3. Electrical Protection
Locked-rotor Protection
Over-current limiting circuit protects motor from damage at least for 72 hours of locked rotor condition at rated voltage.

Maximum Current
under Locked Rotor
A, Typical inrush current when the motor is trying to re-start under locked rotor conditions is 2~4 times the normal running
current reoccurring and for 16~20% of restarting cycle period.
B, If he CL function is used this restarting inrush current is about the same as the normal running current.
Reverse Polarity Protection
No damage if the positive and negative leads are reversed under maximum operation voltage conditions.
Over Voltage Protection
The circuit will be shut down automaticlly when input voltage over threshold. And re-started when Voltage down to threshold below.
Soft Start
In 5 seconds after power on and speed control voltage gets to 1.5V or PWM duty cycle at 10% above.
