Schaefer, Inc. has introduced the C4700 series of 2,500W dc-dc converter, ac-dc power supply and battery charging products. The series is said to yield a highly efficient, space-saving solution for even the most extreme environments in industries such as railway controls and communications equipment (onboard and trackside), military applications, alternative energy applications, transportation, and process control systems.
The C4700 series features an extensive lineup of over 200 standard models, with requests for modifications also available. Nine standard dc input voltage options range from 10 - 800Vdc. Ac input models offer either 1-Phase or 3-Phase options as well as battery charging models. Single outputs are available in twelve standard ranges encompassing 4.5 - 400Vdc. All outputs are adjustable and fully regulated to 0.2% or better (load) and 0.1% (line).Dc-dc and ac-dc models have remote sense capability. The C4700 series has comprehensive protection circuitry and efficiencies are up to 95%. Operating temperature is -20 to +75°C, with -40 to +75°C as an option.
The units are packaged in a 6U x 19" x 306mm rack module, a wall mount module, or a newly introduced chassis mount configuration. Options include decoupling diodes for parallel/redundant operation, further mechanical ruggedization, inhibit, Power Fail/DC-OK alarms, system reset, and programming/monitoring functions.
