1,250-W converters handle extreme environments

Oct. 3, 2015

Hopkinton, MA. Schaefer Inc. has introduced the C3700 Series 1250-W DC/DC and AC/DC converter modules and battery chargers. Utilizing industrial-grade components, the compact and robust 6U design provides an efficient, space-saving solution for extreme environments in industries such as railway controls, communications equipment, military applications, transportation, alternative energy, and process control.

The C3700 Series delivers up to 1250-W of power and offers nine standard DC input voltage ranges from 18 VDC up to 640 VDC. AC input options are single-phase 115 VAC or 230 VAC (with or without PFC) or three-phase inputs of 3×200, 3×400, and 3×480 VAC. Single outputs are available in twelve standard ranges encompassing 5 VDC to 400 VDC. All outputs are adjustable and fully regulated to 0.2% or better (load) and 0.1% (line).

The C3700 Series has comprehensive protection circuitry and efficiencies are up to 95%. Featuring natural convection cooling and a standard operating temperature range of -20°C to +75°C (derate 2.5%/°C from +55°C), with an option for -40°C to +75°C. DC/DC and AC/DC models have remote-sense capability. Options include decoupling diodes for parallel/redundant operation, further mechanical ruggedization, inhibit, Power Fail/DC-OK alarms, system reset, and programming/monitoring functions.
