400 V motor 1,5 A | Remote fan speed control | display

This transformer controller has an analogue input ranging from 0 to 10 V. It controls three-phase 400 volt motors. The maximum motor current (combined) is 1,5 A. The motor voltage is reduced in five steps to manage the speed using autotransformer technology. An analogue control signal (0-10 V) or an external potentiometer is used to pick one of these five levels. A precise sinusoidal output voltage ensures silent motor running. If the TK monitoring feature detects overheating, it shuts the motor. Surface mounting is possible with the IP54 enclosure. The power source voltage is 400 VAC.

The RDCV fan speed controller is a digital potentiometer for residential ventilation applications, designed for precise and flexible control. It features a modern design with an intuitive three-button interface and a LED display. The controller is suitable for operating EC fans, AC fan speed controllers, frequency inverters, and damper actuators. Fan speed is manually adjusted via a simple three-button interface and the output can be continuously variable or divided in 2 to 10 equal steps, with adjustable minimum and maximum values. The controller supports Modbus RTU communication and operates on a supply voltage of 110 to 230 VAC. The modern white enclosure supports both surface and flush mounting. RDCV offers a versatile solution for modern ventilation systems that require accurate control and flexible installation options.
