Thyristors, also known as silicon controlled rectifiers (SCRs), are electronic switches that offer seamless switching between two states. The VS-VSKT105/14 is a standout model of thyristors and is known for its reliability and smooth switching behaviour. This article discusses the VS-VSKT105/14 application field and working principle in detail.

Features

The VS-VSKT105/14 is a module containing sixteen thyristors packed in a single housing. It has a diameter of 4.9 mm and height of 10.5 mm. This module is sufficiently low-cost for industrial applications and uses a single gate for operation. Socket compatible, the module can be directly used on a DIN rail for operation and is also available with insulation sleeves for easier handling and installation. The module provides a surge current up to 16A, a maximum power dissipation of 2.5W and a switching voltage of up to 400V at a maximum of 250mA.

Application Field

One of the primary applications of the VS-VSKT105/14 is that of static switching. It is built to provide a bidirectional, low cost, and reliable solution for static switching applications. The module is suitable for general-purpose switching in household electronics, lighting products, and motor speed controllers. The module can also support high-speed turning on and off with a reduction in electromagnetic interference (EMI). Additionally, the model can be used in solenoid actuation, automotive charging circuits, and general relays for switching purposes.

Working Principle

A thyristor is an electrically activated device that enables the control of current through a single gate. The three terminals of the thyristor are the anode, gate, and the cathode, and once a voltage is applied to the gate, the thyristor switches on, allowing current to flow from the anode to the cathode. An advantage of this model is that it can deliver very low resistance levels, but can also be used to keep a current limit at steady levels. As current passes through the thyristor, it warms up, and the VS-VSKT105/14 features a thermal protection option that can be used to disconnect the thyristor in case the current exceeds the rated value, thereby preventing the device from overheating.

Conclusion

The VS-VSKT105/14 is a reliable, safe, and cost-effective thyristor module with various uses. Its applications include use as a static switcher, motor speed controllers, and general relays. Its low cost makes it ideal for numerous industrial applications. The model\'s single gate operation allows for the easy switching of electricity from one level to another with minimal EMI. Additionally, the thermal protection option provides protection against overheating for current running through the model.
