3. The Electrical Protection Function
| Lock Protection |
|
|---|---|
| Polarity Protection | Open circuit when Vcc & GND are exchanged |
| Over Current Protection | NO |
| Fixed Constant Speed Function | NO |
| Soft Starting | When the power switch is turned on to supply current to the fan, the current is zero and starts to increase gradually until the fan has achieved its maximum speed and the rated current. |
| PWM Function | Enter a PWM duty cycle signal to control fan speed |
| Hot plug | No |
