Thyristors - SCRs - Modules

Thyristors,which are also known as SCRs (silicon controlled rectifiers) are solid-state electronic components for controlling electrical currents. They are widely used in power control applications in many different industries such as, lighting, motor drives and power supplies. Modules are integrated circuits that contain multiple SCRs and diodes connected in a single package. C784DA is a module which contains three SCRs that are connected in parallel configuration.

Application Field of C784DA

The C784DA module is predominantly used in power control applications such as lighting control, motor speed controllers and AC power controllers. It is used to regulate high voltage and current levels with the purpose of controlling the power delivered to an electrical device. For this reason, the C784DA module is typically used in applications that require high power loads or a large amount of input current. It is designed to switch between two states quickly and efficiently, meaning that it is suitable for applications where the power cycling needs to be done in a short amount of time. It is also used to replace AC line switches for applications that require control of alternating current. In addition, the C784DA module is also used for temperature control. As it is capable of switching between two states quickly, it can be used to monitor the temperatures of various components and switch the power supply on and off as required to maintain a desired temperature.

Working Principle of C784DA

The C784DA module works by switching DC voltage between two levels with fast response to input signals. It is made up of three silicon controlled rectifiers (SCRs) connected in parallel. This arrangement provides a very small junction capacitance, making it suitable for switching high voltages and currents quickly.Each SCR has two terminals for controlling the amount of current that flows through it. The SCRs are connected so that when the input voltage across the two terminals reaches a certain level, the SCRs switch from their open-circuit state to the closed-circuit state and the current starts flowing. This process is known as triggering the SCRs.Once the SCRs are triggered, they remain in the closed-circuit state until the input voltage falls below a certain level or the SCRs are turned off. In this way, the C784DA module works as an AC power switch and it is able to quickly switch between two levels of DC voltage. This makes it well-suited for applications requiring a fast response time. The C784DA module also has a built-in under voltage protection, meaning that the module will not switch on until the input voltage reaches a certain level. This sets a maximum level of input voltage and helps to prevent overvoltage from damaging the module.

Conclusion

The C784DA module is a powerful switch for switching DC voltage between two levels with fast response to input signals. It is a solid-state electronic component made up of three SCRs connected in parallel and is predominantly used in power control applications. The C784DA module is well-suited to applications requiring a fast response time and is also useful for applications requiring temperature control and for switching AC line switches.
