The Sorensen DLM80-50E is a programmable DC power supply engineered for precision benchtop and system-level test applications requiring stable, regulated output across demanding operational windows. This unit delivers 0–80 VDC at 0–50 ADC, yielding 4 kW total power in a space-efficient 2U (3.5-inch) rackmount chassis with no top or bottom clearance requirements.
