The Sorensen SRL10 is a adjustable DC power supply engineered for electronic testing and development applications requiring stable, programmable outputs. It delivers constant voltage/constant current (CV/CC) operation with automatic crossover, transitioning between modes based on load conditions. The unit integrates a linear series pass design with preregulation, achieving low ripple and noise performance across its output range. Front-panel adjustable crowbar overvoltage protection activates in 10 µs without requiring power removal. Remote programming via resistance or voltage signals enables integration into automated test systems, while remote sensing capability ensures accurate regulation at the load.
