The Sorensen DLM32-125E is a 4000W programmable DC power supply engineered for demanding laboratory and production test environments. This compact 2U chassis unit delivers 0–32V DC and 0–125A DC with exceptional output stability and low noise characteristics. It operates in both constant voltage (CV) and constant current (CC) modes, each indicated by dedicated status LEDs. The supply features adjustable overvoltage protection, overtemperature shutdown, and reverse polarity protection for safe, unattended operation.
