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).
