RTS Series - Overview
Three phase transformer speed controllers are based on the principle of voltage control with auto-transformers. They are applicable to voltage-controllable motors (400 V, 50/60 Hz) to control the speed (of fans, pumps, etc.) thereby reducing the air flow and noise of the fan. They are fitted out with (TK) contacts for thermal motor protection.
Several fans can be connected to controllers considering only that the total current of all motors should not exceed the nominal current of the controller.
