The utility model relates to a fixed point voltage regulator, which is mainly suitable for measuring micro light meters. General regulators require input voltage stability in the range of 10 to 15%, the scope of fluctuation is greater, then regulators can not guarantee the accuracy of voltage regulation, can not meet the use requirements. The utility model relates to a new fixed-point voltage stabilizer, which is composed of a thyristor AC voltage regulator circuit in parallel, step-down transformer, rectifier filter and shunt resistance expansion flow three terminal integrated voltage regulator. The regulator when the input voltage fluctuation above 30% (145 ~ 290 V) can still maintain output voltage regulator, voltage accuracy is less than 0.4%.
