| Protection Type | Core Protection Logic | Core Advantages |
| Lock-Rotor Protection | ≤5 times restart with 1s delay, >5 times restart with 30s delay, fault feedback after 90s continuous failure | Avoid burnout due to lock-rotor, automatic recovery to reduce downtime |
| Overcurrent Protection | Instant shutdown when 40A overcurrent occurs, restart with 30s delay, fault feedback after 90s continuous failure | Precisely monitor current, prevent circuit damage from overload |
| Reverse Power Connection Protection | Realized by pure hardware circuit, no current in reverse connection, zero damage to the controller | No worry about misconnection during installation, reduce labor costs |
| Voltage Protection | Shutdown at 16V undervoltage/33V overvoltage, hysteresis zone to avoid boundary oscillation | Adapt to vehicle battery voltage fluctuations for stable operation |
| Overtemperature Protection | PCB shutdown at ≥150℃, automatic recovery at ≤140℃, precise temperature measurement by NTC | High temperature resistant, avoid aging and failure at high temperature |
| Overload Protection | Automatic speed reduction at 18A overload, resume speed after fault elimination | Continuous output without interrupting the vehicle cooling system |
| PWM Signal Abnormality Protection | Maintain operation for 3s then shut down in case of signal loss/short circuit/overfrequency, restart immediately after recovery | No impact on equipment due to signal failure, automatic adaptation and recovery |
| Internal Failure Protection | First 10 times restart with 3s delay, >10 times restart with 30s delay, fault feedback after 10 consecutive failures | Self-diagnosis of component failure, reduce after-sales maintenance |
