The 200W 20A DC-DC Buck Converter Step Down Module Constant Current LED Driver Module can be used to get adjustable output voltage ranges from 1.2V 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 200W 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), also color may be different.
How to do the Module adjustment:
  1. 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.?
  2. Turn trimmers CLOCKWISE to INCREASE, ANTICLOCKWISE to DECREASE.
  3. When adjusting the blue potentiometer, please use a multimeter to monitor the voltage
  4. The trimmer nearest the voltage output adjusts the output CURRENT (CC)
  5. The trimmer nearest the voltage input adjusts the output VOLTAGE (CV)

Features:

  1. Scope: High-power LED constant current driver, rechargeable lithium batteries 4V, 6V, 12V, 14V, 24V
  2.  Constant Output current value of 15A.
  3. Output Ripple: about the ripple 50mV (without noise)
  4. Operating temperature: -10 ℃ to + 75 ℃

Package Includes:

1 x 200W 20A DC-DC Buck Converter Step Down Module Constant Current LED Driver Module

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
