Solution description

Remote control for AC fans with 400 VAC motor. The maximum motor current is 8 A. AC fan speed can be selected in 2 - 5 steps via the digital potentiometer with display and key-button interface. The TK monitoring function disables the motor in case of overheating. We advise to limit the cable lenght between potentiometer and fan speed controller.

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 EC fan speed controller is our sophisticated digital potentiometer and HVAC controller designed for precision in ventilation control. Encased in a sleek white housing with a contemporary style, this controller offers versatile functionality to meet your ventilation needs. The enclosure offers both surface and inset mounting options, ensuring compatibility with diverse ventilation setups. In manual mode, effortlessly fine-tune your system using the intuitive 3-button interface. The analogue output is capable of controlling EC fans, AC fan speed controllers, frequency inverters, or damper actuators. Choose between a continuously variable output or segment it into 2-10 equal steps, with adjustable minimum and maximum values to tailor performance to your requirements. For a seamless automated experience, connect a Sentera HVAC sensor to activate automatic mode. The analogue output responds dynamically to ambient temperature, relative humidity, CO2 concentration, air quality (TVOC concentration) or differential pressure. Modify setpoints and parameters easily through the 3-button interface or Modbus RTU communication. This advanced controller operates within a supply voltage range of 110 - 230 VAC, providing flexibility for various applications.
