The ultra-high efficient 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 3×200, 3×400 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%. 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.
