Description:
High-quality filter power supply. The four pins of the rectifier are connected in parallel with decoupling capacitors, which effectively eliminates high-frequency interference from the AC power grid. Two 2200UF25V electrolytic capacitors filter the negative power supply, and the voltage is stabilized with 7815 and 7915 dual DC power supply. The interference from the power grid is minimal and the voltage is stable, resulting in better performance. The chip has a high conversion rate and strong driving ability, with a wide frequency band and very low noise.

Feature:
1. The power supply circuit adopts full bridge rectifier.
2. Effectively eliminate high-frequency interference from the AC power grid.
3. Chip has a high conversion rate and strong driving ability.
4. Better performance, very little noise.
5. Cannot use 12V battery or DC directly as power supply.
