15W 48V Polycom Power Adapter

This original Polycom SPA015A648US adapter supplies 48V at 0.3A for compatible Polycom devices. It accepts a worldwide 100-240V input at 50-60Hz and delivers a rated 15W output. The unit is designed as a direct replacement for the manufacturer part number 1465-43853-001.

Capacity and headroom

The adapter provides a steady 15W of power, suitable for devices that draw up to 0.3A at 48V. It will not support equipment requiring higher current or wattage beyond this rating. Builders needing more than 15W or a different output voltage must select a different power supply.

Thermals noise and power draw

The adapter includes safeguards against incorrect voltage, short circuit and internal overheating for safe operation under varying conditions. It draws up to 0.5A from the AC mains during normal use. No active cooling fan is present so the unit runs silently in typical environments.
