Which Polycom phones does the 1465-43853-001 power adapter work with?
It is designed for Polycom VVX 300, 301, 310, 311, 400, 401, 410, 411, 500, 501, 511, 600, 601, and 1500 business media phones, as well as SoundPoint IP 450, 550, 560, 650, and 670 desk phones. Is this adapter compatible with the Polycom VVX 150, 250, 350, or 450?
No. Those newer-generation VVX models use a 5V power adapter (such as 2200-48872-001 or 1465-48871-001), not the 48V 1465-43853-001. Using the wrong voltage adapter will not power the phone and may cause damage. What is the output voltage and current of the 1465-43853-001?
It delivers 48V DC at 310mA (0.31A), matching the Polycom OEM specification for the compatible VVX and SoundPoint IP phone models. Is the 1465-43853-001 the same as the PSA15A-480P?
Yes. PSA15A-480P is Polycom's manufacturer reference model for this adapter, and 1465-43853-001 is the Polycom SKU/part number that ships under that model designation. Do I need this adapter if my phone is powered over Ethernet (PoE)?
No. If your Polycom VVX or SoundPoint phone is connected to a PoE-capable network switch, the switch provides power over the Ethernet cable and an external adapter is not required. You only need this adapter if your switch does not supply PoE. Is the wall power cord included with the adapter?
The power cord is not confirmed as included and is typically sold separately (region-specific: NEMA 1-15P for North America, Type G for UK, etc.). Verify with the seller if you need one included. Can I use a generic 48V adapter instead of this OEM Polycom part?
A third-party 48V / 310mA adapter with the correct barrel connector may work, but using the OEM Polycom 1465-43853-001 ensures full voltage/current compliance, safety certification, and reliability with no risk of damaging the phone. What should I check before buying the Polycom 1465-43853-001?
Confirm your phone model is on the compatibility list above, verify you do not already have PoE available at your desk (which eliminates the need for an adapter), and check whether you need a region-specific power cord ordered separately.
