    Product Overview
    DC 300W 20A Step-Down Adjustable Voltage Buck Converter CC CV Constant Current
    300W 20A Step down
    Features:
    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.
    Specifications:
    Input Voltage: 6V to 40V DC(10V to 40V is suggested)
    Output Voltage: 1.2V to 36V DC
    Output Current: 20A(max.), 15A(suggested)
    Efficiency: 95%(24V to 12V, 20A)
    Output Ripple: ≤50mV
    Wiring Method: Terminal
    Short Circuit Protection: Self-recovery(cannot short circuit for long time)
    Size: 60 x 53 x 27mm / 2.36 x 2.08 x 1.06"
    VO+: Output positive
    VO-: Output negative
    +IN: Input positive
    -IN: Input negative
    CV: Output voltage adjustment
    CC: Output current adjustment
    EN: Enable, low voltage level shut off output; suspension, high voltage level is effective
    When input and output is common grounded, no-load CV output constant voltage,CC output constant current
    Package Include:
    1 x 300W 20A Constant Current Adjustable Buck Converter Step-Down Voltage Module
    1W 350mA Step down
