Power converter accepts high input voltage range

The C4500HV Series can accept high input voltages of up to 3000 Vdc.

Ashland, Mass., January 11, 2010—Schaefer Inc., a manufacturer of power supplies, announces the C4500HV Series of high output voltage power converters. The C4500HV Series can accept high input voltages of up to 3000 Vdc. The converter provides high output voltages and is very useful for applications that require reliable power for remote locations.

The Series’ robust design, using industrial grade components, yields a highly efficient, space-saving 6U solution for even the most extreme environments.

The C4500HV Series is based upon Schaefer’s C/B4500 Series, which offers an extensive lineup of over 150 standard models. Standard DC input voltage options span a range from 10 Vdc to 800 Vdc. AC input models offer either 1- or 3-phase options as well as battery charging models. Single output voltages encompass a range from 9 Vdc to 400 Vdc, all of which are adjustable and fully regulated to 0.2 percent or better (load) and 0.1 percent (line).

Remote sense capability and comprehensive protection circuitry is inherent in the design, with efficiencies up to 90 percent. Operating temperature is -20 to +75 degrees C, with -40 to +75 degrees C as an option. Additional options include parallel/redundant operation, further mechanical ruggedization, inhibit, Power-OK/DC-OK alarms, and system reset.
