EduTrainer® load resistance

EduTrainer® load resistance

Nou 

The load resistance is used to load electrical machinery for use as generators or as starting resistors for slip ring rotors.

It consists of a rheostat with an upstream protecting resistor. An additional fixed resistor can extend the load range. 

The rheostat is infinitely adjustable; the multi-level winding allows different maximum peak currents to be set as loads.

The 3-phase rectifier allows the load resistance to be used as a load for alternating and 3-phase current sources.

All connection locations are standardised and are laid out as safety sockets.
