[QUOTE="Peter Etheredge, post: 7360, member: 58"] Went on an interesting service call today. HUGE house with an expansive Crestron system (controlling a bunch of TV's, whole home SWAMP distributed audio, and HVAC) that seems to crash about once a week and need to have its power cycled to work. My predecessor had been to the site a dozen times and had gone through the coding with a fine toothed comb and all seemed to be well. At one point one of the SWAMP units had been RMA'd as have a few of the TV's. This left me wanting to check the power situation as soon as I arrived as the home is in a very rural location. Sure enough at the wall I get a reading of 130 vac. I also get the same reading out of the Surge X (provided by the lead A/V contractor - we were just hired to program and consult on the control system) unit that the Crestron is plugged into. Looking at the spec sheet for the Surge X [url=http://www.surgex.com/products/sx1115.html]SurgeX - Products - SX1115R, RT, RL Surge Protector / Power Conditioners[/url] it seems that it only trips at closer to 145 vac. I'm thinking that the Crestron probably wants more stable power and for the time being had them plug it into a spare UPC they had laying around, just to see if things run smoothly this week. If that fixes it we can get a nice rack-mount UPS to cover the control system HOWEVER my question then becomes what do I do about the SWAMP amps. In any other circumstance I wouldn't even dream about using a UPS on an amplifier but would a really beefy one (or two) be my only option in a case like this? What about a voltage regulator instead [url=http://www.furmansound.com/product.php?div=01&id=P-2400AR]FurmanSound.com - Pro A/V Product - P-2400 AR[/url] Some other type of product I'm overlooking? Oh I should add that there are a total of two Swamp amp/control units each drawing 12 amps at 120v. [/QUOTE]
