Synchronous DC-DC buck-boost power supply module constant voltage constant current battery charging
Product Description :
The constant voltage constant current type automatic step-up and step-down module has been praised and praised by many users since it was put on the shelves! Wide range of use, excellent stability! Now upgraded version, with higher conversion efficiency, lower heat, optional shell and so on!
This product does not contain a metal case, please purchase separately.
First, constant current and anti-reverse irrigation function, suitable for battery charging!
Constant voltage constant current type module with current potentiometer, can adjust the output current upper limit! The output voltage does not sink to the input, so it is especially suitable for battery charging!Second, the ability to boost can also be reduced!
Example 1: The input voltage can be stable at 12 volts regardless of whether the input voltage is higher than 12 volts or lower than 12 volts!
Example 2: Power the module 12 volts, the output can be stepped down to 5 volts, and can be boosted to 24 volts!
Third, you can set the constant current value without a multimeter!
Fourth, perfect protection function!
MOS type anti-anti-burn circuit, input undervoltage shutdown, input/output overcurrent protection, etc.
Five, full of turn-light function! Easy to use!
When the constant current is charged, the red and blue lights are on. When the constant voltage is charged, only the blue light is on. When it is nearly full, it lights up in blue and green. When it is full, it only lights up in green!

As different computer display the colors differently,and the color maybe is little difference from the actual items,but we can guarantee the style is same,but maybe some not same performance on different bodies as on the models.Hope you can understand it.thank you！
