An industrial-grade DC buck-boost converter that accepts 8–40V input and delivers a regulated 12V output at up to 3A (36W). Ideal for battery-powered systems where input voltage varies — such as SLA or LiFePO4 batteries powering routers, Wi-Fi equipment, or other 12V loads — this module automatically steps voltage up or down to maintain a steady 12V output.

With 85% efficiency, generous heatsinking, and built-in protection, this is a reliable plug-and-play DC-DC solution for a wide range of power conditioning applications.

Key Features

  • Buck-Boost Operation – Steps voltage up or down to deliver steady 12V output
  • Wide Input Range – 8–40V DC input for flexible power sourcing
  • 12V / 3A Output – Up to 36W regulated output
  • 85% Efficiency – Minimises heat and power waste
  • ±1% Output Accuracy – Tight voltage regulation
