Product information

Description

Power adapter Yealink 115778 — universal EU plug, replacement power supply for Yealink devices is a replacement mains adapter designed to provide stable power to compatible Yealink products. The unit converts AC mains voltage to the required DC output for supported devices and is intended as a direct replacement for lost, damaged, or non-functioning original adapters. The adapter features a universal EU plug format and is suitable for environments where an original Yealink power supply is preferred to ensure reliable operation.

Advantages

This replacement power supply offers consistent voltage regulation and a form factor compatible with Yealink devices that accept the same connector and electrical parameters. Using an original-design adapter reduces the risk of incompatibility or insufficient power delivery that can cause device instability, reduced functionality, or damage. The EU plug design matches standard European sockets, simplifying installation without additional converters.

Suitable for

  • Powering compatible Yealink IP desk phones
  • Replacing lost or damaged original power adapters
  • Providing spare power supply units for office deployments
  • Use in European installations with standard EU mains sockets

Key specifications

  • Plug type: universal EU plug for European mains outlets
  • Function: mains-to-DC power conversion for compatible Yealink devices
  • Compatibility: designed for Yealink hardware models that require this style of external power supply
  • Form factor: compact external adapter suitable for desktop or wall use
  • Safety: built to meet typical safety and insulation requirements for external power supplies

How to use

Ensure the adapter's connector and output specifications match the requirements of your Yealink device before connecting. Insert the EU plug into a suitable mains outlet and connect the DC plug to the device's power input. After connection, power on the device and verify normal operation. If the device does not power on or shows errors, disconnect immediately and check compatibility and outlet function.

Usage recommendations

Use the adapter in dry indoor environments and avoid exposure to liquids or extreme temperatures. Use only with devices that specify support for this type of external power supply and avoid using damaged cables or connectors. For installations requiring surge protection or uninterruptible power, consider additional protective equipment to safeguard the connected device.
