ABB 5SHY2645L0004

Product Overview:
The ABB 5SHY2645L0004 is a Gate Commutated Thyristor (GCT) module, the predecessor to the IGCT. It is designed for high-power applications where the integrated gate drive of the IGCT is not required or where legacy systems are being maintained.

Description

ABB 5SHY2645L0004

Technical Specifications:

  • Device Type: GCT (External gate drive required).
  • Voltage Rating: 4500V – 5500V.
  • Current Rating: 4000A+.
  • Package: Press-pack.
  • Gate: External gate connection.

Functional Features:

  • External Gate: Requires separate, high-power gate drive unit.
  • High Power: Suitable for high-power applications.
  • Robust Design: Built for industrial environments.
  • Legacy Support: Compatible with existing GCT systems.

Application Scenarios:

  • Legacy converter systems.
