Tips: Why is the voltage of a 50kVA industrial voltage stabilizer unstable?

1. The input voltage is too high or too low. The voltage range of 50kVA three-phase instrial voltage stabilizer is 304V-456V. If the input voltage exceeds the regulated range or is very low, the automatic protection system of the regulated power supply will start, thus causing the output voltage to be unstable or stop working directly.
2. The input voltage is unbalanced in three phases, that is, the voltage of one of the three phases of the stabilizer is unstable, which will also lead to the output voltage of the stabilizer is unstable.
