Operation and Maintenance Recommendations

Installation Notes

Electrical Connections: Ensure firm wiring and correct polarity to avoid parasitic inductance in high-current loops.
Heat Dissipation Installation: Apply thermal grease between the module and radiator to ensure good contact; ensure sufficient air volume in air-cooling systems and prevent water leakage in water-cooling systems.
Insulation Protection: Implement adequate insulation measures in high-voltage environments, using suitable insulating materials and spacing.

Parameter Configuration

Set trigger pulse parameters (such as trigger delay angle and pulse width) through the supporting drive circuit to ensure reliable thyristor conduction.
Integrate with control systems (such as PLCs, DSPs) to achieve real-time monitoring and protection logic.

Maintenance and Fault Diagnosis

Regularly inspect the module's appearance for cracks, burns, or overheating marks.
Measure the resistance between pins (with power off) and compare with normal parameters to determine if the chip is damaged.
In case of faults (such as overcurrent tripping), troubleshoot external circuits (e.g., load short circuits, abnormal drive signals) and check if the module needs replacement.
