The Sorensen DHP120-16 is a single-output DC power supply delivering 120V at 16A for demanding test, research, and development applications. Operating in constant voltage, constant current, and constant power modes, this unit combines precise programmability with analog and digital control interfaces. The supply features 0.1% voltage regulation, 0.5% current regulation, and exceptional output stability of ±0.05% over 8-hour intervals. Second-generation control technology enables up to 9 auto-sequence steps with durations from 1 second to 99,999 seconds, making it suitable for complex test protocols and unattended operation.
