Schaefer, Inc.: 1250W converters and battery chargers

Schaefer, Inc. introduced the C3700 Series of 1250 Watt DC-DC and AC-DC converter modules and battery charger. Utilizing industrial grade components, the compact and robust 6U design works in extreme environments across industries such as rail and transit for railway controls, communications equipment, and beyond (onboard and wayside), as well as in military applications, alternative energy applications, and process control systems.

The C3700 Series delivers up to 1250W of power and offers nine standard DC input voltage ranges from 18VDC up to 640VDC. AC input options are single-phase 115VAC or 230VAC (with or without PFC) or three-phase inputs of 3x200, 3x400 and 3x480VAC. Single outputs are available in twelve standard ranges encompassing 5VDC-400VDC. 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% the company says. 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.
