Ajax 12V DC PSU Power Converter — dedicated power adapter that allows Ajax Hub 2, Hub 2 Plus, and ReX 2 to be powered from a 12V DC source such as an existing alarm power supply or battery backup unit. The Ajax Hub 2, Hub 2 Plus, and ReX 2 have a specific power input requirement. This PSU converter bridges the gap when integrating Ajax into existing premises where a 12V DC alarm power supply is already installed — avoiding the need for an additional AC adapter or separate power run.
