In terms of its application field, this device is mainly applied in areas such as industrial computer control, medical electrical equipment, telephone, military equipment, and other industries.

Working Principle of VS-VSKK230-12PBF

The VS-VSKK230-12PBF is a three-phase SCR module, which consists of three SCRs connected in an anti-parallel manner. Each of the SCRs is provided with an anode and a cathode, and the module is provided with an auxiliary gate (G1/G2) and a main gate (G3). Depending on the applied gate voltage (Vg), the module will either be in a forward-blocked, reverse-blocking, or conducting state. When a gate voltage of lower than the threshold voltage (VT) is applied, the module will be in a forward-blocked or reverse-blocked state, and no current will flow in the device. When a gate voltage higher than the threshold voltage is applied, the module will enter a conducting state, and current will enter the device.

The conduction angle of the VS-VSKK230-12PBF can be adjusted in two ways. First, the main gate voltage can be reduced to a lower value, and second, the gate voltage can be turned off when the conduction angle has reached the desired value. In addition, the device has over-current, reverse-current, and thermal protection functions, which can ensure the safe and reliable operation of the device in the application.

In summary, the VS-VSKK230-12PBF is a three-phase silicon controlled rectifier (SCR) module, and it is mainly used in power control applications such as industrial computer control, medical electrical equipment, telephone, military equipment, and other industries. The device is composed of three SCRs, and it can provide over-current, reverse-current, and thermal protection functions, which can ensure the reliable operation of the device in the application.
