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 6U design provides a solution for the most extreme environments in industries such as rail and transit for railway controls, communications equipment and beyond.
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 12 standard ranges encompassing 5VDC-400VDC.
The C3700 Series has comprehensive protection circuitry and efficiencies are up to 95 percent. 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.
