Specification:
Description:
High quality filter power supply. The four pins of rectifier respectively in parallel
connect with decoupling capacitor, which can effectively eliminate the
high frequency interference of AC power grid. 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.
