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.
