Schematic overview
400 V motor 9,5 A | air quality control | air ducts
Solution description
TVOC based fan speed control for AC fans with three-phase 400V motor. The maximum motor current is 9,5 A. AC fan speed is automatically controlled based on the air quality (TVOC level) in the air duct. The TVOC range and all other parameter settings can be adjusted via Modbus RTU communication. The temperature of motors with temperature sensor (TK or PTC) is monitored. In case of motor overheating, the motor is disabled to prevent damage. A start-stop command can be generated via an external switch (option).
