Voltage Controller TM3-4

This controller is suitable for voltage-regulated 3-phase motors and can be manually operated with a switch (setting 0 to 5) on the housing.

The controller will shut down after:

thermal triggering of the motor (fan) thermal triggering of the transformer protection after power failure Then reset the controller by setting the switch to the zero position.

A tap transformer (in open V configuration) determines the voltage in each position.

Check if the fan is voltage-regulated.
