Purpose and audience
This Polycom PSC18U-480 power adapter delivers 48V at 0.38A for compatible VoIP phones and conference units. It is intended for IT teams or home-office users replacing a lost or faulty supply for the listed Polycom models.
Build integration
The unit accepts 100-240V~0.5A at 50-60Hz input so it works on mains worldwide without a voltage selector. A power cord is included for domestic purchases; overseas orders receive the adapter only. The barrel connector mates directly with the target devices, freeing the user from hunting for a matching tip.
Thermals, noise and power
Rated at 18W output, the adapter runs cool enough for desk-top use with no audible fan. Internal protection circuits guard against incorrect voltage, short circuit and internal overheating during normal operation.
