Laboratory power supplies in linear technology with separate LCD digital displays for voltage and current. Ideal for laboratories, workshops, and production due to the high consistency of output parameters. Robust construction and easy operation. Permanently short-circuit proof with very good regulation behavior and low residual ripple. 10-turn spiral potentiometer for precise adjustment of output voltage. The devices can be operated as either constant voltage or constant current sources. The outputs of the dual power supplies can be connected in series or parallel. The devices are equipped with over-temperature protection and presetting of output data without load.
