Buying a UPS

Recommended Posts

Not really sure best place to ask so mods feel free to move

I want to install a security camera setup at my house and looking to purchase a UPS to plug the recorder into them it occurred to me he good also to have the JVC projector plugged in as well if power goes out keeps the fan running long enough to do a proper power down

Any recommendations or ones to stay away from?

only looked at one so far from Jaycar around the $350 mark 

happy to pay $500 max 

thanks in advance for any and all advise 

cheers Muri

I kept an eye out for a secondhand APC UPS on eBay, you might find them on Gumtree as well?

The one I finally got was a 3000VA pure sine wave model, really total overkill, but for about $200, it was a bargain.

Nice to have when the power does go out, just as you say to make sure everything is shutdown properly.

Some / most APC UPS versions have a USB output that can be connected to a computer to monitor the UPS, that can be setup to trigger shutdowns of computers and other equipment if that equipment is capable of remote shutdown, this facility is built in to Windows.

My UPS sends emails as well if needed, it is ethernet connected, not USB connected.

 

You would need to get one that will run all the equipment that you require, add 25% of the equipment power requirements needed and buy a UPS that is above that value.

example, Projector 300W(?), CCTV system 300W = 600W + 25 % = 750W would be suitable.

See https://www.apc.com/shop/au/en/products/APC-Smart-UPS-750VA-LCD-230V/P-SMT750I

This this one is above your budget, but this is the sort of thing to look out for.

The APC UPS can also be monitored from a PC using the proprietary software from APC, "Powerchute", this works on my ethernet based system as well.

 

There are quite a number of other makes out there, I have just had good results with the APC types.

 

The Jaycar https://www.jaycar.com.au/1500va-900w-230vac-lcd-line-interactive-ups-with-usb/p/MP5207 looks OK but is a modified sine wave, it may cause problems with some equipment.

Software for monitoring etc is available but not for MAC, but may work with Wine?

I would avoid second hand UPS’ unless it has been used very briefly as the batteries deteriorate over time and could blow, leak or not charge anymore. Usually after 3 years of 24/7 usage.

 

Cyberpower and Eaton offer some of the best for money ups solutions in the market. Don’t bother with Jaycar units.

2nd hand UPS's are fine provided they're still cheap once you factor in the cost of replacing the batteries upfront. UPS batteries are only servicable for 3-4 years anyway so it's not unreasonable to expect to replace batteries over time. Since the OP was talking about security equipment, it's the same story with the batteries in alarm systems - they also need to be replaced every few years.

 

I've had a few Eaton UPSs over time and all of them (that's 4 UPSs in 2 locations) had horrible runtime if they were connected to a PC or a NAS. Run them without the USB connection and I used to get triple the runtime. Eaton replaced all of the units under warranty but it made no difference, it's their software that's the problem. I've since moved over to APC and have no such issues.

Don't get locked into the idea of replacing the batteries with more UPS batteries they  can be expensive. If you don't mind car sized batteries kicking around you can make the batteries external.

Ups batteries aren't exactly cheap $35-55 per battery and most smaller ups have 1 or 2 batteries. What if you purchase a cheap used ups that has other unknowing faults? A new 900va 540watt ups is around $150-170 brand new with warranty. Alarms use the same 12v battery but they last up to 10 years without a problem (speaking from experience as I used to be in the industry for consumer, enterprise and surveillance ups and battery supplies).

Ive purchsed 3 secondhand UPS's over the last 10 years. Only one needed batts, cheap enough to be cost effective from local ebay suppliers.

All 3 are still going, 3 brands to, Eaton, APC and Power shield.

Used for security system, 2 tv's and associated hifi equip. Allows you to power down safely if needed.

One tv is on an 1000va APC and will run the Samsung lcd for 30 minutes or more.

You can now get decent on-line UPS for $400-500 with a 1000VA rating ( Aprrox 800w).  These are the best type to have as they will clean and filer out all the crap off the mains as well as hold your devices on to allow for a suitable shut down time.  In-Line UPS work by converting the AC to DC then back to AC.  Particularly good for high end electronics such as your projector, high end stereo gear or computer systems.

 

AVOID second hand UPS.  Unless you know the history of the unit,  issues such are previous surge suppression,  batteries going dead short or being shagged is a costly exercise to replace.  Also you have no idea what power surges or spikes they may have been exposed to rending some the internal electronics suspect.

They maybe okay with the advice to sell product.  They are not good with warranty and their poor understanding of Australian consumer law.

Oh yes!

Product straight out of the box didn't work.  I was told that Mwave was not responsible and that I would have to send it back to the the agent at my expense for repair.  That was when I learnt a bit more about the law and my rights.

 

It is probable that Mwave is not unique.  Buying online has its problems.  Just be careful and know your rights and do not be bluffed.  If somebody tried what Mwave did to me now, I would very carefully explain my rights and if I didn't get due consideration then things would get exciting for all concerned.

OK, I haven't had any problems with them, as in, we have never been in an acid test.

 

I guess things are all Ok until they aren't.
