Converter and battery charger series for extreme conditions
Schaefer's C3700 Series is a converter and battery charger for extreme conditions and delivers up to 1250 W of power and offers nine standard dc input voltage ranges from 18 V dc up to 640 V dc.
Schaefer's C3700 Series is a converter and battery charger designed for extreme environments in industries such as rail and transit for railway controls, communications equipment, and beyond (onboard and wayside), military applications, transportation, alternative energy applications, and process control systems. The C3700 Series delivers up to 1250 W of power and offers nine standard DC input voltage ranges from 18 V dc up to 640 V dc. The ac input options are single-phase 115 V ac or 230 V ac (with or without PFC) or three-phase inputs of 3x200, 3x400, and 3x480 V ac. All outputs are adjustable and regulated to 0.2% (load) and 0.1% (line). The C3700 Series has protection circuity and efficiencies are up to 95%. Features include natural convection cooling and a standard operating temperature range of -20 to 75 C. The dc-dc and ac-dc models have remote sense capability. Options include decoupling diodes for parallel/ redundant operations, further mechanical ruggedization, inhibit, power fail, dc-OK alarms, system rest, and programming and monitoring functions.
