What are the functions of the cooling fan? Let's get straight to the topic!

1. SS function

When the cooling fan supplies power to the system, the current will gradually increase from zero until the cooling fan reaches a larger speed ratio and rated voltage, and the larger starting current is the random running current. The centrifugal fan reaches the rated speed ratio within 5 seconds.

2. Cooling fan LP function

The auto-start function ensures that the cooling fan motor restarts automatically to prevent the fan blades from getting stuck. At this time, the cooling fan resets the current to zero, and the cooling fan will automatically start every 3 to 5 seconds.

3. The role of industrial cooling fan FG

This is a collector junction lead output, connected to a "pull-up" resistor and an adapter device to input the operating voltage. The output is a current waveform data signal. The working voltage of the larger collector contact reaches 72V DC, and the current of the larger collector contact is 10mA. The wiring must be connected to the same road location as the cooling fan.

4. DC fan RD function

This is a lead collecting junction function. It has the same hardware configuration function as the above-mentioned FG. When the cooling fan is running, it blocks the fan blades and outputs a pull-up resistor, and then runs to output low frequency.

5. The role of the cooling fan RDB

This is the function of guiding and collecting nodes. It has the same hardware configuration function as the above-mentioned FG. When the cooling fan is running, the fan blades are blocked and output low frequency, which operates as an output pull-up resistor.

6. The role of cooling fan LD

This is the function of guiding and collecting nodes. It has the same hardware configuration function as the FG mentioned above. The basic speed is lower than the output during operation. The alarm starts when the running speed of the cooling fan is lower than 70% of the total target speed ratio.

7. OVP function of cooling fan

This function detects the power supply voltage and the maximum operating voltage that allows the actual operating rating. Generally, the maximum working standard voltage is 20% of the actual working voltage. If the working voltage exceeds 20%, the cooling fan will stop working when the working voltage is exceeded.

8. TC function

This cooling fan must be used. The cooling fan needs temperature control during operation, and the temperature rotates rapidly at a higher speed, but on the contrary, the speed is slower. The three functions of SSCSCL mentioned above are all included.

I believe that after the above introduction, everyone has an understanding of the functions of Ruianpu's cooling fan. If you have any questions, please consult Ruianpu.
