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

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 charge 3. 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 stroboscopic!!

Note: The maximum output power is 15W.When the input current is greater than 3A, long-term operation may lead to over-temperature protection,even if it does not reach 15W. When the input voltage is higher than 8V, the full power can beused. When the input voltage is lower than 5V, the lower the input voltage is the lower the output power is. The ​general 5V charging adapter itself is difficult to output 15W power, so don't expect the full power operation of the product with the ​general charging head. If the charging head supports the fast charging function, it is recommended to activate the fast charging and output high voltage, so that the full power operation can be possible. This product supports QC2.0/QC3.0, for Huawei FCP/SCP for Samsung AFC. This product has soft startno impact on load when starting.
