Specification: Item Type: Buck Boost Converter Material: Plastic Product Model: 5KX Input Voltage: 6-36 (V) Output Voltage: 0.6-36 (V) Output Current: 5A Output Power: 80 (W) How to Use: 1. Switch the Display Parameters: In the normal interface, short press the SW key to switch the lower display of the display. The display content is switched between current A, power W, capacity Ah, and time H. Long press the SW button to switch the upper display of the screen, and the display content is switched between input voltage IN and output voltage OUT temperature ℃. 2. Set the Output Voltage Value: Short press the U/I button in the normal interface to enter the set voltage constant current interface. You can see that a certain digit of the output voltage value is flickering. Turn the rotary encoder left and right to adjust it to increase or decrease. Short press the rotary encoder to set which bit of the output voltage to rotate. After the setting is completed, short press the U/I button twice to return to the normal interface. Or after stopping the operation for 10S, it will automatically return to the normal interface Package List: 1 x Buck Boost Converter Package List 1 x Buck Boost Converter
