Minimum Voltage Difference:2V

Full Load Temperature Rise: 45 deg C


Specification:

Working Temprature:Industrial grade (from -40 ℃ to +85 ℃)(when ambient temprature is over 40 deg C, please step down power or add one heatsink)

Size (L x W x H): Approx. 1.95 x1.6 x 0.51 inch / 5 x 4 x 1.3cm

Indicator Light

Constant current indicator (red LED)

Charging indicator(light red)

Charged full (Light Blue)

Applications:

High-power LED constant current driver

Lithium battery charger (including ferroelectric),4V, 6V, 12V, 14V, 24V battery charger,Nickel , nickel metal hydride battery pack charger

Solar panels and wind driven generator.

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

The charge current of transfer lamp is default 0.1 times of the charging current (constant current value)

Connected to the battery and try to charging (for previous 5 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 being up to About 3V

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 LED operating current

Charging turn the light of current default value is 0.1 times of the charging current.(if you need current adjustment, please turn potentiometer adjustment)

Adjust constant voltage potentiometer to make the output voltage reach float charge voltage

Final Step, Connected to the battery, try charging,have sufficent




Package Includes:

1 x Adjustable DC-DC Step Down Power Supply Module
