Why Does A Static Voltage Stabilizer Exit The Voltage Regulation State?

When the input voltage fluctuations exceed the device's set regulation range, the internal control module of the static voltage stabilizer manufacturers will be unable to maintain a stable state, causing the device to stop regulating the voltage and switch to bypass or non-regulation mode.

Static voltage stabilizers use fast electronic switching elements such as SCRs or IGBTs for voltage regulation. These components rely on precise trigger control to dynamically adjust the input waveform. When the input signal amplitude exceeds predetermined upper and lower limits, the control logic cannot generate an effective trigger strategy, and the voltage regulation module automatically exits the regulation cycle, thus ceasing its correction of the output voltage.
