* For Example : moisture roof, water proof, turbocharger, soft start, Reversible, temperature control, PWM speed control, the RD
alarm and the FG signal etc.
*IP 55: Protection of motor and PCB board against splashed water and humidity.
*Speed signal: The fan uses a separate wire to output information about its speed, and thus about the speed of the rotor.
*PWM control input: The speed of the fan can be changed via a pulse-widthmodulated signal. This signal is applied to a specially
provided wire.
