VS-P424

VS-P424 is a kind of three-phase direct thyristor unit, which adopts two thyristors connected in anti-parallel as the main components. It is mainly used as AC static switch unit, rectifier, inverter, converter and frequency control device in low voltage AC drive and power control system such as locomotive, industrial control and stabilizer. VS-P424 has the characteristics of small volume, high reliability, wide control range and fast dynamic response.

Application Field

VS-P424 is mainly used in applications such as locomotive, industrial control, stabilizer, frequency control device and other power control systems. It is mostly applied in AC dynamic switch, micro-adjustment, AC drive, power adjustment, stepless speed regulating, dynamic voltage adjustment and other fields.

VS-P424 also has better synchronous performance, resulting in improved cost and control accuracy. AC drives enable smooth and continuous control of various industrial processes, power and energy saving. Apart from being used as AC static switch unit, it can also be used to start AC motor, absorb energy or store energy.

Working Principle

VS-P424 can be used to control the movement of AC power and has a power control circuit composed of two thyristors connected in anti-parallel. The thyristor will be triggered when there is a current exceeding a certain value in the circuit, causing the thyristor to be in its conduction state. The characteristics of thyristors also have a certain time requirement, making it possible to control the normal operation of AC current.

When VS-P424 is triggered, the current will go through one of the thyristors, which will become in its conduction state and the current flows normally through the thyristor, resulting in the thyristor in its non-conductive state. After the current drops to a lower level, the reverse current will flow between two thyristors, causing the second thyristor to be in its conduction state, completing a power control cycle.

Conclusion
