The Sorensen XTS15-4 is a 60 W programmable linear DC power supply for benchtop and system integration. It delivers 0–15 V and 0–4 A with line regulation of 0.02% (voltage) and 0.03% (current), making it suitable for electronics testing, circuit prototyping, and educational lab work. The unit operates in both constant voltage and constant current modes with automatic crossover, eliminating the need for manual switching during load transitions.
