400 V motor 4 A | Remote fan speed control | display

This transformer controller has a 0-10V analog input. It controls a three-phase 400 volt motor. The (ombined) maximum motor current is 4 A. The speed is regulated in 5 steps by reducing the motor voltage via autotransformer technology. One of these 5 levels 1 is selected by means of an analog control signal (0-10 volts) or an external potentiometer. The full sine output voltage guarantees the quiet operation of the motor. The TK monitoring function deactivates the motor in case of overheating. The IP54 metal casing can be surface mounted. The supply voltage is 400 VAC.

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.
