The Sorensen DCS60-20E is a 1.2 kW programmable DC power supply engineered for laboratory, industrial, and ATE system integration applications. Built on high-frequency switching technology, this 1U rack-mount unit delivers 0–60 VDC at 0–20 A in a compact 19.0 in × 17.52 in footprint weighing 19 lbs. The supply operates in constant voltage and constant current modes with automatic crossover, maintaining line regulation of 0.1% or 0.05% of maximum output and load regulation of 0.1% or 0.02% across 0–100% load variation. Front-panel 10-turn potentiometers enable precise voltage and current adjustment with simultaneous digital display.
