Schaefer Announces New Water Cooled 8000W Power Converter
Schaefer, Inc. introduced the CW5300 series of water cooled, 8000W dc-dc and ac-dc converter modules. The series’ compact, yet robust, design is said to yield high power density, and to offer 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 200, 3 x 400, 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 -20 to +75°C, with -40 to +75°C as an option.
The units are packaged in a space saving 5U x 19" x 600mm 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.
