    How long will my ups hold up

    Depends on how much power the load draws and the size of the battery.

    Anybody do ups repair?

    Sorry it took so long to come back, I changed my email addy and so I didn't get the notification. Anyways, as for the electronics book, if you mean a good one covering both basic and advanced principles, hows about; Electrical Circuit Theory and Technology, by John Bird? I'm not so sure that...

    Calculating which Generator to use

    General rule of thumb is make the genny double the UPS size.

    Anybody do ups repair?

    Not sure who can help but we need more info. You've not mentioned what UPS you have. The fuses that go, are they actually the battery fuses?

    overload tone but no warning light

    I would suggest another problem. Does it still do it with no load at all connected? Maybe you have a battery fault. How old is the unit?

    True Online UPS that won't break the bank?

    Not sure what's happening here. If your AC is still causing problems then you may want to get a sparky to check it out. A fault somewhere could be causing your issues. The front end of your UPS, assuming it's true online should block mains bourne interference from what appears at it's output...

    True Online UPS that won't break the bank?

    Well hello mate. I'm in the industry too, (Chloride).

    True Online UPS that won't break the bank?

    Yup. Depends how you choose to look at things though. An offline UPS is more efficient, (whether the money you save due to that is worth it or not I don't know), They have two main types, ones where the inverter runs off load until needed or one where the unit has enough capacity to keep the...

    True Online UPS that won't break the bank?

    The UPS beeping during heavy load puts forward one of two scenarios. First, (if the heavy load is on the UPS), is your UPS is too small. Second, (if the heavy load is on the site), then it sounds as if the high current draw is causing the supply voltage to drop and the UPS goes on to...

    True Online UPS that won't break the bank?

    Andrew, I don't agree that the statement 'UPS powered kit should be run on batteries all the time' is true. A conventional UPS topology means that the UPS has the power running through it at all times. It doesn't actually 'kick in' as is usually wrongly claimed. The supply comes into the...

    True Online UPS that won't break the bank?

    I thought true on line was the standard design. Unless the unit is small or transformerless I suppose. Perhaps the unit you have is too small.

    True Online UPS that won't break the bank?

    Wahnula just because a UPS is a true online doesn't mean it is running on the battery all the time - I don't know of a UPS that does. I assume you mean a unit that runs as you say on line and not in bypass with a switch to inverter when the need arises. You may have a problem with the UPS...

    file name in mac osx 10.4.9

    Or, if you have a file/folder that you want the path of keep a terminal window open and drag the item onto it. A much easier way and it means you can then copy and paste the text for long path names that are buried many folders deep.

    Support with 2 UPS in the same face

    I don't think the difference in Phases will cause a problem for your load. I have been to many sites where their servers, (with dual power supplies), run from completely independent sources. This is assuming that the loads are not paralleled in as such and are single phase. I do wonder tough...

    Harsh Environment UPS

    Just remember though. Although your UPS will be fine under these wide temperature variations >Your battery will not.
