Perfect, and solved all my problems! Packaging was great and neat and fit and worked perfect. I could not believe I could get this from Amazon, wow thanks for that. Problem solved in 1 day! Perfect product too!

Worked on my 3comm telephone.

WELL DESIGNED

This PSU worked well with a MokerLink (rated 802.3 af/at) 3-port multi-use PoE injector/2-in-1 PoE splitter/gigabit passthrough switch. I used it to split one (1) non-PoE port from a 48-port switch to become two (2) PoE ports, and that requires the use of a 48V DC power supply.The compact (2.8” x 1.5” x 1.25”) power supply has a 68-inch (5.67 ft.) long cord rated for worldwide use (100-240V AC input). Output is 48V DC at 520 mA.I bench-tested it with the MokerLink box, a 100-ft-long outdoor Ethernet cable, and an 8MP eyeball network cam, and the PSU worked like a champ- (see photo).Should you need one, it’s of good quality and among the inexpensive ones you’ll find here at Amazon.

I am reviewing the product "for Polycom Power Supply is Compatible with VOIP Polycom VVX Models" on 18 March 2023.This perfectly replaced the power supply for my Polycom IP 335 VOIP phone. Form factor, construction, and supplied power were all fine, and I expect this supply to provide me with many years of service.
