  • Product description
  • Product features
  • Technical specifications
  • Product size
  • QYTSC series contactless switch (pure silicon controlled rectifier) consists of high-power anti parallel thyristor module, photoelectric isolation circuit, trigger circuit, protection circuit, heat dissipation device, etc. It is used for on-off control of capacitive load of low-voltage 400V system, without impact inrush current, overvoltage and noise during operation. It is especially suitable for supporting fast switching and SVC low-voltage dynamic reactive power compensation device.
