The Sorensen DHP250-120M2M51 is a 30 kW programmable DC power supply designed for laboratory, industrial automation, and automated test equipment environments. It delivers 0–250V DC at 0–120A with excellent voltage and current regulation, low ripple and noise, and integrated protection mechanisms. The unit operates from 480V AC 3-phase 50A input and features modular rackmount construction with dual operational modes (CV/CC), up to 9 auto-sequence steps with individually programmable durations up to 99,999 seconds, and digital displays for real-time monitoring of power, voltage, current, and thermal parameters. Optional interfaces include IEEE-488.2, RS-232, and isolated analog programming for seamless integration into automated test systems.
