12V-PSU.FOR.HUB. HUB-PLUS-REX

The AJAX 12V-PSU for Hub 2/Hub 2 Plus/ReX 2 is an optional internal power supply module that adapts these devices to low-voltage DC sources (8-20V input), ideal for unstable grids, portable batteries, or off-grid setups.
It outputs a stable 4.8V ±3% at up to 1.5A to power the hub, installs by replacing the stock AC PSU board inside the enclosure, and supports average loads like 33-285mA depending on active modules (GSM/Ethernet/Wi-Fi).
