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

Description:

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.

Note:

Output current regulation method:
1 - Adjust CV potentiometer, according to your load requirements, the output voltage set to the voltage value you need.

2 - 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, and then connect to the output, adjust CC to the current you need, (for charging must be used to put the power of the battery to adjust, because the battery left in the more power, charging current is smaller.)

Features:

  • 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)Add fan if the module exceeds 65 degrees!
  • Output Ripple: <50mV
  • Wiring Method: Terminal
  • Short Circuit Protection: Self-recovery(cannot short circuit for long time) TZT
  • Size: 60 x 45 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 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
