Powerful and compact switching power supply for laboratory applications. The voltage and current settings are continuously adjustable via digital rotary knobs with coarse and fine adjustments, allowing for quick and precise value settings. The values are displayed on a clear screen. The current limit for constant current operation can be preset without a short-circuit bridge. The output voltage can be accessed from the front via 4 mm safety sockets up to 5 A and from the rear high-current output up to the maximum current. The power supply is remotely controllable. The output voltage and output current can be adjusted via an external voltage (0 - 5 V/DC) or an external potentiometer (5 kOhm). The DC output can be switched on and off via a relay contact. Three freely programmable memory slots can be assigned different fixed voltages and current limits. The selector switch is located at the back. The device is overload and short-circuit proof and includes a safety temperature shutdown.
