[Product Features]
1. Onboard voltage, current, and power meters, you can easily use this module without a multimeter, which is simpler and more intuitive.
2. The onboard USB interface allows for easy charging of your digital products. (Note: The USB output voltage is consistent with the module output voltage and is 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) Used as a common voltage reduction module with overcurrent protection capability;
(2) As a charger for lithium batteries, batteries, nickel cadmium nickel hydrogen batteries (battery packs) with various voltage values, it is used in applications such as solar panels and wind turbines;
(3) Used as a high-power LED constant current driver module;
5. It has two modes: constant voltage and constant current, with indicator lights indicating which mode the module is currently in;
When used as a lithium battery charger, the float charging voltage and charging current can be set, and there is an indicator light to indicate whether it is charging or fully charged;
7. It has a current limiting protection function, which will not burn out the module even if the output is short circuited.

【 Usage 】
▼ Used as a common voltage reduction module with overcurrent protection capability
(1) Press the button on the right to adjust the digital meter to the 'Display Output Voltage' interface,
Adjust the 'constant voltage potentiometer' to achieve the desired output voltage value;
(2) Adjust the digital meter to the 'Display Output Current' interface and short-circuit the module directly
At the output end (short circuit the output end with a thick wire), adjust the "constant current" at this time
Potentiometer "enables the current value on the digital meter to reach the preset overcurrent protection value; (For example)
The current value displayed on the onboard ammeter is 4A, so the maximum current of the module is limited to
4A， When the current reaches 4A, the red indicator light will turn on
(3) Connect the load and work.
▼ Used as a battery charger
Modules without constant current function cannot be used to charge batteries because they are depleted
The voltage difference between the battery and the charger
No-delivery refund
