GE IS200AVGBG1AAA AV300i Gate Driver Board

د.إ8,888.00

GE IS200AVGBG1AAA is a highly specific Printed Circuit Board (PCB) known as an AV300i Gate Driver Board. It’s a critical component within General Electric’s Drive Control Series power electronics, which are integrated with the Mark VI Speedtronic Turbine Control System for high-power applications.

This board does not handle turbine control logic itself; rather, it performs the essential high-speed amplification and isolation required to control the large power semiconductor switches within an industrial motor drive.

⚙️ Core Function: High-Power Switching Interface

The AVGB board acts as the interface and power translator between the low-voltage control circuits of the Mark VI system and the high-voltage power components (the power stack) of a large industrial drive, such as the GE AV300i series.

  • Signal Amplification: It takes the low-voltage, low-current switching signals from the controller and amplifies them into high-current, high-voltage pulses necessary to rapidly and efficiently switch the gates of power devices like IGBTs (Insulated Gate Bipolar Transistors). This fast switching minimizes heat generation (switching losses) and ensures accurate motor control.
  • Protection and Isolation: It provides essential galvanic isolation to protect the sensitive control electronics from the high-voltage noise and transients inherent in the power circuits. It also contains on-board protection logic to guard against faults like overcurrent and undervoltage, which could otherwise lead to a catastrophic failure of the drive.
  • Drive Integration: It’s precision-engineered to match the physical and electrical requirements of the $\text{AV300i}$ drive’s power stack.

🏭 Product Profile and Technical Details

  • Functional Acronym: AVGB (likely derived from $\text{AV300i}$ Gate Driver Board).
  • System Family: GE Drive Control Series, integrated with the Mark VI/VIe platform.1
  • Application: Used in large AC or DC motor drives (e.g., $\text{AV300i}$ drives) that control the speed and torque of equipment like compressors, pumps, fans, or turbine auxiliary motors.
  • Component Type: Normal Assembly PCB ($\text{IS200}$ series).
  • Revision: G1AAA specifies the exact hardware and firmware version. The multiple ‘A’s denote a specific production release, which is critical for ensuring replacement compatibility with the control timing and protection algorithms.

⚠️ Important Considerations for Replacement

  • Revision Match is Crucial: The G1AAA suffix must be matched exactly when replacing the board. Differences in revision can alter timing, signal characteristics, or protection logic, leading to improper switching of the power devices and potential drive failure.
  • Safety Hazard: This board operates in the high-voltage section of the drive. Strict Lockout/Tagout (LOTO) procedures and full de-energization of the drive unit are mandatory before handling the $\text{AVGB}$ board to prevent severe electrical shock.
