February 13, 2008 - Ashland, MA - Schaefer, Inc. introduces the CW5300 Series of water cooled, 8000 Watt DC/DC and AC/DC converter modules. The Series’ compact, yet robust, design yields an extremely high power density, offering a space-saving solution for even the most extreme environments in industries such as railway controls/communications equipment (onboard and trackside), military, alternative energy, transportation, and process control systems.
The CW5300 Series is available in 5 standard DC input voltage ranges from 80-800VDC, as well as 3-phase AC input voltages including 3 x 200VAC, 3 x 400VAC, and 3 x 480VAC. Single outputs are available in 9 standard ranges spanning 14-400VDC. All outputs are adjustable and fully regulated to 0.2% or better (load) and 0.1% (line).
All modules in the CW5500 Series have remote sensing (up to 150VDC output), overvoltage protection, and current limit protection. Efficiencies are up to 95%. Operating temperature is -20C to +75C, with -40C to +75C as an option.
The units are packaged in a space saving 5U x 19” x 600mm (HxWxD) rack module and incorporate terminal / bolt / bar connection points. Available options include decoupling diodes for parallel / redundant operation, “ruggedization,” inhibit, Power Fail / DC-OK alarms, system reset, active current sharing, and programming.
Mechanical and electrical modifications to standard modules are readily available upon request. In addition, Schaefer can design and manufacture fully custom solutions.
