Applications:

Power System (PER):

1. Use as an ordinary buck-boost power supply with over-voltage/over-current/over-power/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 15W;

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 voltage is 4.2V, if it is a 12V rechargeable battery, generally set the float voltage to Around 14V)

(2) Under no-load conditions, set the output voltage to reach the float voltage; (if charging a 3.7V lithium battery, adjust the output voltage to 4.2V)

(3) Set the charging current (constant current value), just set the current directly. Note: When setting the current, calculate the power, charge within the power range, use over power, the product will enter the protection state.

(4) Connect the battery to charge.

3. This product has a constant current function, which can directly drive 0.6-30V, 0-15W LED lights;

Steps to drive LED lights:

(1) Determine the operating current and maximum operating voltage you need to drive the LED;

(2) Under no-load conditions, set the voltage value and current value so that the output voltage reaches the maximum LED working voltage and working current (Note: When setting the current, calculate the power, charge within the power range, use over power, the product will enter Protection status.)

(3) Connect the LED and test the machine.

This product can adjust the constant current value (between 0 and working current) to realize the stepless dimming of the LED without stroboscopic! !
