Crystal case, beautiful design, good touch and touch texture;
The button can control the output to be turned off, and the power-on default can be set to ON or OFF;
The liquid crystal can display input and output voltage and output current output power;
The input end is anti-reverse protection, and the reverse connection will not burn;
High efficiency of more than 95%, high current, low heat, output voltage 1.2 - 32V can be adjusted freely, constant current value 0-12A can be adjusted, suitable for high-power LED constant current drive, lithium battery charging, etc.!
Product parameters:
Input voltage: 5.3 - 32V ( minimum input can be input to 4V to achieve step-down, but the voltage and current measurement is not accurate when the input is lower than 5.3V ) 
Output voltage: 1.2 - 32V  ( The input voltage must be higher than the output voltage, the minimum differential voltage is 0.8V ) 
Output current: can work stably at 8A for a long time, and can reach 12A under enhanced heat dissipation
Output power: natural heat dissipation 120W ( within 8A ), enhanced heat dissipation 160W
Voltage display: resolution 0.05V, range 0 - 32V
Current display: resolution 0.01A, range 0 - 12A
Conversion efficiency: about 96%
Working current: about 25mA
Material: fiber component
Soft start: Yes ( large power with load module may fail when starting )
Input reverse connection protection: Yes
Output anti-backflow: no ( if charging the battery, first power on the module and then connect the battery, and ensure that the battery voltage is lower than the output voltage; if there are conditions, please connect the anti-backflow diode in the output positive pole )
Short circuit protection: Yes
Module factory default output voltage and current is about 18V/7A, because this module is a buck module, you need to lower the output voltage below the input voltage to work, if you receive the module and found that the output voltage cannot be adjusted Please turn the CV voltage adjustment potentiometer counterclockwise for more than 20 turns, then use the module to adjust the voltage normally; the module is DCDC DC to DC step-down module, can not input the transformer directly to step down the AC; if it is to the battery / battery Charging, you need to prevent a reverse sink diode in the positive terminal of the output terminal, otherwise the battery's electric backflow will easily damage the module; if the current and power are too large, please strengthen the heat dissipation or pay attention to the heat sink temperature to prevent burning.
