Packing 7.8W/cu. in. of power into a 4U high, hot-pluggable package designed for critical fault-tolerant applications in telecom, network and other distributed power systems, MRF2800 Series of telecom rectifiers offers high reliability, an efficiency of 91%, and series output diode and active input PFC to minimize harmonic distortion. Each fan-cooled unit delivers up to 2800W of output power and can include a comprehensive alarm signals package with front-panel LED meters. A thermal management system adjusts the fan speed to suit the load and ambient temperature. A single unit is capable of providing either 50A at 48/54V or 100A at 24/27V.
