Description:
filter power supply. The four pins of rectifier respectively in parallel connect with decoupling capacitor, which can effectively eliminate the interference of AC power grid. Two 2200UF25V electrolytic capacitor filter the negative power supply, then stabilize voltage with 7815 and 7915 double DC power supply. Now the clutter interference of power grid is very small and the voltage is quite stable. So the item has better performance.The chip has high conversion rate and strong drive ability. The frequency band is wide and noise is very small.
