USB power system (PER) application:
1. Used as a regular voltage rise/fall power supply with overvoltage/overcurrent/overpower/over temperature/under voltage protection;
2. This product has a constant current function, which can charge various small rechargeable batteries within 0.6V-30V within 10-20W;
Charging steps:
(1) Determine the float voltage and charging current of your rechargeable battery; (If the lithium battery parameter is 3.7V/2200mAh, then the float charging voltage is 4.2V. If it is a 12V rechargeable battery, the float charging voltage is generally set to around 14V.)
(2) Under no-load conditions, set the output voltage to reach the float charging voltage; (If charging a 3.7V lithium battery, adjust the output voltage to 4.2V.)
(3) Set the charging current (constant current value) and simply set the current. Note: When setting the current, it is necessary to calculate the power and charge within the power range. If used beyond the power range, the product will enter a protective state.
(4) Connect the battery to charge.
3. This product has a constant current function and can directly drive 0.6-30V, 0-15W LED lights;
Steps for driving LED lights:
(1) Determine the working current and maximum working voltage that you need to drive the LED;
(2) Under no-load conditions, set the voltage and current values to reach the maximum operating voltage and current of the LED output voltage (note: when setting the current, calculate the power and charge within the power range. When using at excessive power, the product will enter a protective state)
(3) Connect the LED and test the machine.
This product can achieve infinite dimming and flicker free LED by adjusting the constant current value (between 0 and working current)!!
