Genuine Polycom 15 W adapter

This 48 V 0.31 A power supply is built for Polycom VVX 300 310 400 and 410 VoIP phones. It replaces the original PSA15A-480P unit when the factory adapter is lost or damaged. The brick delivers the exact voltage and current the handset expects. No configuration is required beyond plugging it in.

Worldwide 100-240 V input

The adapter accepts mains voltages from 100 V to 240 V at 50 Hz or 60 Hz with a 0.5 A draw. This range covers standard office and home supplies in most regions. A suitable IEC C7 or C8 mains lead for the local socket is needed but not included. The unit has no voltage selector switch.

15 W continuous output ceiling

The 48 V 0.31 A rail provides up to 15 W of regulated power for a single phone. It comfortably runs one VVX handset with display and PoE-class features active. It cannot power multiple phones or devices that draw more than the rated current. Overload protection will shut the output down if the limit is exceeded.
