| Schaefer introduces 22KW power converters  Schaefer has introduced the C/B 6400 Series of 22,000 Watt, 8U high, 19" wide rack mount DC/DC and AC/DC converter modules. This compact and robust design provides a high density, space-saving solution for high power applications in industries such as railway controls and communications equipment, military applications, fuel cell applications, transportation, telecommunication systems, process control systems, and power stations. The C/B 6400 Series is available in 2 standard DC input voltage ranges of either 320-640VDC or 450-800VDC, as well as 3-Phase AC input voltages of either 3 x 400VAC or 3 x 480VAC.All modules in the C/B 6400 Series feature front to back cooling with a standard operating temperature of –20°C to +75°C, with an option for –40°C. All C6400 models have remote sensing up to 150V output. All Series' models have overvoltage protection, current limit protection on the output, and thermal shutdown with auto restart. Efficiencies run up to 95% These highly dense units are packaged in a 8U x 19" x 552mm rack module for space savings and incorporate terminal / bolt / bar connection points. Options available include decoupling diodes for parallel / redundant operation, 'ruggedization', inhibit, Power Fail / DC-OK alarms, system reset, active current sharing, and programming/monitoring. write your comments about the article :: © 2006 Construction News :: home page |
