Transformer controllers are designed to change motor rotating speed by changing voltage. All controllers have thermo protection function. Controllers have two control knobs: one for higher fan speed and one for lower fan speed. Switching between the high and low settings is done by an external change-over contact, which could be a time relay or other device. Fixed voltage steps can be switched with two rotation switches. Controller is reset by turning the switch to "0" position for 10 seconds, after which unit restarts. RT2r controllers have voltage indication lamps. All controllers have thermo protection function. All controllers have 230 VAC output for connection of servo motors, actuators, heaters relays and etc.
