Ajax 31190.01.NC Replacement 220 V AC PSU for compatible hubs and ReX 2

The Ajax 31190.01.NC is a replacement internal mains power supply board for compatible Ajax hubs and the ReX 2 range extender. It replaces the original built-in PSU when the existing board has failed or been damaged.

This is a repair and maintenance component rather than an alternative low-voltage PSU. Once installed, the compatible Ajax device continues operating from its normal mains supply.

Is This Right for You?

This replacement PSU is intended for the following Ajax devices:

• Ajax Hub (4G)
• Ajax Hub 2 (2G)
• Ajax Hub 2 (4G)
• Ajax Hub 2 Plus
• Ajax ReX 2 Range Extender

It is not the replacement PSU for the original Ajax Hub, Hub Plus or ReX. Check the model of your Ajax device before ordering.

Why Choose This Product?

• Repair instead of replacing the complete hub: replace a failed internal mains PSU while retaining the compatible Ajax device.
• Designed for the existing enclosure: the board installs internally in place of the original mains power supply.
• Restores standard mains operation: suitable when a compatible hub or ReX 2 no longer powers correctly because its PSU board has failed.
• Useful service spare: suited to maintenance and repair following PSU failure, including power-related or surge damage.

Before You Buy

• Confirm that your device is Hub (4G), Hub 2 (2G), Hub 2 (4G), Hub 2 Plus or ReX 2 before ordering.
• This is an internal mains-voltage component and is not an external plug-in power adaptor.
• If you need to operate the hub from a battery or low-voltage DC source, choose the appropriate Ajax 6V PSU (type A) or 12-24V PSU (type A) instead.
• Disconnect the Ajax device from mains power before opening the enclosure or replacing its power supply board.
• Installation should be carried out by a suitably qualified technician or electrician.
