900-, 960-W supplies are priced economically

Five switch mode dc power supplies — models 1900, 1901, and 1902, and models 1693 and 1694, — are all under-$600 models whose features suit them for R&D, production, service, and education. The 960-W 1900, 1901, and 1902 models offer constant current mode auxiliary output, rotary encoder knobs for precise level setting, and user-defined presets for quick recall of common test parameters. They also have remote sensing to compensate for voltage drops due to load lead resistances.

The lightweight, compact 900-W 1693 and 1694 models provide voltage output from 1 to 15 V at 60 A and 1 to 30 V at 30 A, respectively, remote sensing terminals, and an auxiliary output. All models have an analog remote control terminal for external adjustment of output voltage or current and three-digit LED displays for both voltage and current. The instruments also have over-temperature and over-voltage protection, and current foldback circuitry to prevent overloading. (1693 or 1694, $479; 1900, 1901, or 1902, $599 — available now.)
