Working Principle

The working principle of 60BK565-S090N1 consists of three parts. Firstly, the device detects the voltage level and compares to the set level; secondly, if the voltage exceeds the set level, the thyristors are turned ON simultaneously; finally, the overvoltage is interrupted through the divergence of inrush current, which limits the voltage to the set level.

The process can be divided further into three steps. In the first step, the instantaneous phase-to-phase voltage is detected by a voltage detector circuit, which is then compared to fixed preset trip level value. In the second step, the thyristors are turned ON by a control circuit if the detected voltage is higher than the preset threshold. In the final step, the thyristors cut-off the current flow through the over-voltage load and discharge the over-voltage. This also generates and discharges the reverse recovery current so as to ensure protection.

In short, the working principle of 60BK565-S090N1 is to detect the magnitude of voltage, then turn on thyristors to limit the voltage and discharge the circuit over-voltage.

Conclusion

To sum up, 60BK565-S090N1 is a type of three-phase thyristor protection voltage limiters which are applied in industrial and high tech areas. Its operation is based on a three-step process that detects the voltage levels, turns on thyristors and discharges the over-voltage. This device is very useful and efficient when it comes to protecting electronic equipment and systems from sudden over-voltage.
