Student power supply AC/DC (non-stabilised)
2-12 V AC / DC in 6 steps

The student power supply unit AC / DC (non-stabilised) 2-12 V AC / DC in 6 steps is a handy and easy-to-use power supply unit for use in class. It can be used to generate a smoothed non-stabilised DC voltage of 2 V, 4 V, 6 V, 8 V, 10 V and 12 V. It supplies a continuous current of 4 A at all DC output voltages, which may also rise to 5 A for short periods. Above 5 A, there is a cut-off.

Alternatively, the voltage can be tapped as a pure sine wave voltage, bypassing the rectifier and the smoothing capacitor.

A safety transformer is used in the student power supply unit. The design prevents pupils from coming into contact with live components through the ventilation openings - even with pointed objects. live components - even with pointed objects. The sockets are designed as safety sockets. Experiment cables with 4 mm safety plugs as well as those with 4 mm banana plugs can be used.

The output voltage can be fixed at a preset value using a long hexagon socket screw and a suitable hexagon socket spanner (both included in the delivery). value. It is not possible to adjust the output voltage, as the step switch for the output voltage is mechanically blocked. This prevents damage to the This prevents damage to the experimental setup due to an impermissibly high output voltage.
