Replacement adapter for VVX desk phones

This 15 W Polycom SPA015A648US adapter supplies 48 V at 0.3 A to VVX 300, 310, 311, 400, 410 and 411 business media phones. It accepts a universal 100 to 240 V input at 50 to 60 Hz. The unit is a genuine OEM part manufactured to Polycom specifications.

Steady 15 W output under continuous use

The adapter maintains its rated 48 V 0.3 A output during extended operation rather than only in brief peaks. Built-in safeguards protect against incorrect voltage, short circuit and internal overheating so the connected phone receives stable power throughout the working day.

Cool and quiet in normal operation

With a modest 15 W load the adapter runs at low temperature and produces no audible fan noise because it has no moving parts. The compact enclosure dissipates heat passively while drawing only 0.5 A from the mains supply.

Questions about this item

Does the 48V 0.3A adapter run hot or make noise when powering a VVX 411 all day?

The unit delivers 15 W at 48 V 0.3 A with no moving parts, so it stays cool and silent during continuous use.

Which Polycom phones already on my desk will accept the 48V barrel connector?

It is manufactured for VVX 300, 310, 311, 400, 410 and 411 models; match the 48 V 0.3 A rating on your phone’s label.

Will the 100-240 V input let me keep using the same adapter if I move a VVX 310 between UK and US offices?

Yes, the 100-240 V 50-60 Hz input covers both regions; only a local mains lead is needed.
