Uninteruptable Power Supply

I'm pretty sure the UPS regulated the voltage aswell? Most of them advertise that they protect from brownouts and surges etc...

seemingly not, apparently it just runs from the mains untill the power actually dies. I have a pretty high end APC one, so if any of them do it I would guess that would.
 
you'd need something like a power conditioner or some other form of voltage regulation...

a ups will only help if your power dips out completely
 
I'm confused about the electric fence. Firstly how is it going to affect your electricity supply? Secondly I didn't realise farmers plugged them in to the mains! Most run off car batteries... Those that don't would run off a transformer so I can't see them affecting the supply either.

Have no answer to the low voltage but I'd suggest it has nothing to do with electric fences.
 
Which UPS is it?

From the little I know the idea is that the UPS kicks in when the input voltage is wrong. Unless the input power is so bad that the UPS can't charge its battery?


EDIT: Ohhhh. What the OP was on about isn't a proper UPS!

Some UPS (smart UPS comes to mind) offer power regulation of a kind, mostly overvoltage protection but I'm not sure that's what would help this person. It's something the electricity board should be looking at assuming you've had your own electrics checked by a qualified electrician.
 
There are two types of UPS. You need an 'online' UPS which powers the device from the battery, which is being charged all the time. Rather than one which only switches to the battery when power is lost.

Yea, your probably right. I just tought it might be, as it ticks at the same speed. I prosumed electric fences ran from the mains.
 
where would the ups get its power to charge when its kicked in due to a power outage?

as stated above, they are to prevent damage from a sudden unexpected outage, giving you time to properly shutdown and turn off equipment.

I was under the impression that they provided regulation and back up power. I was wrong.

It, won't help. I tought that the ups worked by constantly running the equipment from the battery, and recharging at the same time. I was wrong, so I have no use for it.

My power never cuts out, its just a bit dodgy.

That's exactly what an online UPS will do. What you've got isn't an online UPS - it's battery back-up only.

You need a higher model Back-UPS or a Smart-UPS. Look for 'AVR' in the specs - in your case, you'll need AVR boost. That said, I'm not sure a UPS will be able to keep up with a 4-second cycle - or if it does, it'll probably kill the battery fairly quickly.

I'd get the supply checked over - a UPS is at best a sticking plaster over something that could be more serious.
 
Thanks for the help guys, i'm off out. I'll have a think about it.
p.s. Is it the electricity suppliers problem? (you reckon I would have to pay to get them to come and check it out?) harsh times, money wise.
