In offices where PoE (Power over Ethernet) is unavailable—whether due to switch limitations, occupied ports, or network configurations—you need an external power adapter that delivers consistent, interference-free energy. The Polycom FSP025-DINANS (P\/N 1465-44243-001) is the OEM-specified 25W power supply engineered specifically for Polycom VVX color desk phones, providing a regulated 48V DC output at 0.52A to keep your calls clear and your system online throughout the workday.\u003c\/p\u003e\n\u003cp\u003eWhether you're deploying new VVX handsets, replacing a misplaced adapter, or building out a hot-desking setup with spare power bricks, this FSP025-DINANS unit matches the original power supply that Polycom shipped with many of its VVX models. It converts standard 100-240V AC wall current into the precise 48V DC required by your phone—so you can skip PoE injectors, avoid switch upgrades, and get your desk phone running in seconds from any wall outlet.\u003c\/p\u003e\n\u003ch6\u003eApplication Scenarios\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Office Workstations:\u003c\/strong\u003e When network switches don't support PoE, this adapter delivers dedicated power to Polycom VVX phones at every desk without relying on network infrastructure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReception \u0026amp; Lobby Desks:\u003c\/strong\u003e Front-desk phones must stay operational at all times.

Polycom VVX phone?\u003c\/strong\u003e\u003cbr\u003eCheck the DC input jack on the back of your phone. It must measure 5.5mm in outer diameter and 2.1mm in inner pin diameter. Then verify your model is in the VVX 300, 400, or 500 series list above. If your phone is a VVX 600 series, this adapter will \u003cstrong\u003enot\u003c\/strong\u003e supply enough current for stable video operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy can't I use this 25W adapter on my VVX 600?\u003c\/strong\u003e\u003cbr\u003eThe VVX 600 series features a larger color touchscreen and supports USB peripherals and video calls, which demand up to 14.4W of continuous power. While 25W theoretically exceeds 14.4W, Polycom's engineering spec requires a 40W (0.83A) power supply to provide sufficient headroom for peak loads, boot-up surges, and accessory power. Using a 25W adapter may cause random reboots during video conferencing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use PoE instead of this adapter?\u003c\/strong\u003e\u003cbr\u003eYes, if your network switch supports 802.3af PoE, you don't need this adapter at all. This FSP025-DINANS is specifically for environments without PoE—such as home offices, switches with no PoE ports, or locations where all PoE ports are already in use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this adapter safe for 24\/7 use?\u003c\/strong\u003e\u003cbr\u003eAbsolutely. It's built for continuous operation in business environments, featuring built-in over-voltage, short-circuit, and over-temperature protection. The fanless, silent design is ideal for noise-sensitive office spaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMy phone doesn't power on after connecting. What should I check?\u003c\/strong\u003e\u003cbr\u003eFirst, verify the wall outlet works. Second, confirm your phone is in the VVX 300\/400\/500 series (not 600). Third, check that the barrel plug is fully inserted—the 2.1mm center pin fits snugly. If the adapter feels warm but the phone stays off, the phone's internal power board may have failed.\u003c\/p\u003e\n\u003ch6\u003e \u003c\/h6\u003e\n\u003ch6\u003eThe Polycom FSP025-DINANS is a 48V 0.52A 25W AC\/DC power adapter, manufactured by FSP Group as the OEM power supply for Polycom VVX series IP desk phones. It carries Polycom part number 1465-44243-001 and is specifically compatible with VVX 300, 400, and 500 series models, including VVX 300, 310, 400, 410, 500, and 501. This adapter solves the problem of powering Polycom desk phones in environments without Power over Ethernet, providing a reliable, continuous power source for office workstations, reception desks, home offices, and enterprise hot-desking deployments. It is not compatible with VVX 600 series, which require a higher-current 40W adapter.\u003c\/h6\u003e","brand":"Poly","offers":[{"title":"Default Title","offer_id":50974374363383,"sku":"LM-BI1D17NYPFKJNOPY","price":53.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0939\/6512\/3831\/files\/fsp025-dinans-1465-44243-001-charger.jpg?v=1785393266","url":"https:\/\/oempowerus.com\/products\/polycom-fsp025-dinans-1465-44243-001-48v-0-52a-25w-ac-adapter-for-vvx-300-400-500-series-ip-phone-power-supply","provider":"OEM Power US","version":"1.0","type":"link"}
