Load Regulation rate: ±1% (constant voltage)

Voltage Regulation rate: ±1%

Constant Current Accuracy and Temperature: In actual test, the temperature on the module changes from 25 degrees to 60 degrees, and the constant current value changes less than 5% (constant current value 5A)

Dynamic Response Speed: 5% 200uS

Potentiometer Adjustment Direction: clockwise (increase), counterclockwise (decrease) close to the input potentiometer for voltage regulation (CV), near the output potentiometer for current regulation (CC)

Indicator Light: Two-color indicator light, the indicator light is red during charging, the charging completion indicator is green (no load is green) The indicator without constant current is red.

Output Short Circuit Protection: Yes, constant current (current setting constant current value)

Input Reverse Connection protection: none

Output Prevents Backflow: none

Wiring Method: terminal block

Application: adjustable power supply (12A power is large enough), high power LED driver, LED display driver, lead battery charging, lithium battery charging, vehicle power supply, car laptop power supply (buck), regulated power supply, low voltage system power supply

Feature:

Double heat sink design, MOS tube Schottky diode independent heat sink, good heat dissipation

The large-size iron-silicon-aluminum magnetic ring, and the double copper wire is wound together to reduce heat generation and improve efficiency.

Fine workmanship and good performance.

Easy to use.

Long service life.

Battery Charging Usage:

1. Determine the float voltage and charge current of the rechargeable battery you need, the input voltage of the module;

2. Adjust the constant voltage positioner and adjust the output voltage to about 5V.

3. Use the multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined charging current value;

4. Adjusting the constant voltage position device to make the output voltage reach the float voltage;

5. Connect the battery and try to charge.

(1, 2, 3, 4 steps are the module input connected power supply, output no-load, not connect battery.)

LED Constant Current Drive Usage:

1. Determine the operating current and maximum operating voltage at which you need to drive the LEDs;

2. Adjust the constant voltage positioner and adjust the output voltage to about 5V.

3. Use the multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined LED operating current;

4. Adjust the constant voltage positioner to make the output voltage reach the maximum working voltage of the LED;

5. Connect the LED and test the machine.

(1, 2, 3, 4 steps are the module input connected power supply, output no-load, not connect the LED light.)
