## Description

This is an industrial grade DC Buck-Boost converter that inputs 8V to 40V and outputs 12V up to 3A or 36W. With tons of heatsinking and protection, this DC block is perfect for battery applications (such as SLAs or LFPs) that need to power a steady load (such as 12V router and WiFi equipment) even while the input is varying (battery charge/discharge). 85% efficiency makes this a good, plug and play, DC Step-Up/Down solution.
