Sorensen DCR40-13B

The Sorensen DCR40-13B is a 500 W programmable DC power supply engineered for laboratory, industrial, and burn-in test environments. This unit delivers 0–40 V DC at 0–13 A with precise voltage and current regulation, automatic CV/CC mode crossover, and integrated overload protection. The SCR-controlled input regulator ensures stable output across line and load variations, supported by low-level remote sensing and adjustable current limiting for reliable operation under demanding conditions.
