Laboratory power supplies in linear technology feature separate LCD digital displays for voltage and current. They are ideal for laboratories, workshops, and production due to their high constancy of output parameters. With a robust construction and simple operation, these devices are continuously short-circuit proof and offer very good control behavior, as well as low residual ripple. A 10-turn spiral potentiometer allows for precise adjustment of the output voltage. The devices can operate as either constant voltage or constant current sources. The outputs of the dual voltage sources can be connected in series or in parallel. Additionally, the devices are equipped with overtemperature protection and presetting of the output data without load.
