Thyristors - SCRs - Modules

Silicon Controlled Rectifiers (SCRs) are the most commonly used type of thyristors. The B512FSE-2T-YEB is a robust and reliable SCR module designed for a variety of applications. It is capable of providing high electrical and thermal protection in challenging environments, such as harsh industrial and high-temperature environments.

The device is designed as a dual-channel SCR module, consisting of two vertically stacked SCRs housed in a low-profile, plastic or metal enclosure. The SCRs have a nominal blocking voltage of 1200V, a trigger current of 2mA and an ultimate on-state current of 15A. The device is also equipped with a LED indicator to indicate a successful SCR firing.

The B512FSE-2T-YEB is designed for use in various industrial, automotive, and consumer application fields. In automotive applications, it is especially suitable for automotive engine control, idle speed control, and cruise control systems. It can also provide excellent protection from overloads and short circuits in industrial and consumer applications such as welding and lighting systems.

The B512FSE-2T-YEB works by controlling the flow of current after the threshold voltage is reached. When the voltage reaches the threshold level, the LED indicator lights up and the SCRs open. This process allows the current to flow from the negative side of the battery through the SCRs, then to the electrical load, and finally to the positive side of the battery. The device is designed to operate in such a way that the peak current is limited by the SCRs and not by the battery.

To ensure reliable performance, the device is designed with a variety of protection features, such as overcurrent protection (OCP) and overvoltage protection (OVP). The OCP feature limits the maximum current that can flow through the device, while the OVP feature limits the maximum voltage that can be applied to the load. This helps to protect the device from short circuits and protects the load from overvoltage conditions.

The device can also be used in DC applications, such as DC motor speed control, AC-DC converters and DC induction motors. In these applications, the device can be triggered by a signal generated by a controller. The controller will measure the speed of the motor and send a signal to the device when the speed needs to be adjusted. The device will then open or close the SCRs and adjust the speed of the motor accordingly.

The rugged construction and high level of performance provided by the B512FSE-2T-YEB make it an excellent choice for a variety of industrial and consumer applications. Its high level of protection and precise current control make it ideal for demanding applications such as automotive engine control, idle speed control, and cruise control systems. In addition, its ability to operate in both AC and DC applications makes it suitable for use in a wide range of applications.
