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.
