About this item
  • The DC-DC converter module has a wide input voltage range from 6V to 40V, the step-down converter can precisely set the output voltage and the current
  • The efficiency can be up to 96%, measured at 20A, to convert 24V to 12V.Bilateral 25mm height heat sink
  • The DC-DC converter module is equipped with a 75V / 80A large current double MOS tube
  • Input and output use high frequency low impedance electrolytic capacitor, low ripple, stable output power
  • Wiring is convenient with these large 30A screw terminals. The buck module has 2 heat sinks that could improve heat dissipation. If there is a big difference between input and output voltage, please reduce the power and current.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
