Introduction

T9S7321403DH is a SCR module manufactured by TECON Electronics Co. Ltd. SCR stands for Silicon Controlled Rectifier, and it is a type of thyristor. A thyristor is a three-terminal semiconductor device, which can be used as either an on-off switch or a rectifier in various applications.

Application Field

T9S7321403DH thyristors find their application in a variety of fields, such as motor control, power electronic converters, UPS systems, AC motor drives, and other applications where high current or voltage needs to be switched at a high frequency. It is used for power supply and switching applications in high voltage and high power systems. This module is also widely used in industrial automation and equipment, for controlling motors, pumps, fans, air compressors and other machinery.

Working Principle

T9S7321403DH thyristor module is based on the principle of the gate controlled switch. A thyristor module consists of two thyristors connected in inverse parallel with each other. The gate current is first applied to one of the thyristors, then to another one due to the inverse parallel connection. The thyristors are turned on when the voltage across their gate terminals reach the gate trigger voltage. The thyristor module is controlled by the gate current, and when the current is applied to the gate, the thyristors are turned on. The thyristors are turned off by removing the gate current.

The T9S7321403DH thyristor module is primarily used for chopper applications, where a large amount of current is required to be switched from one DC source to another. Choppers are used to store and release electrical energy in the form of pulses, and thyristor modules provide a reliable way to achieve this. The thyristor module is also used in AC motor speed control , where it is connected to the motor’s stator windings in order to control the motor’s speed.

T9S7321403DH is a high power thyristor module, with a maximum voltage rating of 2,600V and a maximum current rating of 600A. The module is designed to provide a low on-state voltage drop, and a very high surge current carrying capacity. It also has a very fast switching response time, making it suitable for applications that require high speed switching.
