Poly 48V DC Power Supply 25W – 120V AC Input

Product Overview

The Poly 48V DC power supply (86P04AA#ABA) is the 25 W external AC adapter used across HP Poly's 48-volt desk phone platforms, taking 120 V AC in and delivering a regulated 48 V DC output at 0.52 A. HP lists it as the power supply for the Poly Edge E5xx and Edge V8xx IP phone series as well as the CCX 5xx, CCX 600, and CCX 700 business media phones. This listing is the one to order when the requirement is stated by voltage rather than by phone model, which is how most procurement and facilities teams write a replacement power supply line item. The kit includes the power cord.

Product Description

Poly desk phones split into two power families, and choosing the wrong one is the most common ordering error on this category. The smaller endpoints — VVX 150/250/350/450, CCX 350, CCX 400, and the Edge E100 through E450 — use a 5 V, 3 A supply. The larger touchscreen and executive endpoints use this 48 V, 0.52 A, 25 W unit. Anything specified as "48 V DC, 0.52 A" for a Poly phone maps to part number 86P04AA, so a work order that names the voltage rather than the model can be filled from this page directly.

On the Edge side, the supply covers the E5xx series — including the Poly Edge E550 PoE IP phone, which is sold in a PoE-only build that ships without an adapter — and the Edge V8xx series. On the CCX side it covers the Poly CCX 600 Open SIP business media phone and the Poly CCX 700 video desk phone. If the deployment is specifically CCX 500/505/600/700 or Edge E500, the same part is also listed on our Poly 25W power supply for CCX and Edge E500 page.

Practically, this is an inventory and remediation part. IT teams standardize on PoE-only phone SKUs wherever the access layer supplies power, then buy this adapter only for the desks, reception counters, and huddle-space credenzas still on legacy switches. Because it is the OEM supply rather than a generic 48 V brick, the barrel tip, polarity, and regulation match what the endpoint expects — relevant on phones running a color touchscreen, an attached camera, or expansion modules near the 25 W ceiling. It is a self-contained external unit with an IEC power cord, so it mounts in a grommet tray or under a credenza and consumes no rack space.

Key Features

• 48 V DC / 0.52 A Output — Matches the power specification of Poly's 48-volt desk phone platforms, which are not compatible with the 5 V supply used by smaller VVX and CCX models.
• 25 W Rating — Carries a color-touchscreen phone with an attached camera or expansion module without running at the edge of its capacity.
• Broad Poly Coverage — HP lists it across the Edge E5xx, Edge V8xx, CCX 5xx, CCX 600, and CCX 700 families, so one part number covers a mixed desk-phone estate.
• Fills the PoE Gap — Powers phones at desk positions served by access switches that do not supply Power over Ethernet.
• OEM Component — Preserves the connector, polarity, and regulation the endpoint is designed around, unlike a generic aftermarket adapter.
• Power Cord Included — Ships complete, so no separate mains lead has to be sourced for the install.
• 120 V AC Input — Specified for North American commercial power.
