MCC95-12IO1B

MCC95-12IO1B is a type of semiconductor module which is based on power thyristor SCR technology. This product simplifies the design of power applications and offers a dependable performance and minimal system overhead.

Application Field

The MCC95-12IO1B module provides control and protection of power conversion and rectifying circuit topologies in a single unit. Application fields include motor drive, lighting, rectifiers, welding, uninterruptible power supply, and other power electronic components that require fast thyristor switching, such as industrial, medical, aviation, and military applications.

Working Principle

The MCC95-12IO1B module consists of four SCRs arranged in an inverse parallel configuration. These four independent thyristors provide bidirectional overvoltage protection and inrush current limiting capabilities. The unit offers superior overtemperature protection and controlled surge characteristics to maximize efficiency and alleviate potential overheating.

The unit can be triggered with a nominal DC voltage between two terminals, or an AC voltage can be applied directly to two of the four terminals. These two types of triggering provide flexibility in controlling thyristor activation. Once triggered, the circuit will continue to conduct current until the current flowing between two terminals drops to the given minimum or until a specified time interval has lapsed.

This semiconductor module is well-suited for switching between loads of varying DC voltage levels, particularly for dynamic motor speed control applications and other critical industrial applications. Because the module can accommodate a wide range of voltages, it provides an efficient and highly reproducible switching mechanism even under challenging conditions.

Conclusion

The MCC95-12IO1B module is a valuable addition to power electronic design solutions. It offers a reliable solution for controlling and protecting thyristor rectifier circuits and provides a robust, cost-effective solution that can meet a wide range of industrial needs.
