[QUOTE="Brad Weber, post: 30885, member: 114"] Re: UPS for ls9 The local SurgeX rep related a story about his having a SurgeX unit on his computer at home when they experienced a nearby lightning hit. He said that while their TVs, phones, etc. were fried even where they were on generic MOV based surge suppressors, since the computer suffered absolutely no damage he had a difficult time getting the insurance company to accept that it has been a lightning hit, much less that there was no need to replace the SurgeX unit since it would continue to provide the same protection. It's probably also worth noting that with UPSs you're usually going to pay more for true sine wave output versus stepped sine wave and for online/double conversion versus line interactive operation. Whether those costs are justified is something you have to decide. One thing to keep in mind with voltage regulators is that for undervoltage situations you trade off current capacity for voltage, the more the supply voltage drops below the nominal voltage of the unit the lower the current draw supported. Probably not an issue for just an LS9 but something to potentially consider if you have larger current draw loads. [/QUOTE]
