TGRV

Transformer controllers are designed to change motor rotating speed by changing voltage.

 

Transformer controllers TGRV are designed to change motor rotating speed by changing voltage. All controllers are with motors and transformers thermo protection function. Steps are with fix voltage and are changed with rotary switch. Controllers also have power indication led. All controllers have 230 VAC output for connection servo motors, actuators, heaters relays and etc. To one controller more than one motor can be connected, if total current of all controllers is less than maximum controller current. In this case all motors thermo protections must be connected in series.
