    Power Conditioner - Inverter - Temporary Power Supply

    Sign in to disable this ad
    Hello Friends

    I need some sort of a power conditioner for several Power Mac Desktops and other equipment. I live in a mobile home community where we experience frequent momentary power outages. In a split second the device would need to keep the computers from loosing power. I'm familiar with Furman and other companies. Anyone have any suggestions? Thank You!

    BTW I'm a 72 year old member in good standing under a new registration name since becoming ill. Wonder if anyone remembers my grateful correspondence under ENIGMACODE back in 2004-2006?

    Just go to the Best Buy website (or something similar), go to the computer section, and look for UPS. A bunch of options depending on your need and budget.

    Conditioning and protecting yourself from outages that last only a few seconds to a couple of minutes is the cheapest of the UPS solutions.

    As you'll see, the longer you need the power to last, the more expensive it gets, and rapidly.

    And if you dont get the power back on quickly the cheap ones wont power you up for long.

    We dealt with issues for years, large machines and many pc's....the building backup generator kicks on in 20seconds, that was too slow so after 10yrs they bought a $185,000 UPS to cover the 20seconds and its worked well.

    Still theres tools that have a $5,000 UPS to the smaller $400-$500 UPS systems that can handle a few pc's for an hour or two if I recall.

    The single cheaper battery ups ac strips cover one pc for a few minutes, dont plug the monitor or anything not needed into the strip will help some.
    Laptops come with batterys which is nice and buys some time too.

    How long are the power outages? If its a day or two....its probably not going to matter.

    Know your Total Current Draw before shopping will help...or be required. I bought a $400-500 one around 5yrs ago, if I recall I had to gather the current draw then figure the UPS time needed. A generator is needed if its going to be several hours to days of no power.

    Yeah, rereading your post, 'several' desktops and 'other equipment' sounds like a lot of juice, even for a couple of minutes. If it's only for a few seconds, that's a little better, but maybe not much, depending on the total draw. Like CC said, add up the total draw, plus the amount of time you're asking for, then go looking. You might have to make some hard choices about what you put on it. You could get several smaller ones and distribute them amongst your devices, but that's not really going to be much cheaper.

    The question I would be asking the community managers is why you experience these outages so frequently. That's usually not a good sign. Plus, that's hard on your air conditioners and refrigerators and freezers, as well as just anything electronic, but especially the ones i mentioned with compressors. They should get that taken care of.

    Also some UPS are regenerative too, so you are always running on ac power that has been produced from a battery and the battery charged from the mains, while others switch from one to the other when power cuts. These are quick, but not continuous. I can run two computers from mine, and over the eight years I've had it, it can manage less and less time on the expensive to replace battery, but it doesn't matter, I just need enough time if it's a real outage and not a momentary drop, to shut down properly to prevent data loss. I don't bother with the monitors of course, so my 500w limit is fine.

    This is the reason the place I work bought the $185,000 building UPS (it can last 45 minutes with current load...but we keep adding tools/machines to it.)
    The power outages were causing so much repair costs in pcb boards and its tricky because the parts might not fail for a day or week...but it was the power outages. We were on the end of some grid or something , so if the wind blew hard it seemed we would have power outages, if it stormed power outages...lol

    A transformer company tech told me transformers windings have insulation, fine insulation and power spikes weaken the insulation so Lightning and Power spikes damage the transformers in many small household power supplys but the transformers wont fail right away so often people dont associate the failure to the power-spike that happened a few weeks ago.

    Im no expert, the more I was involved with all this large power spike stuff...the less I knew.

    Hi Gang - Sorry for the absence - I'm disabled - Thanx for all the responses

    As indicated I'm 72 and have a solid background in the Trades. In reply to notCardio's statement: "The question I would be asking the community managers is why you experience these outages so frequently" - These breif interruptions are commonplace in many smaller Florida communities. Most times they naturally cause my router to loose signal until it reboots. Most people live with this. But for an editor using an older Mac Pro Desktop (with several externals connected) this could naturally create corruption etc. I thought perhaps someone out there might have some experience with actually owning a particular type of rack mounted power conditioner-power inverter? What I might do is protect the externals with ONE unit and the Desktop with another one? NO way I can afford 100K - I'm retired-disabled - There's every reason to believe I can use several units successfully to take care of those BRIEF outages ... again just looking for some ideas as to which one? I can always call B&H and discuss it with them - thanks

    I have both a conditioner and a UPS in my little music room to keep stuff up long enough for me to shut it down properly. The conditioner is mostly and adornment (I think) to keep clean power going to devices like the interface, preamp, monitors and headphone amp, i.e., those things that don't have the potential of leaving corrupted files in the wake of a power failure. External drives and the computer (an all-in-one iMac) are on the UPS.

    We had a spell where the power seemed to flicker when a dog barked loudly, and I finally called the power company, and they looked at it, and said "Oh, yeah, we see there's a problem out there." Came out and fixed something on their end which apparently their control system had flagged, but because it was short-lived, didn't bubble up to the top of their "FIX THIS" list. Cost me a couple years of backups, so I got a whole-house surge protector and UPS after that. Our power has been pretty stable since then, not surprisingly, so I'd start with a call to the power company and complain, if it hasn't been done already.

    Anyway, a whole-house surge protector is something that goes in your breaker box, if it's got a couple extra slots. Not that expensive, and a good first-line of defense. (Note, this discussion is for the U.S. I know most of the rest of the world is shaking their head about this right now.)

    A good home UPS is unlikely to be rack mounted because of the battery. My conditioner is a rack mountable unit (from Carvin IIRC) but I just have it on a box next to the UPS. The UPS is a basic home unit (Cyberpower 1350 something) I calculated to be big enough for my needs and had decent reviews. It's important to understand the limitations of units like this, and I always shut everything down when going away for any length of time, even disconnecting the UPS. Most of the time I'm around though so can respond to the beeping when the alarms go off.

    Hello Keith!

    Thanx for the detailed reply .... I already have surge protection attached to the meter box outside (an extra service provided by Florida Power & Light). I'd be interested in your Carvin Unit. Is that the same company that makes guitars & other stuff? Could you send me the model number please? So yes exactly my goal (like yours) is to: "keep stuff up long enough for me to shut it down properly"

    Thank You Keith!

    This is what I have. It works very well, and even managed to keep power up through those minor ripples that don't trigger the UPS either. But when the power goes down, this turns everything off and stays off, which is what I like, since when it does get flaky around here, it can go up and down repeatedly until it settles on one or the other.

    Some reviews remark on an electrical odor when new, which I do recall, though I got this and the UPS at the same time, and they both probably have some of that. Don't notice it anymore but it's been in place just over a yeaer.
