I've figured out enough of this to know that there's a fair bit of snake oil when it comes to these devices. From reading some of your posts, you seem to know your stuff on this. Problem is, I keep getting different information from various people and places.....and ALL of them seem to know their stuff!
I'm looking for all the opinions I can get. So why not APC? ( I am also considering a PureAV PF60) The H10 I'm looking at seems to have good numbers (just shy of 5000 joules...although I'm having a hard time finding a clamping speed for the MOV's), is UL 1449 compliant, covers all the incoming signal lines I need and many highly recommend the name. Audioholics even uses the H10 on their reference system. I've spent thousands on the equipment in my system and can't afford to replace if it gets melted. Even at $200, it would still be my cheapest piece of gear.
It's also not uncommon for me to come home 2-3 times a month and find the power has blinked off/on while I was gone (as evidenced by the need to reset all the friggin clocks!
) It's for this reason I'm looking at the H10, as it does voltage regulation duties as well as surge protection (the PF60 does not). The grid around here can be kind of flakey. Last, I like the idea of a rack unit for cable management.
Any input you can give is appreciated!
APC has some fine stuff and some poor values. You have to get into their better units to get good protection, and even then they don't give very detailed specs on their units. Many of the cheaper units that people are buying are a poor value in terms of surge suppression and/or do not have pure sinewave output for the regulation or UPS functions. Look carefully at the models that you are interested in. The H10 has only a 12A current handling and is not a pure sine wave output device. You can get similar, if not better protection without dirty UPS power, and a lifetime warranty for about 10% of the price.
Look for UL 1449 certification, three way protection with MOVs across all combinations of H,N & G, coverage for all incoming signal lnes to your system, maximum peak current ratings, lowest voltage let-through, and clear specifications for suppression on all lines. The H10 is probably OK for protection but it does not clearly state three way protection nor detail the clamping on the signal lines.
Much of the snake oil has to do with promoting the need for expensive filtering or regulation systems, and the need for a UPS. For most systems all that is needed is a good surge suppressor and careful checking of the grounding of all lines into the system. In most cases filtering makes no difference in the performance of the system and regulation/UPS are simply not needed in terms of protection at all. You can get at least as good suppresion for about $20 than what you get in a $200 UPS in many cases. On-line regulation without pure sine wave output seems silly to me, as these outputs are usually far noisier than unfiltered a.c. lines.
Why do you need a UPS? Other than a little conveinience in an outage, is it worth the cost, the need for maintenence over time, the risk of added problems in the system due to crappy power output, and the environmental consequences of all those batteries needing to be disposed of eventually? An then there is the added cost for something that you don't need...it puzzles me how people will search for good deals on a UPS when al they need is a decent surge suppressor and could save much more.
Two good values in surge suppression:http://www.newegg.com/Product/Produc...82E16812120408
is hard to beat, or for a company with a longer track record and excellent reputaion, and over/under-voltage cutoff feature,http://www.panamax.com/products.cfm?...il&id=249&ly=v
...and verify the grounding is solid and done properly on your system.
