XY-UDP Digital USB DC Converter CC CV 0.6-30V 5V 9V 12V 24V 2A 15W Power Module Desktop Adjustable Regulated Power Suppl

Application As a common boost and drop power supply with over voltage over current over power over temperature under voltage protection The product has constant current function and can charge all kinds of small rechargeable batteries within 0 6V 30V within 15W Charging step 1 Determine the floating charge voltage and current of your rechargeable battery If the lithium battery parameter is 3 7V 2200mAh the floating charge voltage is 4 2V if it is 12V rechargeable battery the floating charge voltage is generally set to about 14V 2 Under no load condition set the output voltage to reach floating charge voltage If charging 3 7V lithium battery adjust the output voltage to 4 2V only 3 Set charging current constant current value and set current directly Note When setting the current the power should be calculated charged within the power range and the product will enter a protective state if it is used with super power 4 Connect the battery to charge3 This product has constant current function can directly drive 0 6 30V 0 15W LED lamp Step of driving LED lamp 1 Determine the working current and maximum operating voltage of the LED you need to drive 2 Under no load condition set the voltage and current values to make the output voltage reach the maximum working voltage and working current of the LED 3 Connect the LED and test it This product can adjust the constant current value between 0 and working current to achieve LED polar dimming no stro
