Power converters offer efficiency in extreme environments

Schaefer Inc., a manufacturer of power supplies, announces the C4500HV Series of high output voltage power converters. The new converters can accept high input voltages of up to 3,000 Vdc and are suitable 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 on the company’s C/B4500 Series, which offers an extensive lineup of more than 150 standard models. Standard dc input voltage options span a range from 10 to 800 Vdc, while ac input models offer either 1 or 3-Phase options as well as battery charging models. Single output voltages encompass a range from 9 to 400 Vdc, all of which are adjustable and fully regulated to 0.2% or better (load) and 0.1% (line).

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