Hi Babu, Check out Halo http://www.haloelectronics.com You may have to call them because I don't see it on their web site, but they offer Ethernet transformers with reinforced insulation. There is also this http://www.pro-tek5.com/pdf/isolator.pdf Brian Melewski Staff Design Engineer Plexus Technology Group -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx] On Behalf Of Babu R-TLS,Chennai Sent: Thursday, June 18, 2009 10:18 AM To: si-list@xxxxxxxxxxxxx Subject: [SI-LIST] Ethernet transformer with 2500Vrms Hi, I am looking for an Ethernet transformer with 2500Vrms isolation between input and output section. But when I look broadly I am getting transformers isolated for 1500Vrms maximum. Can some one tell me why the Ethernet transformers are limited for 1500Vrms isolation? Also it would be great if I am known with manufacturer detail who provides 2500Vrms isolation.
