The Sorensen DHP25-265 is a 25 kW DC power supply designed for industrial test, burn-in, and laboratory environments requiring precise voltage and current control. Operating from 0–25 V and 0–265 A, it delivers stable, accurate power across constant voltage, constant current, and constant power modes. Output stability reaches ±0.05% of full scale after an 8-hour warm-up, with line and load regulation at 0.1% and ripple under 0.01% p-p. The unit supports three-phase input (Delta or Wye) and integrates analog, IEEE-488.2, and RS-232 control interfaces for seamless integration into automated test systems.
