QJE 0-30V / 20A Switching mode power supply

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.
