300W 20A DC-DC Adjustable Step Down Buck Converter

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"

 Wiring Diagram: 

• 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
