Fangrui Product Details High-frequency And High-voltage Ac Output Can Be Used To Power The Voltage Doubler Rectifier Board, And Can Also Be Used To Charge The Capacitor After Rectification. It Must Be Powered Within The Nominal Voltage Range To Work Properly! If The Voltage Is Too Low, The Module Will Stop Working Due To Undervoltage. Reverse Connection And Overvoltage Are Strictly Prohibited, Otherwise The Module Will Be Damaged And Even Cause The Capacitor To Explode! Note: This Product Is A Semi-finished Product Without A Shell, And The Photo Is The Actual Product.
