The Sorensen XTD15-4 is a single-output programmable DC power supply engineered for benchtop and automated test environments demanding stable, precision power delivery. Operating at 0–15 VDC and 0–4 A, the unit delivers 60 W with excellent line and load regulation, output noise below 4 mV RMS, and automatic crossover between constant voltage and constant current modes. Programming accuracy reaches ± (10 mV + 0.1% of set voltage) for voltage and ± (110 mA + 0.1% of set current) for current. The compact quarter-rack form factor accommodates dense system integration while remote sense terminals enable load voltage compensation across extended leads.
