Thyristors - SCRs - ModulesA thyristor is a solid-state semiconductor device that is made up of two or more alternating layers of P-type and N-type material. A thyristor is part of a larger group of semiconductor devices known as thyristor-controlled modules (SCMs). These SCMs, also referred to as solid state relays (SSRs), are widely used in a variety of applications to control power and voltage. The widely known VS-VSKT162/12PBF SCM is one such module. This article will define the application field and working principle of the VS-VSKT162/12PBF.The VS-VSKT162/12PBF module is an optically-isolated, voltage-controlled, single-phase SSR with a reverse polarity protection feature. Its six terminals (3 anodes and 3 cathodes) are used to control a variety of AC or DC loads, up to 12 Amps of output current. It is designed for use in low-voltage, switched-mode power supply (SMPS) circuits, as well as for AC/DC switchover and motor speed control. The VS-VSKT162/12PBF module works by controlling the flow of current through a switching process in which a thyristor is used to control the voltage and power of a load circuit. When the anode terminals of the module receive a voltage signal greater than the chosen set point, the module’s internal SCR (Silicon Controlled Rectifier) thyristor turns on and relays the voltage signal to the cathode terminals of the module which then turn on the load and supply power. When the voltage falls below the set point, the thyristor turns off and the load is disconnected. This process is repeated until the voltage falls below the set point. The VS-VSKT162/12PBF module can be used in a variety of applications, including in SMPS circuits such as switching DC/AC converters, industrial motor speed control, HVAC systems, and DC power supply systems. In addition, the module can also be used as a solid-state relay (SSR) alternative to electromechanical relays in machines that require precise triggering and voltage control.The VS-VSKT162/12PBF module is designed for use in a wide range of applications. The benefits of using this module include higher reliability, improved design flexibility, greater thermal stability, and increased energy efficiency. In addition, the module is cost-effective and requires minimal maintenance.Overall, the VS-VSKT162/12PBF module is a reliable, efficient, and cost-effective SCM for a wide range of applications. The module uses a thyristor-based switching process to control the voltage and power of a load. The module is designed for use in many applications, including AC/DC switchover, SMPS circuits, industrial motor speed control, and DC power supply systems. Additionally, the module features increased reliability, improved design flexibility, greater thermal stability, and increased energy efficiency.
