Schaefer Introduces 3 & 5U Plug-in DC-DC & AC-DC Converters

Schaefer, Inc. has introduced the C5100 series of 5000W, 3 and 5U plug-in dc-dc and ac-dc converter modules. The C5100 series is available in 3 standard dc input voltage ranges from: 320-800Vdc, as well as 3 ac input voltages of 3 x 400Vac (320-460) and 3 x 480Vac (400-530). Single outputs are available in 6 standard ranges from 23-200Vdc. All outputs are adjustable and fully regulated to 0.2% or better (load) and 0.1% (line).

All modules in the C5100 series have remote sensing (up to 150V output), overvoltage protection, and current limit protection on the output. Efficiencies are up to 95%. Operating temperatures available include -20 to +75°C and also -40 to +75°C.

The units are packaged in a 3U x 40TE x 538 mm rack module for space savings and incorporate CombiTec I/O connectors. They can be rotated for 5U mounting. Available options include decoupling diodes for parallel/redundant operation, "ruggedization", inhibit, Power Fail / DC-OK alarms, system reset, active current sharing, and programming.

Applications include railway controls and communications equipment (onboard and trackside), military applications, transportation, telecommunication systems, process control systems, and power stations.
