5A constant voltage constant current step-down power module with display LED drive lithium battery charging
With voltage, current, and power display, it can be used easily without a multimeter, and it is powerful!
With USB interface, with 3 major functions, it can satisfy most of your occasions!
Module highlights
1. Onboard voltage, current, power meter, you can easily use this module without a multimeter, which is more convenient and intuitive.
2. The onboard USB interface can easily charge your digital products. (Note: The USB output voltage is the same as the module output voltage, not a fixed 5V output, please confirm before charging the USB device)
3. High power, high efficiency, 5A, low ripple;
4. Three major functions:
(1) Use as an ordinary step-down module with over-current protection capability;
(2) Used as a charger for various voltage values of lithium batteries, batteries, nickel-cadmium nickel-metal hydride batteries (battery packs), used in solar panels, wind generators and other occasions;
(3) Use as a high-power LED constant current drive module;
5. With two modes of constant voltage and constant current, there are indicators to indicate which mode the module is currently in;
6. When used as a lithium battery charger, the float voltage and charging current can be set, and an indicator light indicates
Indicates whether it is charging or fully charged;
7. With current-limiting protection function, the module will not be burnt out even if the output is short-circuited.
8. The onboard voltage and ammeter can be self-calibrated, and there will never be inaccurate problems!
9. With heat sink, free copper pillar!

Scope of application
1. Use as an ordinary step-down module with over-current protection capability
Instructions:
(1) Press the button on the right to adjust the digital meter to the [Display output voltage] interface, and adjust the "constant voltage potentiometer" to make the output voltage reach the voltage value you want;
(2) Adjust the digital meter to the [Display output current] interface, and directly short-circuit the output terminal of the module (just find a thick wire to short-circuit the output term
