The Series' robust design, using industrial grade components, yields a highly efficient, space-saving solution for even the most extreme environments in industries such as railway controls and communications equipment, military applications, alternative energy applications, transportation, and process control systems.

The C4700 Series includes an extensive lineup of over 200 standard models, with requests for modifications also welcomed. Nine standard DC input voltage options span a range from 10 to 800VDC. AC input models offer either 1-Phase or 3-Phase options as well as battery charging models. Single outputs are available in twelve standard ranges encompassing 4.5VDC to 400VDC. All outputs are adjustable and fully regulated to 0.2 percent or better (load) and 0.1 percent (line).

DC/DC and AC/DC models have remote sense capability. The units have comprehensive protection circuitry and efficiencies are reportedly up to 95 percent. Operating temperature range is -20 to +75°C, with -40 to +75°C as an option.

The units are packaged in a space-saving 6U x 19-in. x 306mm rack module, a wall mount module, or a newly introduced chassis mount configuration.
