1. On-board voltage, current and power meters, you can easily use this module without a multimeter, which is more simple and intuitive.
2. On-board USB interface can easily charge your digital products. (Note: The output voltage of USB is the same as the output voltage of the module. It is not a fixed 5V output. Please confirm before charging the USB device.)
3. High power, high efficiency, 5A, low ripple;
4. Three main functions:
(1) It is used as a common step-down module with over-current protection capability.
(2) Used as chargers for lithium batteries, batteries, nickel cadmium nickel hydrogen batteries (batteries) with various voltage values, for solar panels, wind turbines and other occasions;
(3) It is used as a constant current drive module of high-power LED.
5. There are two modes: constant voltage and constant current, and which mode is the indicator module currently in?
6. When used as a lithium battery charger, floating charging voltage and charging current can be set, with an indicator light pointing.
Is it charging or full?
7. It has the function of current limiting protection, even if the output is short-circuit, it will not burn the module.
8. On-board voltage and ammeter can be self-calibrated, and there will never be inaccuracy!
9. With radiators, give copper pillars!
