When your system needs a stable 12V rail from a variable DC supply, this industrial-grade buck-boost converter is built to deliver. It accepts a wide 8 to 36VDC input range and regulates it to 12V for loads up to 6A, or 72W.
The buck-boost design automatically switches between stepping voltage down and stepping voltage up to maintain a constant output. This makes it especially useful for 12V battery applications, such as SLA or LiFePO4 packs, where the voltage can vary significantly between charging and discharge.
The unit is a fully enclosed DC block designed for set-and-forget reliability, with extensive internal heat sinking and protection circuitry for rugged environments. A datasheet for the WG8-36S1206 is provided by the manufacturer.
Features:
- Buck-boost regulation: Seamlessly switches between stepping voltage down and stepping voltage up to maintain a constant output.
- Battery applications: Suited to 12V battery applications like SLA or LiFePO4.
- Rugged design: Fully enclosed DC block for set-and-forget reliability.
- Thermal management: Extensive internal heat sinking.
- Protection circuitry: Includes protection circuitry for harsh environments.
- Manufacturer's warranty: 2-Year Manufacturer's Warranty
Specifications:
- Input Voltage: 8 to 36VDC
- Input Current: 11A DC Max
- Quiescent Current: 25mA
- Efficiency: 85%
- Output Voltage: 12V
- Output Current: up to 6A
- Output Power: 72W
- Output Voltage Accuracy: ±1%

A practical choice for battery-powered 12V equipment, vehicle-adjacent projects, and other installations where the input voltage may sit above or below the required output.
Jargon buster
Plain-language definitions for the technical terms used above.
- boost converter
- A boost converter is a power circuit that raises a lower input voltage to a higher output voltage. It matters here because the board can power a sensor that needs a higher supply voltage while still using a single connector for power and data.
