Transformer speed controller TRV0.6

Single phase transformer speed controllers are based on principle of voltage control with auto-transformers. They are applicable to voltage controllable motors for adjusting rotational speed (i.e. fans, pumps, etc.).Controllers have overheating protection function.TRV cotrollers have fan motor thermoprotection connection. These products are designed for simple and cost-effective speed control. The selection of output voltage is done manually with 5 step switch. 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.
