400 V motor 8 A | Remote fan speed control | display

This transformer controller has an analog input of 0-10 V. It controls a 400 volt three-phase motor. The (combined) maximum motor current is 8 A. The speed is regulated by reducing the motor voltage in 5 steps using autotransformer technology. One of these 5 levels is selected by an analog control signal (0-10 volts) or an external potentiometer. The fully sinusoidal output voltage guarantees silent operation of the motor. The TK monitoring function turns off the motor in case of overheating. The IP54 metal enclosure can be surface mounted. The supply voltage is 400 V AC.

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.
