ABB 5SHX1960L0006

5SHX1960L0006 is an Integrated Gate-Commutated Thyristor (IGCT) module manufactured by ABB, belonging to the high-power semiconductor series. Adopting a modular design, this module enables fast and low-loss switching control under medium-high voltage and high-current conditions. It is widely used in high-power scenarios such as industrial drives, renewable energy inverters, generator excitation, and power systems for large power grids and ships.

Key Technical Specifications

• Rated Current: Can continuously withstand 60 A (specific current depends on supporting components of the 3BHB, 3BHE, and GVC series)
• Peak Surge Current: Approximately 650 A
• Rated Voltage: 1600 V (repetitive turn-off), 1700 V (non-repetitive turn-off)
• Gate Trigger Voltage/Current: 3 V / 200 mA
• Switching Speed: High-frequency switching up to 50 kHz and above
• Operating Temperature Range: -40 °C ~ +85 °C (some models can be extended to -40 °C ~ +85 °C)
• Heat Dissipation Method: Internal heat sink + optional air cooling or liquid cooling, ensuring low on-state voltage drop and low thermal resistance
• Certifications: Complies with international safety standards such as UL and RoHS

Product Features

• High Power and Current Capacity: Capable of switching high currents in medium-high voltage systems, suitable for large motors and inverters.
• Fast Switching: High switching speed reduces switching losses and improves overall system efficiency.
• Low On-State Voltage Drop: Lowers power losses and enhances energy efficiency.
• Modular Structure: Facilitates on-site installation, maintenance, and replacement, supporting hot swapping.
• High Reliability: Excellent thermal stability and electromagnetic compatibility, adapting to harsh industrial environments.
• Multiple Interfaces: Some models are equipped with Ethernet ports, supporting industrial network communications such as 6 channels of 100 Base-T and 2 channels of 1000 Base-FX.

Structure and Composition

• IGCT Main Body: Core semiconductor commutation device responsible for fast switching of high voltage and current.
• Drive Circuit: Includes gate drive and protection circuits, providing precise trigger signals.
• Heat Dissipation System: Combination of internal heat sink and external heat dissipation devices (air cooling/liquid cooling).
• Connection Terminals: High-current terminals and signal terminals, supporting bolt-type or quick-plug wiring.
• Optional Communication Module: Ethernet interface and related protocol stacks, enabling remote monitoring and diagnosis.

Typical Application Fields

• High-power motor drives (e.g., mining, metallurgy, marine propulsion)
• Generator excitation systems
• Medium-high voltage inverters (wind power generation, photovoltaic inversion)
• Power grid regulation and power conversion devices
• High-power switching requirements in industrial automation control systems

Installation Guidelines

• Environmental Requirements: Ensure the installation environment temperature is within the rated range to prevent overheating.
• Mechanical Fixation: Use the installation force (Fm) recommended by the original manufacturer to ensure the module is firmly fixed to the base.
• Heat Dissipation Guarantee: Reserve sufficient heat dissipation space during installation, and install fans or liquid cooling systems if necessary.
• Electrical Wiring: Follow the wiring diagram provided by ABB and use terminals that meet the rated current.
• Communication Configuration (if equipped with Ethernet): Set the IP, subnet mask, and gateway to ensure network connectivity.

Maintenance Recommendations

• Regular Inspection: Check mechanical fasteners and heat sink surfaces for dust or corrosion every 6 to 12 months.
• Temperature Monitoring: Real-time monitor the operating temperature through built-in temperature sensors or external thermocouples to prevent overheating.
• Electrical Parameter Detection: Use professional instruments to detect key parameters such as on-state voltage drop and turn-off time to promptly identify aging or damage.
• Firmware Upgrade (if with communication module): Regularly check the firmware version released by ABB official and upgrade to obtain the latest diagnostic functions and security patches.
• Spare Parts Management: It is recommended to keep spare modules of the same model on-site for quick replacement and reducing downtime.
