Description

The 300W 20A DC-DC Buck Converter Step Down Module Constant Current LED Driver Module can be used to get adjustable output voltage ranges from 12V to 36V. The module provides a wide range of current output up to 4A. With the heat sink mounted, it can easily manage to run high-power applications continuously (provided that for continuous high-power output, you need to use a cooling fan on the heat sink).
The 300W 20A DC-DC Buck Converter module is made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current (when 20°C to 100°C constant current 15A, temperature drift less than 1%), and therefore it is particularly most suitable for LED driver applications. The output current of the module can be raised up to 20 A (for continuous use it is recommended up to 3A with an additional cooling fan).
Applications:
1. High-power LED driver.
2. Lithium battery(or lead accumulator) charge.
3. Vehicle-mounted power supply.
4. Low voltage system power supply.
5. 6V, 12V, 14V, 24V battery charge.
6. On-board laptop power supply.
7. regulated power supply.
8.Low voltage power supply system.
Note: If the module temperature exceeds 65ºC, please add a cooling fan,  (It be used at room temperature without a fan)

How to do the Module adjustment:

When the module output voltage cannot be adjusted (the output voltage is always equal to the input voltage) Please adjust the potentiometer counterclockwise 20 laps (20 turns) or more till it works.?
Turn trimmers CLOCKWISE to INCREASE, ANTICLOCKWISE to DECREASE.
When adjusting the blue potentiometer, please use a multimeter to monitor the voltage
The trimmer nearest the voltage output adjusts the output CURRENT (CC)
The trimmer nearest the voltage input adjusts the output VOLTAGE (CV)
