The Sorensen DCS300-3.5E is a programmable DC power supply delivering 1050 W across a 0–300 VDC, 0–3.5 ADC output range. Built into a compact 43 mm high chassis, it combines high power density with automatic constant-voltage/constant-current crossover, making it suited for manufacturing test, burn-in, R&D, and process control environments. The supply maintains 0.1% line and load regulation, recovers from load transients within 500 μs, and includes adjustable over-voltage protection and remote sensing compensation.
