VS-16RIA20

Thyristors - SCRs

A Silicon Controlled Rectifier, or SCR, is a solid-state voltage-controlled switch. It is a four-layer, three-terminal electronic device, similar in construction to a thyristor, but with several distinct properties. SCRs are capable of blocking high voltage on the Cathode-Anode voltage side, yet allowing current to flow in only one direction. They are used for power control in circuits ranging from low-power switching operations to high-capacity power sharing networks.

The VS-16RIA20 is a 3-phase, 8A SCR thyristor module rated for use in motor control circuits. It is an integrated AC Motor Control module capable of variable speed and brake control, making it well-suited for use in industrial applications. The module is designed with a high degree of protection against heat and EMC, and is suitable for the most punishing environments.

Application Fields

The VS-16RIA20 is ideal for use in a variety of motor control applications, such as pumps, compressors, and fans. It can be used to control the speed of an AC induction motor. It is also suitable for use in applications as a switching device for high power AC/DC converters, as well as motor-driven hydraulic systems.

The device is well-suited for applications that require precise control over a load, such as in CNC equipment or laser processing machines. Additionally, its protection features make it ideal for use in harsh environments, such as in steel mills or oil refineries. Furthermore, the fact that it supports both local and external control modes makes it well-suited for automated industrial applications.

Working Principle

The VS-16RIA20 is based on the principle of thyristor switching. When the voltage applied to its Gate electrode is increased beyond a certain level, a current is drawn from the anode side, allowing the anode and cathode sides to be connected. This allows current to flow in one direction only, making it an ideal device for controlling the flow of current in a circuit.

The SCR is especially suited for use in motor control circuits due to its ability to block high voltages on the Anode-Cathode side. This feature allows for precise control of the motor and helps to prevent damage to the motor during use. The VS-16RIA20 also features protection features, such as ceramic insulated gate, over-current protection and short-circuit protection, which ensure reliable operation in harsh environments.

Conclusion

The VS-16RIA20 is a 3-phase, 8A SCR thyristor module designed for use in motor control circuits. Its ability to block high voltages on the Anode-Cathode side, along with its overcurrent and short-circuit protection, make it well-suited for use in harsh industrial environments. It is also suitable for use in applications that require precise control over a load, such as in CNC equipment or laser processing machines. The VS-16RIA20 is an ideal choice for applications that require robust power control.
