12V-PSU.FOR.HUB2

The AJAX 12V-PSU for Hub 2 (also called 12V PSU for Hub 2/ReX 2) is an internal power supply board that replaces the standard 110/230V AC unit, enabling Hub 2 control panels (and ReX 2 extenders) to run on low-voltage DC sources like 12V batteries, car power, or unstable grids.
It's designed for off-grid, mobile, or backup scenarios, delivering stable power with protection against undervoltage, and installs directly into the device's enclosure for seamless integration.
