Yealink PSU-5V/2A Power Adapter

Overview :

The Yealink PSU-5V/2A is a dedicated power supply unit designed to provide consistent electrical input to various Yealink IP phones that do not utilize Power over Ethernet (PoE) for operation. This adapter ensures stable DC voltage, which is critical for the reliable performance of the phone’s processing unit, touchscreen, and network connectivity modules.

Engineered for enterprise use, this power supply adheres to strict energy efficiency standards. It serves as an essential solution for environments where PoE switches are unavailable or for workstations that require an independent power source to maintain phone uptime during network equipment maintenance or power cycles.

Deployment is intended for standard indoor wall outlets. It is compatible with a wide range of Yealink endpoints that require a 5V input. Always verify the voltage and current requirements on the phone’s base label before connection; using this with devices requiring higher power ratings may result in system instability or failure to boot.

Key Features :

• Genuine Yealink power supply ensures optimal device performance.

• Stable 5V DC output maintains consistent hardware operation.

• Compact design allows for easy integration into power strips.

• Short-circuit and over-voltage protection for device safety.

• Essential for non-PoE network infrastructure deployments.
