Avaya E129 SIP Deskphone Power Adapter

This AC power adapter is designed specifically for the Avaya E129 SIP deskphone. It delivers a 5V 0.8A output from a 100-240V input, making it suitable for standard mains supplies worldwide. The unit is supplied new and matches the original manufacturer part number 700507152.

Installation and Common Issues

Installation is straightforward: connect the adapter to a mains outlet and plug the output into the deskphone's power port. The adapter operates at 60Hz and accepts a wide input voltage range, so no voltage selector switch is needed.
