CO control - AC induction motor


This solution controls AC fans with single-phase motor. The maximum motor current is 10,5 A. The fan speed is controlled in function of CO concentration. The CO setpoint can be adjusted via the key button interface of the frequency inverter. The infinitely variable speed control guarantees smooth motor operation. The CO sensor allows flush mounting or surface mounting. With this solution, it is also possible to fan speed in function of temperature or relative humidity. If the motor is equipped with thermal contacts (TK or PTC), the frequency inverter can detect motor overheating in an early stage and disable the motor to prevent damage. The frequency inverter enclosure is dust tight and ready for washdown duty.
