Key Features

 

 

An additional wire is offered to output an oscillating voltage output which can be usedby the system to infer the fan speed

 

 

 

 

An additional wire is offered to output a voltage signal when the fan is stationary . itis a useful functionality to identify non-operating fan.

 

 

 

The speed of the fan can be controlled via a pulse-width-modulated (PWM) signalcarried by a dedicated input wire.

 

 

 

The fans are designed to offer protection against dust and water. The digits behindthe letter lP indicate different levels of protection.

 

 

 

A NTC thermistor is connected to the fan and the fan speed varies with thetemperature measured by the thermistor.

 

 

 

The speed of the fan can be controlled via a voltage signal carried by a dedicatedinput wire.
