Thyristor power unit

Stepless phase cutting controller for 3~400V/50Hz motors with motor protection.
It has a connection for a potentiometer or an external control signal 0...10V, 0...20mA or 4...20mA.
The control signal can be choosen by an internal jumper. Internal potentiometer for setting set point, min. speed, max. speed and p-band.
Digital input for on/off. Temperature control possible.
Several motors can be connected in parallel as long as the total current does not exceed the current range.
Fans to be used with this controller  should be designed for thyristor speed control.
NOTE: phase cutting controller can make engine noise!
