A wireless 3-phase FFU control equipments is provided to determine motor operation by controlling on/off of a pan filter through a wireless command packet. A DC power supply unit(100) converts AC voltage applied from an AC power supply unit into DC current voltage and outputs the converted DC voltage. A power control unit(500) receives AC power and supplies an electric motor operation control signal to the electric motor. A wireless communications unit(900) transmits the electric motor operation control signal through a wireless command packet. The controller(300) receives a driving power from the DC power supply unit and transmits received electric motor operation control signal to a power control unit. |
