The Sorensen DCR600-4.5B is a 2700 W high-power DC power supply engineered for demanding laboratory and industrial burn-in and test applications. This SCR-controlled unit delivers up to 600 Vdc at 4.5 A with exceptional voltage and current regulation, supporting both constant voltage and constant current operating modes. Remote voltage and current programming via 0-10 Vdc and 0-0.4 A inputs enable flexible system integration. Adjustable current limiting provides automatic overload and short-circuit protection with full recovery. Standard overvoltage protection is factory-installed and fully adjustable across all models.
