TGRT Three-phase speed controller
Transformer speed controllers TGRT operate on the principle of voltage regulation using an autotransformer. The regulators are adapted to regulate the speed of adjustable voltage motors (~ 3f, 400V / 50Hz).
All regulators contain a thermocontact that protects the motor from overheating.
