July 14, 2002 by Jeff Shepard

Schaefer Inc. (Ashland, MA) introduced its new SLPS Series of 20kW, 8U high, 19in, rack-compatible, ac/dc converters. Typical applications include battery charging as well as battery, fuel cell and solar power simulation.

The SLPS Series is available with 480V, three-phase input and output ranges from 0V to 600V and 0A to 350A with a single-unit output power of 20kW. Up to six units may be configured in parallel for a total output of 120kW. All outputs are adjustable and fully regulated to 0.2 percent or better (load) and 0.1 percent (line).

All units in the SLPS Series have remote sensing, over-voltage protection and current-limit protection on the output. Zero switching allows for efficiency as high as 93 percent, depending on input and output configurations.
