✍ High current 5A constant voltage constant current step-down power module LED drive lithium battery charging

When you use this product, please do not share the input ground and output ground of the module together. This will cause the current sampling resistor on the back of the board to be bypassed, so that the module cannot adjust the output current. It is easy to connect to the load. Burn the power chip on the module .

✍ 恒流功能来说是控制与限制输出电流的能力，一来防止输出过大的电流烧毁负载，二来可以防止瞬间的大电流烧毁模块。 一般的不带恒流的模块，在短路的瞬间极有可能直接把模块烧了，而恒流的情况下，电压会被强制拉低，不至于马上烧毁。 当然，就算有恒流的帮助下，短路的时间也不能太长，毕竟芯片是在满载运行的，温度一旦升得太高也有可能带来不必要的损伤。

Example:
Step down only
✅ 32V > 24V / 12V / 9V / 5V / 3.3V
✅ 24V > 12V / 9V / 5V / 3.3V
✅ 12V > 9V / 5V / 3.3V
✅ 5V > 3.3V

Unable to step up
❌ 5V > 9V / 12V / 24V / 30V
❌ 12V > 24V / 30V

▼ Features:
1. High power, high efficiency, 5A , low ripple;

2. Three in one:
( 1 ) Use as an ordinary step-down module with overcurrent protection capability;
( 2 ) Used as a charger for various voltage values ​​of lithium batteries, batteries, nickel-cadmium nickel-metal hydride batteries (battery pack), used in solar panels, wind generators, and other occasions;
( 3 ) Use as a high-power LED constant current drive module;

3. It has two modes of constant voltage and constant current, and there are indicators to indicate which mode the module is currently in;

4. When used as a lithium battery charger, the float voltage and charging current can be set, with indicator lights indicating, shows whether it is charging or fully charged;

5. With the current limiting protection function, the module will not be burnt out even if the output is short-circuited.
