300W 20A DC to DC Voltage Step-down Converter


Only 2 left in stock

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, and gives a 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.



  • 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)
  • When input and output is common grounded, no-load CV output constant voltage,CC output constant current
