The power supply has connection sockets for 4mm safety plugs on the front and massive screw terminals on the back with the possibility of inserting 4mm banana plugs, from which the maximum current can be drawn.

A switch can be used to switch between a fixed voltage of 13.8V and an adjustable voltage range of 9-15V. This offers a wide range of possible uses.

The adjustable interference suppression filter can filter out the frequently occurring interference from switching power supplies in sensitive devices.

Both the output voltage and the output current are shown on the digital display.

A temperature-controlled fan is used for cooling.

The power supply unit has output terminals up to max. 3A on the front, as well as a connection socket for a cigarette lighter plug up to max. 10A load. The maximum current of 30A can be drawn from the massive screw terminals on the back with the possibility of inserting 4mm banana plugs. A switch can be used to switch between a fixed voltage of 13.8V and an adjustable voltage range of 9-15V. This offers a wide range of possible uses. The adjustable interference suppression filter can filter out the frequently occurring interference from switching power supplies in sensitive devices. Both the output voltage and the output current are shown on the illuminated digital display. The cooling takes place via cooling fins as well as a built-in fan that can be switched on if required.

This controllable DC power supply unit is ideal for use in laboratories, workshops, car racing tracks or modelling. It is a precisely adjustable power supply in a solid sheet steel housing. The output voltage can be continuously regulated from 0-30 V. The current limit value (current intensity) can be set continuously from 0-20 A, whereby the voltage is reduced when it is reached.

The device is stabilized and short-circuit-proof by limiting the output current.

The heat is dissipated by an internal heat sink, which is supported by the fan at higher temperatures.
