Lots of folks provided very good suggestions and information. Here is a brief attempt at a summary. I only got a few sales folks hitting me up, so you are probably on your own to get in touch with most of these guys. Top recommendation: * Eltek/Valere seemed to be the top recommendation (3:1 or 4:1), though customer svc is rumored to have gone downhill since the acquisition). Large Plants: (1000A and more) ** C&C & Sageon (sageon: stand alone, not rack mount, C&C scales in 100A increments) Small plants: Argus (re: Cordex unit- management UI only works in IE, emails just fine, good chassis based expandability) [2:1 recommendation here] Tyco in the lower range Telect for unmanaged supplies/PDUs Lorain/Realtec makes nice equipment. Thanks to everyone for their input, I don't have much more detail from most of the responses so if you want a contact who is using this gear, I can try to make the introduction. Deepak Jain AiNET
