Do you prepare for a power outage?

Yes I remember. They made a mix of good stuff like Land Cruisers and poor quality stuff .
Today, our 2 road vehicles are Japanese… Mitsubishi Lancer wagon and Toyota ute… but I still love the old deregistered Landrover…some think British vehicles are poor quality too. A lot of them like Austin or Morris were very troublesome, to say the least.
One thing the Japanese did was fix oil seals… we dont have oil leaks today… I even fixed oil leaks in my Landrover… by putting in modern double lipped seals.c

Malaguti, Brixton are on sale here, but suffer with poor quality paint and chrome finishes but it does not help most I see are stored outside and subject to sea conditions close by.

It used to be all british bikes leaked oil, no matter which make or model.

Japan is well known fir quality, but not every model is built in japan now they outsource so much so like many things never mind the quality feel the width

Hi all and thanks for your latest replies, :heart:

@callpaul.eu :

No need to be sorry, Paul.
I think it´s always best to consider every possible scenario (even the unlikely ones) before making the ultimate decision to buy any item.
I´m grateful for any information I can get. :smiley:

O.K., I get it now. Buying from a well-known brand ensures the highest possible quallity.

One thing about Chinese brands though:

We were already discussing the “Eaton 3S550DIN” (see also here).

Eaton seems to be a Irish firm but on amazon they say:

Herkunftsland ‏ : ‎ China

i.e.: “Country of Origin: China”. :astonished:

I´m confused. Is the item to be trusted or to be avoided then :question:

Thanks to @kovacslt , @nevj , @daniel.m.tripp as well…

Many greetings from Rosika :slightly_smiling_face:

I think there’s about 5 or 6 UPSes in the house, one for pretty much every computer/server and then one dedicated to the networking stuff.

Batteries can get expensive, but it’s worth not having to reboot servers every time the power goes out, and it can happen pretty frequently here, depending on what’s going on.

Hi Doron, :wave:

thanks for the info.
So you´re using UPSes ( and quite a lot of them) as well. That´s good to know.

May I be bold enough to ask what make and model you employ?
Of course you don´t need to answer this question if it´s too personal :blush: .

Hi Rosika,

Various models of APC, but I wouldn’t necessarily buy them again. I’d probably go with the cyberpower models that have pure sine wave modulation built in. They’re better.

Hi Doron, :wave:

thanks so much for your very quick reply. :heart:

O.K., I´ve come across APC models during my research as well.
They seem to be of quite good quality.

I also heard about “cyberpower”. I´ll look into them.

Thanks. That´s another point to keep in mind. I would have missed that one.

That´s really great help. :+1:
Thanks again and many greetings from Rosika :slightly_smiling_face:

yeah, the pure sine wave modulation is just easier on whatever’s plugged into the UPS when it transfers over. Happy hunting!

Modern electronic devices (computers, laptops, phone chargers, etc…) usually have switching power supply built in, which first rectifies the AC power, then they work with a higher voltage DC. They don’t benefit from pure sine.
But old-school power supplies, which first tranform the AC to a lower voltage, then rectifies, after that filters to get a smooth DC: they do benefit: much less power loss on the the iron core of the transformator, because of much less overtones in the input AC.
Same applies to AC motors, they really do hate the trapezoid wave.

Hi László, :wave:

thanks for the background information.

I am amazed at your great knowledge. I wouldn´t know the first thing about it. :blush:

I never knew that, I always thought that pure sine wave meant if you look at the power coming from the AC line on an oscilliscope, it looks one way, and then coming from a non sine wave ups it looks kinda malformed/dirty, but with pure sine wave that’s not a thing.

Exactly, the most cheap implementation used long ago simply outputted square wave, later they used “modified sine”, which in practice means the trapezoid wave.
The pure sine output is really clean, it is the most sophisticated implementation, but is more expensive.
For a whole household generally the pure sine is the best choice (say as the inverter for the solar cells), because in the household many inductive loads may be present: vacuum cleaners, hair dryers, lawnmowers, coffee grinders, and so on, everything with AC motors.
For switching power supplies, and pure resistive loads the waveform doesn’t matter.

Thanks! Sometimes I’m afraid of being the brainy smurf, and possibly kicked…

Just let me know please when I’m too much… :pleading_face:

Hi László, :wave:

thanks so much for the detailed information.

I gather the Eaton“3S 550 DIN” should be good enough for my setup.

  • Lenovo-H520e desktop PC,
  • LG monitor 22EA53VQ
  • and the power supply of the hub for the external HDD

I have to look at the cost of the UPS, too. :blush:

It has a european certificate of conformité so no matter where its made it should have been tested and certified correct for safety.

I know the mark but dont know this product so prefer not to recommend. Should be fine

In my place which doesn’t have super high speed internet or regular power supply, we used to have UPS + a small generator. The UPS used to give us like 10-15 mins time to safely shutdown computers and if there was need to keep the lights on longer, we’d krank the generator on :smiley: (Running computers on generators is a luxury btw! - fuel is expensive)

If you live in a urban area that is well connected, most likely the reason you’d want to have UPS is not to account for flaky network issues (power, internet etc) but to ensure that your computers don’t shutdown suddenly which could currupt your system etc.

Hi @HotTipoff4425 ,
We live about 15k out of town and have lots of power outages. We use a generator ( noisy things) to keep refrigerators and lights going, but I have never been brave enough to run the computer on generator power.

I think a laptop would be OK … run it on the battery, and charge the battery with it turned off.
But what should one do to provide clean power to a computer when the source of power is a generator?

Regards
Neville

I am probably not the best person to answer this but all I know is that we have a separate “plug board” that allows us to connect the generator directly to the entire home. That way pretty much everything in the home can be powered (in theory!). I am not sure what such a system is called though.

You are better setup than us. I have to run leads to each appliance.

I think modern generators produce nicely filtered power. I will check. Ours is old.

Quick search brought me here, “Transfer Switch” I think this is what that “separate plug board” could be… (I would just hire an electrician for this tbh :smiley: )
