Using 8A bridge rectifier, the device back extroverted. when output high current needs to add heat sink, two large filter electrolytic capacitors, two-stage filtering, the main capacitor is 4700uF/35V, or 3300uF /50V, and then pair the corresponding 470uF/35V and 470uF/50V small electrolytic capacitor, suitable for 50V power supply appliances, equipment, audio, etc., to provide low internal resistance, low ripple power supply. The electrolytic capacitor of the power supply is a domestic genuine capacitor, there are several brands, before shooting can consult the brand of the electrolytic capacitor used. Before using the board, make sure that the output voltage of the power transformer you are using, as well as the range of power supply fluctuations, reserves a certain amount of voltage margin.
maximum input AC voltage: AC20V 3300uF/50V,
maximum input AC voltage: AC30V
Output current maximum 8A (heat sink required)
