DC-DC Buck Converter 300W 20A Step Dowm Module Adjustable Voltage 6 40V To 1.2 36V Power Supply Volt Reducer

OverviewFeatures: This Constant Current Power Supply Volt Reducer Module with a wide range of input from 6V to 40V,the step-down converter can accurately adjust output voltage and current. The efficiency max can be up to 95%,measured at 20A,converting 24V to 12V. The buck converter designed with dual MOS tube of large current 75V / 80A. Adopt with high frequency low resistance electrolytic capacitor for input and output use,low ripple, stable output. Board mounted 2 heat sink,enhance dissipation function for the step dowm module. Wiring is convenient with these large current 30A screw terminals.  When there is a big difference between input and output voltage,please decrease power and current.
