Description

This industrial-grade DC Buck-Boost converter is a reliable solution for power systems that require a stable output from a fluctuating source. Whether you are running a solar setup, an automotive system, or a battery backup, this module accepts an 8V to 40V input range and delivers a clean, constant 12V output at up to 3A (36W).

Why a Buck-Boost?

Standard regulators stop working when the input voltage drops below the output voltage. This "Buck-Boost" unit is different: it automatically switches between stepping voltage down (Buck) and stepping voltage up (Boost).

  • Perfect for Batteries: This converter is essential for 12V battery applications (such as SLA or LiFePO4). A "12V" battery can swing from 14V when charging to 10V when depleted. This unit ensures your equipment remains powered throughout the charge/discharge cycle without interruption.

Rugged & Efficient

Designed for "set it and forget it" reliability, this fully enclosed DC block features extensive internal heat sinking and protection circuitry, making it suitable for harsh environments. With 85% efficiency, it minimizes power waste—a crucial factor when running off finite battery reserves.
