The Sorensen DCR110-45T is a programmable DC power supply rated for 5 kW maximum output, delivering 0–110 VDC at 0–45 ADC. Built for industrial, laboratory, and demanding test environments, it offers precise voltage and current regulation with 0.1% line and load combined regulation in constant voltage mode, and 0.1% regulation in constant current mode. The unit features 40 ms transient response to ±1% band for 50–100% load steps and supports both 0–10 V and 0–10 kΩ resistive programming. Three-phase AC input accepts 208 Vac, 380 Vac, 400 Vac, 405 Vac, 440 Vac, or 480 Vac at ±10% tolerance, with 60 Hz standard and 50 Hz available. Forced-air cooled in a Case Size II enclosure weighing 53 lbs, the supply operates from 0 to +70°C ambient and includes overvoltage protection, phase loss shutdown, and thermal shutdown. Remote sense capability and full remote control enable flexible integration. Units support direct parallel connection without limits and series operation to 200 VDC maximum. Standard digital metering and EMI-protected AC line input round out the specification.
