Feature

●Can not be used directly with 12V battery or DC as a power supply
●Chip has high conversion rate and strong driving ability
●Effectively eliminates high frequency interference in AC power grids
●The power circuit uses a full bridge rectifier
●Better performance, noise is very small


Description

Description n :

High quality filter power Each connects to 4 pin decoupling capacitors in parallel rectifiers. This allows for high frequency interference of AC power grids. 2 x 2200UF25V Electrolyte Capacitors filter negative power and then stabilize voltage 7815 and 7915 double DC power supplies. The clutter interference cable is very small and the voltage is very stable. Thats why we have a better performance than the item. The chip has high conversion rate and strong driving ability. Wide frequency band and very low noise
