3.Electrical Protection
3-1 | Locked-rotor Protection | Over-current limiting circuit protects motor from damage at least for 72 hours oflocked rotor condition at rated voltage. |
3-2 | 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. |
3-3 | Reverse Polarity Protection | No damage if the positive and negative leads are reversed under maximum operation voltage conditions. |
3-4 | Over Voltage Protection | lhe circuit will be shut down automatically when input voltage over 30VDC.And re-started when Voltage down to 30VDC below. |
3-5 | Soft Start | In 5 seconds after power on and speed control voltage gets to 1.5v. |

9.Safety Requirements
1. Make sure that the metal casing of the stator connected to the ground before being powered on.
2. If the fan doesn’t work after been powered on, please check the speed control input voltage, it may not be well connected. To prevent the suddenly start of the fan to hurt hands or other personal injury; do not touch the impellers or rotor when the power is on.
3. Fan needs a few seconds to start after being powered on. To prevent personal injury, do not touch the impellers or rotor when the power is on or in a low speed.
4. Unless they are instructed by the person(s) responsible for their safety, those who are lack of physical, mental or sensory capacities and proper practical experience or expertise cannot use this appliance. Please do not let the children play with this product.
5. If the power cord be damaged, the power cord must be replaced by the manufacturer in order to avoid accident of the proxy service personnel or the equivalent qualification maintenance personnel.
6. As an integral part of the fan, this DC motor cannot be used alone without impeller or load.
7. Please carefully read this technical specification before using the product.
