The Sorensen DHP80-62-M2-M9D is a programmable DC power supply delivering 5 kW across 0–80 V and 0–62 A. Built for research, development, and industrial test environments, it combines precise voltage and current control with three operational modes: constant voltage, constant current, and constant power with automatic crossover. The M2 input option specifies 432–528 VAC, 47–63 Hz, 3-phase, 3-wire plus ground configuration (Delta or Wye compatible). The M9D option adds IEEE-488.2 digital interface capability for remote automation and control.
