The GVC704AE01 3BHB003023P201 is an industrial-grade Integrated Gate-Commutated Thyristor (IGCT) module. As a core power component of ABB's medium and high-voltage power electronic equipment, it combines the high voltage resistance and high current characteristics of IGCT devices with the flexibility of modular design. Its core function is to achieve efficient conversion and precise control of electrical energy: it can not only adapt to medium-voltage frequency converter systems to complete AC-DC conversion, but also serve as a current control unit for high-power equipment. It is widely used in medium and high-voltage scenarios such as industrial motor drives and energy transmission, and is a key power electronic component for ensuring the stable operation of high-power equipment.

Electrical Performance and Device Characteristics

IGCT Core Parameters

• Rated Voltage: Suitable for medium-voltage scenarios, with a typical value of 6.5kV (in line with medium and high-voltage industrial standards), and can withstand instantaneous overvoltage up to 8kV.
• Rated Current: Continuous current-carrying capacity ≥ 1.2kA (effective value), peak current ≥ 3kA, meeting the power supply requirements of high-power equipment.
• Switching Frequency: Adaptable to 50-60Hz power frequency, with low switching loss and conversion efficiency > 95%, reducing electrical energy loss in industrial scenarios.
• Control Signal: Supports DC 24V gate control signal, with a response time ≤ 10μs, enabling rapid current adjustment and fault shutdown.

Protection Functions

• Integrates triple protection: Overcurrent Protection (OC), Overvoltage Protection (OV), and Over Temperature Protection (OT). When abnormal current/voltage is detected or the module temperature exceeds 85℃, it automatically cuts off the output to protect downstream equipment and the module itself.
• Has reverse current blocking capability to prevent device damage caused by reverse current impact under fault conditions.

Structural Design and Environmental Adaptability

Physical Specifications

• Dimensions: 280mm × 180mm × 65mm (length × width × thickness), adopting a compact package, suitable for installation in standard industrial cabinets and medium-voltage frequency converters.
• Weight: 2.8kg, with a built-in copper-based heat dissipation substrate and heat dissipation fins to improve heat conduction efficiency.
• Interfaces: Uses bolt-type power terminals (suitable for copper bar connection) and plug-in signal terminals to ensure the firmness of power connection and stability of signal transmission.

Environmental Tolerance

• Operating Temperature: -25℃ ~ +70℃ (wide-temperature design, covering industrial workshops in frigid zones to high-temperature production environments).
• Storage Temperature: -40℃ ~ +85℃, humidity 5% ~ 95% (non-condensing), adapting to high-humidity and extreme temperature difference scenarios.
• Vibration Resistance: Complies with IEC 60068-2-6 standard (10-500Hz, acceleration 20m/s²); impact resistance complies with IEC 60068-2-27 standard (peak acceleration 50m/s²), suitable for scenarios with frequent vibration such as mining and metallurgy.
