300W 20A DC-DC Step-down Adjustable Constant Current 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 20 A. 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 Module is made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20C to 100C constant current 1A, 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 20A(for continuous use it is recommended up to 15A with an additional cooling fan).
To enhance the stabilization in output voltage has six high-frequency capacitance which gives the lower output ripple. Double heat sink design provides easy and fast heat dissipation. MOS Schottky diode independent heat sink, which heat dissipation is good, and wont affect each other. Also using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever.
The module has onboard 3296 multiturn potentiometers for high accuracy voltage and current regulation to provide good stability. As voltage and current are adjustable, it gives very easy to use at multiple Application such as battery charging, LED Driver power supply, Vehicle Power Supply, etc which makes the module Multipurpose and hence this module is always in demand from our maker because of its wide range of application and low cost.
