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. |
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. |
