LOW-COST D-C POWER SUPPLIES Standard output voltages from 3 to 1000 VDC at 30% intervals... Maximum powers of 50,100,200,400,750*, 1500% 3000** watts These new Sorensen MD supplies form one of the most comprehensive and economical power supply series on the market. M o r e than 1 3 0 catalog models to choose from, providing 20 output voltages in the range from 3 to 1000 vdc, inclusive. Sorensen engineers welcome the opportunity to develop non-catalog models for unusual requirements. Simple, rugged design features magnetic voltage regulator to obtain ± 1 % regulation against input line variations plus low-impedance silicon rectifier for good load regulation. (Typical regulation from 5 0 % load to full load is 2 % to 1 0 % , depending on load current rating. Additional data can be supplied upon request.) Ripple: 1 % rms max. (Some units can be supplied with 0 . 5 % max. ripple.) Dependable, tubeless construction. All parts are conservatively rated for continuous duty. Units will withstand output short circuits without damage to components. 19-inch rack-panel mounting for all units simplifies application in lab or custombuilt equipment. Rugged MD series supplies are just one example of the outstanding power-supply modelé offered by Sorensen. Sorensen controlled power equipment, with the widest line, enables you to make the wisest selection. Included are: regulated d-c supplies, regulated a-c supplies, variable frequency power sources (frequency changers; for example, 60 to 400 cps), high voltage supplies (to 600 kv, ac or dc), and miniature converters and inverters. Available in an extremely wide variety of input-output combinations. Write for complete specs. Sorensen & Company, Richards Ave., South Norwalk, Conn.
