LDR31654 Discrete Semiconductor Products

Tyristors - SCRs - Modules

The LDR31654 is a module which uses thyristors to control electrical circuits. It is part of the family of SCRs (silicon-controlled rectifiers), which are commonly used for controlling electrical circuits. The module provides features such as voltage and current control, as well as short-circuit protection.

Application Field

The LDR31654 is commonly used in a variety of applications, such as motor control, lighting control, and switching power supplies. Due to its voltage and current control capabilities, it is also used to regulate outputs of other components, such as sensors or other electronics. It can be used as a single control module in closed-loop systems, or can be connected to multiple modules for larger applications.

Working Principle

The LDR31654 works on a simple principle, known as the four quadrant gate control. When the module is activated, the voltage generated from the control source is conducted through the gate of the thyristor. This causes the thyristor to conduct immensely, which in turn transfers the control source voltage to the output of the module. As the thyristor conducts, it allows the current to flow through the circuit, thus controlling the voltage and current outputs of the circuit.

The module is also capable of providing short-circuit protection. When a short circuit is detected, the module trips the thyristor, which causes the voltage and current outputs to go to zero, thus preventing any further damage to the circuit.

Conclusion

The LDR31654 is a versatile module, with numerous applications. It is commonly used for motor control, lighting control, and switching power supplies, but can also be used for other applications. It provides voltage and current control, and can also protect a circuit from short-circuits. With its simple operation and robust design, it is the perfect choice for a wide range of electrical control applications.
