Genuine 18 W Polycom adapter for CCX310 and CCX600

This Polycom PSC18U-480 power adapter delivers 48 V at 0.38 A for 18 W total output. It is manufactured by Polycom specifically to power the CCX310 and CCX600 VoIP IP phones. The unit accepts a universal 100-240 V input at 50-60 Hz and includes a power cord. Safety features protect against incorrect voltage, short circuit and internal overheating.

Replaces a lost or faulty original supply

The adapter is a direct replacement for the factory supply shipped with the CCX310 and CCX600 models. Swapping to this genuine unit restores the correct 48 V 0.38 A profile when the original brick is damaged, misplaced or no longer holds regulation. The jump is worth it whenever the phone shows power-related instability or the original adapter is physically broken.

Verify the phone model and local mains cable needs

Confirm the handset is a CCX310 or CCX600 before ordering, because the 48 V 0.38 A output is tailored to those devices. Check whether your region requires a specific mains lead, as overseas purchases may ship without a power cord. Ensure the AC inlet on the phone matches the connector on this adapter.

Questions about this item

What connector does the PSC18U-480 use to plug into a Polycom CCX310 or CCX600 phone?

The adapter terminates in the proprietary round DC jack that fits the power input on Polycom CCX310 and CCX600 VoIP phones.

How do I connect the included power cord to the PSC18U-480 brick, and what mistake should I avoid?

Plug the IEC C7 figure-8 cord firmly into the brick's recessed inlet until it clicks; the common error is leaving the cord partially seated, which causes intermittent power.

When should I consider replacing the PSC18U-480 adapter?

Replace it if the output voltage drifts from 48 V, the unit becomes unusually hot, the cord shows fraying, or the phone fails to power on reliably.
