VS-ST173C10CFK0

Thyristors - SCRs (Silicon Controlled Rectifiers) are a type of three-terminal semiconductor switches that control the flow of electricity in one direction. The VS-ST173C10CFK0 is a three-phase Thyristor module with 700 volts and a forward current rating of 10A. This type of Thyristor module allows for the efficient and cost-effective control of electrical current in industrial applications. The VS-ST173C10CFK0 is typically used to rectify and regulate electrical currents in three-phase AC circuits. It is especially useful in applications such as motor drives, induction heaters, and motor control. The module features built-in over-voltage protection, enabling it to handle high voltages without damage.The working principle of the VS-ST173C10CFK0 is based on a voltage-controlled switch. When a voltage of less than 0.6 V is applied to the gate terminal of the module, the Thyristor is blocked and no current flows through it. When the applied voltage is between 0.6 and 1.2 V, the Thyristor is triggered and current flows. The Thyristor remains in the triggered state as long as the current flow is greater than the hold current, even after the gate voltage is removed. The module has a number of other helpful features, such as a built-in diode that prevents backflow and a thermistor that quickly shuts off high currents. In addition, the device includes precise current balancing between the main contact and the protector contact, enabling precise and efficient current control.The VS-ST173C10CFK0 is a reliable and efficient device for industrial applications, as it can accurately and consistently control currents up to 700V in three-phase AC circuits. Its two built-in protective features, the diode and the thermistor, make it especially suited for applications that require precise, high-reliability current control such as motor drives and induction heaters.
