Step Down Buck Converter Charger 15W LM2596 3A **LOCAL STOCK**

Step Down Voltage + Current 15W 3A:

Specifications:

Input Voltage: 5-35V
Output Voltage: Continuously adjustable from 1.25 V to 30V
Rated Output Current: 3A Max
Size: 48 x 24 x 13mm
Indicator Light:
Constant current indicator (red)
Charging indicator (red)
Charged full (green)

Battery Use:

Make sure of the voltage and current of the battery you need to charge
Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage
Potentiometer Adjustment Direction: Clockwise (increase), counterclockwise (decrease)
Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make sure the output current to the expected charging current value
Connect to the battery and try to charging (for previous 4 steps, module input terminal is connected to power source, output load is NOT connected to batteries)
 
LED Constant Current Driver Use:

Make sure operating current and Max operating Voltage of the LED you need to drive
Adjust the constant voltage potentiometer to make sure the output Voltage is up to LED Max operating Voltage
Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer
Set the output current to the expected LED operating current
Join LED, test (For the above 3 steps, module input terminal is connected to power source, output load is NOT connected to LED)

* If the Output current is greater than 2.5A (or output power greater than 10W) to work long hours, please add 14x14x5mm heat sink to IC Chip
