Product Details
Products Description
What is a centrifugal fan?
A centrifugal fan or centrifugal blower is a pump or motor that moves air. It pulls the air inside the blower and then pushes it out at a 90º angle. The two main components of a centrifugal fan are the motor and the impeller. An impeller sucks or pulls air, in contrast to a propeller which pushes air.
Centrifugal Fan
Additional protection functions can be added: AS automatic lock/start function, slow start function, over current protection,motor lock current protection, reverse connection protection, over voltage protection, PWM, FG, RD, IP55, IP68
FG (speed output signal)
FG function is also commonly referred to as tach out. This function is mainly used to output a square wave signal from the inside of the fan, and the frequency of the signal represents the speed of the fan. Conventional four-stage fan: speed = FG frequency *30. That is, the fan speed can be read by reading the FG signal.
RD signal (stall alarm function)
The RD function is also known as the alarm signal. RD is low when the fan is running and high when the fan is locked. Judge whether the fan is in normal operation or locked state by monitoring the RD signal level.
PWM speed regulation function
PWM refers to pulse width modulation. It means that the frequency (period) of the pulse signal is fixed, and the width ratio (duty cycle: that is, the space ratio) of the pulse wave is changed by the size of the input signal (DC). The on cycle and off cycle of the pulse signal are changed to change the speed of the fan, so as to save energy and reduce noise.
Introduction to waterproof function
1: Glue filling process:IP68 grade The fan runs in water 2 :Vacuum coating process: IP55 – IP68 grade The fan can run with water! The cost is lower than glue filling
