Thyristors are solid-state semiconductor switches that have three terminals. One of the main applications of Thyristors is power control, meaning controlling the amount of voltage and current that a device receives in applications such as lighting control, motor speed control, HVAC systems, and audio power amplifiers. The VS-VSKT71/08 is a popular Thyristor/SCR Module used in various industrial applications. This article will discuss its application field and working principle.

Application Field

The VS-VSKT71/08 is a three-terminal semiconductor module with a maximum DC blocking voltage of 1000 volts. It is a bidirectional control device suitable for AC control of power switching and resistance load applications. It combines a sensitive, bidirectional current sensing SCR with an integrated logic controller to provide fast and accurate control of the load current over a wide range of DC and AC parameters. The VS-VSKT71/08 has an operating temperature range of -65°C to +175°C, making it suitable for many environments and applications. The module is suitable for use in a variety of industrial and consumer markets, including automotive, communications, commercial, medical, and others.

Working Principle

The VS-VSKT71/08 module operates as an overcurrent protection circuit. It has three terminals, a main terminal (MT) and two sense terminals (ST1 and ST2). The module senses the voltage across the ST2 terminal and compares it to a reference voltage. If the voltage reaches the reference voltage, a signal is sent to the main terminal. This signal causes the SCR to turn off, and the current is stopped.

The VS-VSKT71/08 is designed to provide fast and accurate control of the load current in response to varying DC and AC parameters. It is inherently insensitive to changes in the voltage across the ST2 terminal, making it suitable for AC applications. The module is capable of controlling the load current accurately and quickly over a wide range of AC and DC parameters, allowing it to be used in a variety of industrial and consumer applications.

Conclusion

The VS-VSKT71/08 is a popular Thyristor/SCR Module used in many industrial and consumer applications. The module is designed to provide fast and accurate control of the load current in response to varying DC and AC parameters. It is ideal for power control applications such as lighting control, motor speed control, HVAC systems, and audio power amplifiers. Thanks to its low on-state voltage drop, fast switching speed, and reverse- blocking capability, the VS-VSKT71/08 is perfect for a variety of applications.
