supplies

The REL185 Series of ac/dc switching power supplies meet the performance and 1-U footprint needs of medical, communications, instrumentation, and industrial-control applications.

The supply accepts 85 to 264-Vac input and provides 185 W of output power with single, dual, triple, and quad output versions. The low-profile (4.2 X 7.0 X 1.5-in.) unit is available in open frame or with an optional chassis and cover that fit into 1-U applications. The units meet harmonic current standard EN61000-3-2 and EN60950 ITE and EN60601-1-2 medical standards. Features include EN55011/22 Class-B emissions compliance, remote sensing, overvoltage protection, and a power-fail signal.
