Avaya NTYS17DAE6 PSC18U-480 Power Supply For IP Deskphone

The Avaya NTYS17DAE6 PSC18U-480 IP Deskphone Global Power Supply is a dedicated mains-powered DC adapter that provides a fixed 48 V DC output to power individual Avaya IP deskphones when Power over Ethernet is not used or available. It is rated for 0.38 A (approximately 18 W), delivering enough current for typical Avaya IP phones in office environments to ensure reliable startup and continuous operation during calls. The unit uses a 5.5 × 2.5 mm barrel connector and is RoHS compliant, with Avaya describing the IP Deskphone Global Power Supply as compatible with 1100, 1200, and 2000 series IP phones across multiple regions. Identified by the model numbers NTYS17DAE6 and PSC18U-480, this adapter is commonly marketed as a genuine replacement power source for Avaya deskphones, offering a straightforward, region-agnostic installation path in deployments where a dedicated DC supply is preferred over PoE. Designed for broad, global use, it supports environments such as offices, reception areas, and conference rooms where a reliable, non-PoE power option is beneficial.
