The Sorensen SRL40-12 is a 500 W DC power supply delivering 0–40 Vdc at 0–12 Adc for precision testing, bench diagnostics, and industrial applications. It combines constant voltage and constant current regulation with automatic crossover, remote programming via voltage or resistance input, and remote sensing for load-independent output control. Front-panel-adjustable over-voltage protection eliminates the need to interrupt AC power or disconnect the load during setup and monitoring.
