Schematic overview
3 phase 230 V motor 7 A | air quality control
Solution description
TVOC based fan speed control for AC fans with three-phase 230V motor. The maximum motor current is 7 A. AC fan speed is controlled automatically to keep air quality (TVOC), temperature and relative humidity in range. The ranges can be adjusted via Modbus RTU communication. In case the motor is equipped with a temperature sensor (TK or PTC), the motor temperature can be monitored. In case of overheating, the motor is disabled to prevent damage.
