Product Description

DC-DC 12A Step-down Constant Voltage Constant Current Module Solar Lithium Battery Charging LED Drive Power Supply Module with Shell

Specifications:

Input voltage: 4-32V (limit 35V) Please keep the voltage margin.

Output voltage: 1.2-32V continuously adjustable (default output of about 18V, if the power to the module and found that the left and right rotary voltage potentiometer output voltage has not changed, you first turn the voltage potentiometer counterclockwise rotation of more than 15 laps )

Input and output minimum pressure difference: 0.8V

Output current: 0-12A long time natural heat within 8A, the temperature does not exceed 60 degrees. Please reduce power when the ambient temperature is high.

Conversion efficiency: up to 98% (efficiency and input, output voltage, current, pressure related)

Short circuit protection: Yes (limit current is current constant current value)

Input Reverse Protection: None (if required, enter the string in the input diode)

Output anti-backlash protection: none (if necessary, in the output string into the diode, for charging applications, please add the anti-diode between the output of the module and the battery, otherwise it will damage the module.)

Set the voltage and current method:

1, set the output voltage: according to the battery you want to charge the float voltage, or string, parallel to the LED voltage, adjust the constant voltage potentiometer (CV), the output voltage is set to the required voltage. (Without load )

2, set a constant current value: the first CC potentiometer counterclockwise 20 laps or so, with a multimeter 20A current file short-circuit output, adjust the CC potentiometer to you need to set the current value.

Application:

DIY a power supply, with constant current function, not afraid of the use of the process will be short-circuit, you can protect the load.

b, for your electronic equipment power supply.

c, for a variety of battery charging, according to different voltage and capacity of the battery set the charging voltage and charging current.

d, with solar panel power for a variety of battery charging, with constant current function, to prevent the battery overcharge, the effective protection of the battery.

e, drive high-power LED, free serial and parallel combination.

f, as a car power supply for your mobile phone, laptop or a variety of digital products.

Note: constant current set when the voltage is higher than 1.2V, otherwise the constant current function will be invalid.

Please use this product, the module input and output are not together, this will cause the module's current sampling resistor is bypassed, so that the module can not adjust the output current size, then the case of large load easily Burn the module.

A customer reflects the module output voltage can not be adjusted, when you encounter this problem, please counterclockwise rotation of the CV potentiometer more than 20 laps, and then use the module can be normal adjustment of the voltage. Because the module factory, The default output voltage of about 18V. 

Due to the light and screen difference, the item's color may be slightly different from the pictures.

Please allow 1-3cm differences due to manual measurement.
