DC-DC 20A Step-down Constant Voltage Constant Current Adjustable Car Power Supply Module High Power LED Driver 300W

Features:
This constant current step-down power supply module with a wide input range from 6V to 40V, the step-down converter can precisely adjust the output voltage and current.
The maximum efficiency can reach 95%, measured at 20A, converting 24V to 12V.
The step-down converter designed with dual MOS tube of large current 75V / 80A.
Adopt with high resistance and low resistance electrolytic capacitor for input and output use, low ripple, stable output.
2 heat sinks mounted on the board, improve the dissipation function for the step dowm module.
Wiring is convenient with these screw terminals of large current 30A.
If there is a large difference between the input and output voltage, please reduce the power and current.
