Hi GZ'rs again.

 

Now that I work from home I'm starting to see some issues with the wiring in my house.

 

It seems 50% of my house is wired up via one cable run, Laundry, 1/2 my kitchen and my office.

 

What happens is that several times a day my monitors will blank, as something turns on - dishwasher, washing machine or dryer I expect.

 

It's not a disaster, but it's very annoying.

 

Everything that has capacitors in them - phone charger, surface dock, even my soundbar is fine - It only happens to the monitors. To be fair they are older, and I brought them second hand however they work perfectly - other than this.

 

I don't want to spend a lot of money fixing this, so I was thinking - If I get a secondhand line interactive UPS (and not care about the battery) would this solve the problem?

 

UPS keeps the voltage steady, monitors stop blanking....or would I need one with batteries in good condition?

 

Was looking at this as an example: https://www.trademe.co.nz/computers/peripherals/ups/listing-2275523130.htm?rsqid=770806f66a7747cc89952777a60767bf-016 

 

Edit: made link work

Mine do this every time the clothes drier changes direction. It's annoying but I just ignore it. I have a UPS not plugged in I could test it with, an older Dynamix unit.

I believe you are referring to an ONLINE UPS, where the UPS is supplying power from its inverter 100% of the time and power issues on the supply to the UPS don't get through to the UPS load (your monitors).  Online UPS are typically more expensive.

 

A Line Interactive UPS only 'interacts' when there is a problem (power failure, or over/under voltage) and you'll hear it 'click in' when it is doing its work.

Yeah dual conversion UPS or a power conditioner would help cover the sags, You might also want to get a sparky in to see if you could isolate the laundry/kitchen circuit into a separate circuit as that would help with alot of things in general





Most problems are the result of previous solutions...

A test would be great if you can.

 

Don't want to buy stuff if it doesn't work.

 

 

 

It never used to bother me, but now that it happens 'enough' it's pretty frustrating.

Right - that's annoying, as the cheapies all just appear to be line interactive.

 

 

 

Last time we had a sparky in his response to my ask was that slight whistle through your teeth as you intake a breath - implying money...…….

 

So really just after a cheap good enough solution as it doesn't seem to bother anything else

You'd be looking at around $500 for a entry level dual conversion. Have a look at the Vertiv GXT series

That trademe one I listed is $50 with dead batteries, and appears to be online.

 

That looks good to me.....?

Dead battery will make it either not kick in when needed, or it will kick in then power fail.




Chorus has spent $1.4 billion on making their xDSL broadband network faster and even more now as they are upgrading their rural Conklins. If your still stuck on ADSL or VDSL, why not spend $195 on a master filter install to make sure you are getting the most out of your connection?

It's really about power conditioning - not actually using it as a ups.

 

When one of my appliances kicks in my monitors flick on and off. I'm thinking the conditioning aspect of the ups would deal with that. Would that work?

I'll try to remember to do this in a few days, won't have need for drier before then. My UPS is a Dynamix one I got for $20 from a guy who just wanted to get rid of it, battery works ok, but not sure if it's line interactive or not.

 

Seems like a bit of a waste of money to get a UPS for this to me, unless it's doing it constantly.

4 - 5 times a day, every day, and I work from home. It's one of those things that get under your skin.

Back in the startup days of Home theatre, before larger power and in-built protection was a thing Amps/speakers use to be quite fussy in this way.

 

My fridge or Microwave would go, and off would go the AC3 decoding (or pops in speakers). 

 

The solution short of re-wiring was add a ferrite coil here and there, And a filtering powerboard - not your every day over-priced and hyped feel-good purchase.
But an active device that did a job I think driven on small CAPs and switching mosfets (it's been un-phased when the CFL lights and alarm clock browns out)

 

Can't see any priced around the $120 mark anymore (all a lot more) but after I got one, Issues be gone! So there is such a thing that *may* help your case in small format form. It probably depends on the amount/type of interruption being caused

 

This seems to be about todays equivalent.

But take that particular model with a grain of salt. Especially with claims of "Can also improve computer gaming speeds and fix internet dropout"

That sort of thing could be a go. However I have seen $20 boards with 'power filtering' as a feature.

 

This seems to be the sort of thing ( a bit cheaper) https://www.jaycar.co.nz/10-way-home-theatre-surge-protected-powerboards/p/MS4033

I've had half-a-dozen UPS units fail in various ways, just find them too much hassle now. However, I have a couple of APC Line-R 1200VA units that often manage to keep equipment up through brownouts or fairly sustained undervoltage.

Power filtering wont help here as it sounds like when heavy devices come online he's getting momentary voltage sags. Unless these boards are coming with massive capacitor banks they wont help with sags.
