Feature:
1. Step down module uses high-quality materials, which can be durable and practical to use.
2. The electrolytic capacitor has high frequency, low resistance, and stable output.
3. When both input and output are grounded, the constant voltage output CV has no load and the constant current DC output.
4. Electronic component's wiring method is by terminal. car power board installation is simple, which not requires particularly complicated operations.
5. Car power board can be suitable for high-power LED constant current drive, lithium battery charging including ferroelectric, 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-hydrogen battery (battery pack) charging, solar panels and wind generator.
