USB Color Screen Charging Tester Boost Voltage Power Supply PD Detection Type-C Voltmeter XY-UMPD

Ammeters2. The product has constant current function, which can charge all kinds of small rechargeable batteries within 0.6V~30V within 10~20W;Charging steps:(1) Determine the floating charge voltage and charging current of your rechargeable battery; (if the parameter of lithium battery is 3.7V/2200mAh, the floating charge voltage is 4.2V; if it is 12V rechargeable battery, generally set the floating charge voltage to about 14V)(2) Under no-load condition, set the output voltage to floating charge voltage; (if 3.7V lithium battery is charged, adjust the output voltage to 4.2V)(3) Set the charging current (constant current value) and set the current directly. Note: when setting the current, calculate the lower power, charge within the power range, and use the super power, the product will enter the protection state.(4) Connect the battery for charging.3. The product has constant current function, which can directly drive 0.6-30V,0-15W LED lamp;To drive the LED lamp:(1) Determine the working current and maximum working voltage you need to drive the LED;(2) Under no-load condition, set the voltage value and current value to make the output voltage the maximum working voltage and current of LED (Note: calculate the power when setting thecurrent, charge within the power range, use over power, the product will enter the protection state.)(3) Connect the LED and test the machine.This product can adjust the constant current value (between 0 - working current) to realize the LED's stepless dimming and no stroboscopic!!
