When 220 inputs, the voltage is rectified by D1/C1 to obtain about 220 x 1.414V 310V, and the voltage is divided by R1/R7/D3.R11, so that when 170 and 264Vac inputs, the V1 triode is triggered to turn on V2, and the relay is in an off state, therefore, the N line cannot be connected with C1/C2, and the standard bridge rectification is adopted, namely, the sum of the voltages of the series capacitor C1/C2 is 310V

R2/R8/Z1/C2/R9/R10/Q1 belongs to a double-insurance voltage division network, and the principle is the same.
