300W 20A BUCK CONVERTER

• 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.

• It is convenient with these large current 30A screw terminals.

• The dual module has 2 heat sink that can enhance heat dissipation.

• When there is a big difference between input and output voltage, please

  decrease power and current.

• Input voltage: 8V to 40V DC (10V to 36V is suggested)

• Output voltage: 1.2V to 36V DC.

• Output current: 20A (max.), 15A (suggested).

• Efficiency: 95% (24V to 12V, 20A) Add fan if the module exceeds 65°C.

• Output ripple: <50mV.

• Wiring method: Terminal.

• Short circuit protection: Self-recovery (cannot short circuit for long

  time).

• Size: 60 x 53 x 27mm.

• 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 to shut off, output compensation, high voltage

  level to effective.

• Then input and output is common ground, no-load CV output constant

  voltage, CC output constant current.

• Adjust CV potentiometer, according to your load requirements, the output

  voltage to the voltage value you need.

• Counterclockwise set CC potentiometer about 30 laps (that is, the output

  current set to the minimum), connected to the LED, adjust CC potentiometer to

  the current you need. For battery charging, put the battery after the power

  on, and then connect to the output, adjust CC to the current you need (if the

  charging must be used to put the power of the battery to adjust, because the

  battery left, the more power, charging current is smaller).
