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 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.
