[QUOTE="Eric Eskam, post: 73098, member: 2124"] Re: Firmware Upgrade Now that the prices have come down I always go for the "online", "double conversion" or similar terminology UPS's. They have dual inverters - one inverter charges the batteries, the other runs your equipment. [URL="http://www.cyberpowersystems.com/products/ups-systems/smart-app-ups/paragon-series/ol1000rtxl2u.html"]These[/URL] are my favorites right now - I especially like the rack mount models for when you do have racks to mount them in. You never have to worry about switching time since there isn't any! The next best thing are models that have active voltage regulation. Your UPS isn't going to be worth much if you get sustained voltage sags (how hard is that to imagine at an event or venue with temporary power that's probably overloaded?) and your batteries deplete and then the UPS just switches off. Units with LCD displays are very handy so you can see what's going on with voltage well in advance of it becoming a more serious issue. [/QUOTE]
