Mine does.
If you mean an electrical buzzing noise along with the cooling fan kicking in?
It does also have a beeper that I'm pretty sure you can turn off or on.
No need to react - connect the USB port to your PC, and configure the power options to shut down automatically when battery capacity reaches 20% or so. The whole shutdown process is automatic.
Great prices. Looking for a Pure Sine one though, any of Eaton's pure sine?
I have several of the Cyberpower pure sine wave ones. They are reliable so far.
sadly the sale today on ebay doesn't have great prices on them. Looking for one to support a 850W PSU (looking at 5-600W expected max load), any recommendations - 1300VA or 1500VA?
You can always make your own using Victron Muilplus and any battery type you want.
@REDTUTE: Cheaper just to buy a AC-DC with charge controller for the battery type of choice and a separate pure Sine inverter. Victron is a rip.
Look at hardware that comes from the same factory with same components that cost about half:
Victron -> Fangpusun
Redarc -> KickAss
@plague69: It's not the same they have tried to copied there products with cheaper internals inside.
Try installing some cheap shit in something that's critical in a house or a boat and see how long it's lasts.
I'm not sure any cheap Inverter chargers do ac transfer while Seamlessly changing from charger to inverter all while keep with in a set AC amp limit set to whatever is needed from the Gen set.
@plague69: That's not how this works - when you buy the "same factory" products, they usually have cheaper (worse) components inside, and/or they failed the QC checks of the real badged products.
They're not equivalent to the badged products…
Whats the benefit of Pure Sine ?
Apologies, didn't mean to dirty the post with this. For highly sensitive appliances Pure sine is recomended.
But for most applications Pure Sine would not be of value as you would only be on the UPS for minutes to just safely shut down.
My particular need is for a Pure Sine (I think) but these prices are nice and I have upvoted!
Pure sine gets its key advantages when you're actually powering something with AC.
A desk fan for example will behave differently on square wave, than true sine.
However, a computer, or a modem, or a TV, or a phone charger; anything that has a secondary transformer turning the AC back into DC, will get near zero benefit.
SOME transformers can run a little warmer dealing with square waves, so you don't want to use these as a hack off-grid solution for multiple hours on battery; but since most people will run them for only single hours over their products lifetime, the risk of problems is hardly even worth mentioning.
I have one on my TV+HTPC, one on my server, and one on my modem; so when the power goes out, I lose nothing of entertainment nor work value :D
I assume @archieduh is running some sensitive AC lighting, or perhaps an oscilloscope? Something where AC noise is going to throw off the results.
The APC units are great - https://www.ebay.com.au/itm/144028701654 for example, with new batteries 👍
how much will it cost annually to run one of these?
The UPS itself will be working in a 'pass-through' mode most of the time. It does not consume much electricity at all.
Most of the cost will be replacement of the battery a few years down the track if you want to keep it.
They tend to chew 5W an hour, roughly.
So around the $10-20 mark a year (asssuming you get ultra cheap off peak rates).
It'll differ based on your energy plan.
The Eaton 5E 650VA UPS is a little cheaper for $99.08 at Computer Alliance (inclusive of their Paypal surcharge) using coupon CA10 which provided 10% off and free shipping for me from https://www.computeralliance.com.au/650va-eaton-5e-650i-ups-…
These ok to use with a powerboard to extend the sockets for low power devices like modem, router, switch/hub? Presume so. Main reason for getting one for me is to ensure network and internet access during a blackout.
Thats why I got one today. I am going to use it to power my UnRaid server along with Fibre NTU, router, and a Unifi switch.
I went with the 2000VA model for extra capacity.
Net may still be down during blackout depending on access type: https://www.nbnco.com.au/learn/what-happens-in-a-power-black…
Yeah I got FTTP, so we should be fine as long as UPS stays up.
Yes, but try and use a 'dumb' power board, as the MOV's on cheap surge protection units can throw off the load sensing. They are a surge protector already.
Does anyone know how many outlets are there in Eaton 5E 1100VA UPS? Searching from google shows 3 or 6 outlets.
The 650VA and 850VA have 2 outlets,
The 1100VA, 1500VA and 2000VA have 3 outlets.
Thanks mate, I'll pass as i need at least 4-6 outlets.
Plug a power board into it?
@johnyBgood: Bought the CyberPower Systems BR1000ELCD BRIC Line Interactive UPS instead, currently discounted from Amazon.
The buzz on these are louder then normal cheapish UPS
Can you stack UPS?
Get two and plug them into each other. Endless uninterrupted supply!

Do these buzz continually when the power fails so that I can react ?
