The Sorensen SG Series of programmable high-power dc power supplies offer four new output voltage offerings of 10, 15, 20, and 30 Vdc. These units have output power specifications ranging from 4 to 15 kW. The 20-Vdc model supplies up to 750 A in a standard 3U package, while the 10-Vdc 12-kW unit can deliver up to 1,200 A in a 3U form factor.
The dc power supplies feature voltage and current slew rates, and up and down programming. They have power factor correction with three-phase 208-, 400-, and 440/480-Vac input with the standard unit supporting both 50/60-Hz and 400-Hz ac-input frequency. All of the models in the SG Series are available with either Sorensen General-purpose Intelligent (SGI) control or Sorensen General-purpose Analog (SGA) control. SGI controls enable sequencing, constant power mode, and save/recall of common setups. Units with SGA control have simple front panel analog controls or remote analog control and features 10-turn potentiometers for setting voltage and current, as well as front-panel OVP preview/adjustment and reset.
