Ajax 6V PSU Hub 2/Hub 2 Plus/Rex 2

This power supply allows you to operate a Hub (4G), a Hub 2, a Hub 2 Plus, or a ReX 2 using a low-voltage power source. The board is mounted inside the device’s enclosure, in place of the 110–230 V power supply, without the need for an external enclosure.

It serves two purposes: to protect the power plant from voltage fluctuations in an area with an unstable power grid, and to enable operation on an external battery for years without being connected to the site's power grid.

The connection is made using a standard plug; a terminal block adapter is included.

Ajax has renamed this product "6V PSU (Type A)"; it is the same module.
