从China供应商批量进口Abb Thyristors

A&S Thyristor Co., Ltd. distributes a full line of ABB power thyristors, including bi-directional controlled thyristors (BCT), gate turn-off asymmetric standard thyristors, fast thyristors, integrated gate-commutated thyristors (IGCT), and GTO thyristors. The catalog spans models such as ABB 5SGA 40L4501, 5STB 24Q2800, 5STP 18H3600, 5STP 45QXXXX, and T989-3300XX, covering voltage classes from 1.8 kV to 4.5 kV and current ratings up to 4500 A, as listed in the supplier’s inventory. Each unit is sourced as original ABB stock, with no aftermarket modifications.

These devices are built on silicon wafer substrates with typical diameters of 100 mm to 150 mm for high-power applications, offering standard blocking voltages in the 2 kV to 6 kV range and typical on-state voltage drops of 1.2 V to 2.5 V. The thyristors are designed for industrial converters, HVDC transmission, and motor drives, conforming to standard IEC 60747 and typical industry practices for thermal cycling, surge current (ITSM), and di/dt ratings. A&S Thyristor Co., Ltd. provides these components in press-pack, module, or stud-base housings, depending on the model.

Industrial buyers use these thyristors in medium and high-voltage drives, static VAR compensators, and traction applications where precise phase control and high reliability are critical. The supplier supports bulk orders and can source additional ABB models on request, with technical data sheets and compatibility verification available. Buyers should confirm exact voltage, current, and switching frequency requirements for their systems, as well as packaging preferences for integration into existing racks or custom assemblies.

A&S Thyristor Co., Ltd. operates from No. 469 Xinsheng Road in Chengdu, Sichuan, China, specializing in the distribution of power semiconductor devices. The company focuses on supplying original thyristors and rectifiers from leading brands, including ABB, GE, Infineon, Mitsubishi, and SEMIKRON, with a catalog that covers both legacy and current models for industrial automation and power conversion applications.

The supplier maintains a harbor trust tier and offers direct access to technical specifications and replacement parts for aging systems. While the response rate and average response time are currently listed as zero, the company states it responds to inquiries within one working day via email. Buyers can request models not listed in the catalog, and the supplier will attempt to source them from its network of OEM partners.
