NIKON D5300 thyristor module

Product Details Introduction

The SCR Module, also known as the Silicon Controlled Rectifier Module, is an electronic device used to control the current of high-power AC loads. Thyristor modules are commonly used in industrial and high-power applications, such as motor control, electric furnaces, welding machines, electric vehicle chargers, and other fields. They are a semiconductor switching device that allows current to flow through the load as long as they are triggered.

The following are the main characteristics and working principles of thyristor modules:

Main features:

Bidirectional conductivity: Thyristor modules are bidirectional, meaning they can control the current flow on the AC power supply to make them suitable for AC circuits.

Voltage and current levels: Thyristor modules are usually able to withstand high voltages and currents, making them suitable for high-power applications.

Control capability: These modules can be triggered by applying control voltage and allow conduction to be initiated at a certain angle (phase), thereby achieving the start and end of control current.

Over current and over temperature protection: Some thyristor modules have built-in over current and over temperature protection functions to ensure their safe operation.

Reliability: Due to the composition of inorganic semiconductor components, thyristor modules typically have good reliability and long lifespan.

Working principle:

The working principle of the thyristor module is based on the main component called thyristor (SCR) or bidirectional thyristor (TRIAC).

SCR: When a trigger pulse signal is applied to the control end of the thyristor, it begins to conduct current and maintains a conduction state until the current drops to zero. SCR only allows current to flow in one direction and is typically used in single-phase circuits.

TRIAC: TRIAC is similar to SCR, but has bidirectional conductivity and can be used in AC circuits with bidirectional current flow.

The method of controlling a thyristor module usually involves applying appropriate voltage pulses or signals at the control end to initiate conduction and disconnect current when needed. This control can be achieved through microcontrollers, PLCs (programmable logic controllers), or other electronic devices.
