Do not disconnect UPS voltage installation Voltage drop "Lightning protector"?

updating: Okay, one of the sites explaining what and how the NTC works, says:

Most NTC makers suggest that a cool-down period of 30 seconds to a couple of minutes is needed

The question is, how much will my own doubt really consume? For the sake of interest, this is: Seasonic x-850 gold. I tried to search the manufacturer's website, but nothing is mentioned about the NTC.

Maybe I'm missing something? Or does this vendor work differently?

Binary may answer before they communicate:)

What do you recommend for TV, a pause of 10 seconds or 4 minutes?

Write down something interesting that returns the 10 connection seconds after the stream stabilizes.

Does this mean that a teller would have a fall he knows to pause 2 minutes after if the voltage is still not working?

"The protection socket has a delay mechanism that takes care to restore the connection to the electrical grid as 10 seconds after stabilizing the current to avoid damage to compressors and electronic cards."

Thanks

I finally ordered 4 air conditioners for minutes and 10 for seconds.

4 = better protection if the voltage falls once more at a time interval greater than 10 seconds. But even longer that the shield remains turned off (and maybe after a small fall that was not significant)

I also recommend considering whether the shield pays off:

- A simple power strip if a circuit breaker allows you to turn off the power manually easily, and if you do not use TV you can just turn it off .... so at least in this part of time it will be completely protected. For the time remaining the shield still pays off? (The protective price vs the price of possible damage and the likelihood that the damage will occur)

- You probably will not buy a shield on 200 NIS to protect your cheap Lube TV that you bought in less than 1000 ....

In some (most?) Shields each additional voltage drop resets the time so that if there are some falls in less than 10 seconds it remains off and it measures 10 seconds from the moment the last voltage drop

It's possible that not all defenders are the same, but the defenders I know are yes

I was contacted by Matlauer for credit details. You will know that there is also a dent with a minute delay. This means that you have to choose between several models: 10 seconds, minute, 4 minutes.
Strangely, it does not appear on the website of qtrade.

cxzvcxv I charge you for 5 NIS, shipping was 45.

: smiley1:

thanks for the effort.

The minute shield is another model of VDP / VDPS or another model of another company?

The NTC is one option of manufacturers to control the current, the most common, but not the only. There are also vendors without NTC and may have gold between them

In this case the NTC cooling time may be irrelevant.

But in suppliers that have a more complex circuit on the input voltage, there are also many more "silicon" components (MOSFETS etc.) that stand close to the voltage input in terms of circuit structure, and are therefore more susceptible to voltage blows than those that are more "inside" in a circuit. That is, the vendor itself may be somewhat more vulnerable than a simpler provider (which does not mean that it protects the hardware less well)

I would like to protect the carrier from several jumps and falls of voltage if they come in more than 10 seconds from the second (as sometimes happens during power outages) - that is, not all of them but only the first and after that the shield will leave it disconnected

agree. So now, when we have another factor in the equation; Shield with a minute delay. The question is, is there a need for a thin 4 shield? Will the silicon parts you specify and the average NTC suffice to cool down in one minute?

Where did the thin guard come from? It may protect a sample that we do not know (and it may have some drawbacks) that only accidentally appears in the store's catalog together if the VDP / VDPS?

A minute is the perfect latency time for NTC cooling. In anything unrelated to NTC, there is no "cooling time" section - other components do not have to cool down before they can work again

The consideration here is different (it also applies to vendors if NTC, but more significant in "advanced" suppliers that might include other vulnerable components that are not simpler suppliers):

In the IEC system, the high voltage lines (those that operate a town or city or area) are protected by reclosers - automatic switches that not only jump when there is short but also automatically restart after a while. The goal is to prevent long blackouts due to accidental shortness: say a branch of a tree flying in the wind and hit the wires. There is a situation where he just hit the wires and pushed them to one touch if the other to the other, and there is a situation that will remain stuck on the wires and a short continuous production. In this case, the recloser will disconnect the voltage. After a while - which can be a few seconds ... a few minutes it will automatically reconnect it - in case the branch has already fallen or burned, to prevent a power outage "just". Let's say the shortness goes on, within a few seconds ... A minute of the current on the branch stuck in the strings will turn into a huge spark and will jump the defense again. It can take 2..3 times until the defense jumps "for good" and the system alerts the IEC to manually repair the problem

As far as we're concerned, this means that power outages can be in the form of several turns and re-ignitions within a few seconds or minutes

Each time the voltage falls or returns, the large system of the electrical company (large transformers) and everything connected to it can respond to the falls / repetitions of the voltage in creating a surge. The defense from surges that these defenders give is low - they can not be expected to absorb the blow in a way that will provide significant protection. If the first (sudden) fall does not have much to do, but if the shield has a long enough delay it will remain off and will not be re-ignited when the voltage returns / falls again, thus potentially preventing further voltages from reaching the computer

Did your region have power outages like these - when the voltage falls and returns several times? If so - how long did the voltage fall and how long did it return between the falls? By this you can choose how much lag you need

I understand.

Well, for this time ... (I hope so) that the electricity will jump, I'm willing to wait longer (= 4 min) and make sure that the fault has passed.

I will thank you again 11010010110.

You helped us all with the information, without you this purchase would not have been implemented.

Say something came to you? ... They said next week, now it's "next week" .. Tachles checks the account and even "have not taken any money" yet ..

That is, it did not even leave their shop for delivery.

Is there information maybe, something that can help?

I'll call them on Thursday if I do not move anything ...

Very strange, for your information.
