300w 20A CC CV Adjustable Buck Converter DC-DC Constant Current Constant Voltage Adjustable Step-Down Voltage Module 20A 300W for Solar Charge Controller LED Driver with ON/OFF Switch

With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current.The efficiency can be up to 96%, measured at 20A, converting 24V to 12V.It is designed with 75V/80A large current dual MOS tube.Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output.Wiring is convenient with these large current 30A screw terminals.The buck module has 2 heat sink that could enhance heat dissipation.When there is a big difference between input and output voltage, please decrease power and current.
