Ajax 220V PSU for Hub/ReX
220V PSU for Hub/ReX: the original power supply as a spare
If the mains power supply of your Ajax Hub (2G) or ReX is faulty, the whole control panel does not need to be replaced. With the Ajax 220V PSU you only replace the power supply board and the system runs on the 230 V mains again.
The 220V PSU is the same 110/230 V~ power supply board that Ajax fits as standard in the Hub (2G) Jeweller and the ReX Jeweller, supplied separately as a replacement part. You use it when the power supply is defective or damaged, or when you want to connect a device that ran on a low-voltage board back to the mains. It is an official Ajax part and not a modification, so certification and warranty remain intact.

Installation
How to replace the board
Switch the device off and unplug it from the socket before you open the housing. The 220V PSU takes the place of the existing power supply board. Then close the housing, reconnect the hub or ReX to the mains and check in the Ajax app that the external power supply is reported again. It is a 230 V component: have it replaced by a qualified electrician or your installer.
The board is supplied loose in a zip bag, without a box or quick start guide. Store it in a dry place and hold it by the edges.
