3.Fan spare parts
Besides of DC/AC/EC cooling fan, we also produce fan guard, it can be combined with fan to dust-proof.
4.Function options
● RD(rotation detector/alarm signal output) :
When the fan operates normally, the RD signal output with low-level, but when the fan leaves are locked, the RD signal output with high level. Client can check the RD signal with low or high to see that the fan is working properly
● FG(frequency generator/tachometer output):
By reading the frequency of the signal, the fan speed can be know
● PWM(Pulse Width Modulation):
The PWM function fan is a square wave signal with adjustable duty cycle input from external equipment.
The internal circuit of the fan automatically adjusts the speed of the fan according to the duty cycle of the input signal and enters the outside.
The device can test the speed by reading the FG frequency of the fan.
