　　Response Time: ≤25ms, ensuring fast voltage stabilization.

　　Cooling Method: Uses a closed-loop water/air cooling system with redundant pump design, maintaining module junction temperature ≤100℃. Protection and Certification:

　　IP54/IP65 protection rating, suitable for harsh environments (high temperature, high humidity, vibration).

　　Certified by CGC (GB/T 25387-2010) and DNV-GL (GL-IV-2:2012), and complies with standards such as IEC 61800 and GB/T 12668.

　　Modular design: Supports quick replacement; integrates power management, grid synchronization detection, and circuit breaker control, compatible with the modular architecture of the PCS6000 system.

　　Application Scenarios and Industries

　　Wind Power: As a key component of full-power converters (e.g., PCS6000), used in onshore/offshore wind turbines for low-voltage ride-through, dynamic braking, and grid synchronization.

　　Industrial Drives: Used in high-power drive systems for steel mills, mines, cement plants, etc., ensuring safe start-up and shutdown of high-voltage motors and enabling energy recovery.

　　Power Grid Support: Provides reactive power compensation, harmonic suppression, and voltage stabilization in Static Synchronous Compensators (STATCOM).

　　Special Environments: Customized weatherproof models are required for high altitude, high humidity, and low-temperature areas (e.g., Northeast China, Tibetan Plateau).

　　Installation and Maintenance Guidelines

　　Installation Standards:

　　Mechanical Installation: Use flange or threaded fasteners; ensure sufficient access space (≥1.5m in front, ≥0.8m behind); avoid damp/corrosive environments.

　　Electrical Connections: Correctly connect DC bus positive (+) and negative (-) terminals; use ≥4mm² cross-section wire, ≤5m length; ensure reliable contact.

　　Heat Dissipation: Maintain ≥30cm spacing between braking resistors and units; vertically mount on a metal frame; avoid heat radiation affecting nearby components.

　　Location: Keep away from sensitive equipment; ensure good heat dissipation (e.g., roof/underside mounting); implement EMC shielding.

　　Wiring: Use low-impedance cables; meet voltage/current capacity requirements; connect to a thermal switch for overtemperature protection.

　　Safety: Enable Safe Torque Off (STO) function to prevent accidental start-up; power off and discharge residual voltage during maintenance.

　　Overvoltage Protection: Enable braking resistor thermal switch; set overload protection parameters (e.g., 43.08/43.09) to prevent resistor burnout. Electromagnetic Compatibility: Utilizes a symmetrical cable structure and grounded shielding, complying with IEC61373/GB/T21563 vibration and shock standards.

　　Compliance: Meets IEC60322/GB/T25118 insulation standards and EN15085 welding specifications, ensuring device safety certification.

　　Maintenance Requirements:

　　Regular Inspection: Monthly verification of secure wiring connections, resistance surface integrity (no burn marks/cracks), dust removal, and insulation resistance test (≥100MΩ @500VDC).

　　Parameter Settings: Adjust the operating voltage (typically 1.15 times the motor rated voltage) and braking cycle (continuous/pulse mode) via the inverter parameter group (e.g., "31 Braking Control").

　　Troubleshooting: Check threshold settings if the braking unit fails to operate; verify power matching if the resistor overheats; check the IGBT module and driver circuit for abnormal alarms.

　　Application Scenarios:

　　Rail Transportation: Dissipates kinetic energy during braking in high-speed trains and subways, preventing grid voltage fluctuations.

　　Industrial Drives: Rapid braking for cranes, fans, and pumps, reducing mechanical impact.
