Three phase transformer fan speed controllers
Three-phase transformer fan speed controllers are based on the principle of voltage control with autotransformers. Manually you could control the fan in 5 steps with a rotary switch. With one-speed controller it is possible to control several motors if the sum of currents of all motors does not exceed the maximum current of the speed controller.
Transformer fan speed controllers | Maximum current 12 A
Three phase transformer fan speed controllers TTS series let manually control the fan speed in 5 steps: 0-95-145-200-280-400V. Fan speed is controlled from minimum to maximum (from low to high speed). TTS series controllers have the possibility to monitor fan thermal contacts TK. When the fan is overheating, the controller stops the fan and starts again when the problem is solved. It is needed to turn on 5 step switch to position 0 and turn it on again. These transformer fan speed controllers' enclosures are made from metal sheets and have a maximum current of 12 A.
