Peace

Soon I plan to buy a new computer screen and speakers and realized that it is worth buying them protection against voltage falls etc.

By the way the rest of the electrical products is also recommended? Air conditioner washing machine refrigerator etc.

From what I've seen online there's a UPS or "lightning shield"

I wanted to ask for an explanation of the difference between them because I could not really understand and ask for a recommendation for UPS / "lightning shield"

I need protection only against jumps and voltage drops etc. UPS to give me X minutes Active computer without electricity does not interest me .. I'm looking for net protection no more than that ... so I figured I better fit "lightning shield" .. The problem there is a lot Such shields and I have no idea what to buy .. I will be happy to advice ..

Thanks

If you do not want backup (ie allow for sudden shutdown and loss of data that can happen, only protection as much as possible from hardware damage) your general direction is to protect the socket, such that disconnects the voltage when not in good working order

The protective capabilities of such a shield are limited: it can protect certain things, not everything, and not always

Approximately every such shield has components that absorb voltage surges. Do not expect them to be significantly protected - home electrical systems do not have gradient protection that starts from large shields instead of more primary, but everything that comes is supposed to be absorbed by a small shield on the socket. This is not going to happen - a high-level power surge that can harm your computer will usually pass the shield and damage your computer. Maybe he'll burn the shield on the road and maybe not

The best defenders have additional defenses - not from voltage surges but from high / low voltage and quick jumps. These are things that have a chance to protect them. A shield in which the other defenses work properly can protect the computer, especially from the phenomena that are going to happen at the end of the night - fast voltage drops, open-air, etc. that happen because of things that fly in the wind and damage electric wires

In addition, surge protection components can be significantly warmed when they absorb something, or when they receive high voltage over time. High-quality shields have a thermal fuse that cuts them off when they heat up, there are no quality shields and at worst they can go up in flames - and you would not want the shield to burn the house in an attempt to protect the computer

Until now the only shield where I've seen that things stand in place is the VDP and VDPS of Q protectors. For protection without UPS selects the VDP which has a delay of 4 minutes - should provide better protection from cases such as power falls and power failures that return quickly as during a storm

Possible problem: Sometimes the defender can also respond to small falls, such that would not create a problem if there was no shield. If this happens it will interfere with the use of the computer

Such a shield should work out if something like Max 8A, computing / electronics equipment takes much less than that

Other appliances - many of them are not vulnerable in a way that justifies the use of a shield. A large part of them are off most of the time, and neither is the need for a shield. The use of a large "non-electronic" shield is often unnecessary and helps more sales of shields and less protection of electrical appliances

For things like a refrigerator and an air conditioner, there is an advantage of shield protection - if there is protection from low voltage and a few minutes' delay. This will prevent the compressor from starting up against the gas pressure - which can cause it to simply remain stuck in the starting position and can be burned if the thermal protection inside it does not "jump" in time

First of all thanks for the answer ..

I could not find an online store that sells Q protectors and you have perhaps a recommendation for such a store in the Herzliya area / online store (also good ebay)? ..

I managed to find a similar shield from other companies (also they have a delay mechanism of 4 minutes)

What do you say about them?

I also wanted to ask if I'm connecting a splitter to this example: http://ksp.co.il/?uin=21240 (Or any other splitter) to such lightning shield that the splitter will become protected?

Such splitter can "swipe" a computer screen And a few other nonsense connected to him?

Thank you Thank you Thank you

I would like you to see exactly what the phenomena here are:

image.png

The normal voltage is supposed to be - 240V AC, which is an 340V wave

ac1.png

Lightning damage - the voltage jumps to the values ​​of thousands of V, and not always "immediate". No shield plugs into the socket, and no basic UPS has any chance of protecting your computer from it. Just too much energy

ac2.png

Small "surge surges", they can happen because of effects in the system of the electric company, or at the beginning and end of power outages. If they are high enough they can damage the computer, and a shield that plugs into the socket or UPS in many cases also will not be able to protect them

ac3.png

Voltage drops - the voltage simply disappears for a very short time and returns. Their ability to do damage is significantly greater when they jump quickly after each other (like several times when the light goes off and goes on). A shield that has a delay does not allow the computer to re-accept the voltage immediately after it has fallen, or a series of falls and repetitions of the voltage. After the first fall, it leaves the computer disconnected and waits until all the falls have passed before reconnecting

ac4.png

High or low voltage instead of 240V should be. The power on the computer is not built to receive 400V instead of 240V ..... Too low voltage can cause damage if it lasts long enough. A shield that has protection from these situations disconnects the computer and leaves it disconnected if the voltage is not within the permitted range

Great explanation I learned ...

I know that nothing will help in the event of a lightning strike (at least in a category that does not require a mortgage from the bank) .. My intention is to protect against stress drops (like what is happening now in the rain) .. Note that I always wrote a lightning shield with quotation marks because it is not really Anti-lightning shield .. This is simply the word that "people" uses :P

Do you know a physical store / store on the internet that sells the V protectors Q? (I could not find online ..)

From these voltage drops:

GPT models - no. They have some significant problems (assuming they have not fixed them yet - from outside the defenders look the same as the ones I know)

The one whose upper side is in the shape of ^ - does not know, the first time I see that there is a shield of this brand (although I already know the brand itself)

Hyundai - not familiar with this specific model

The splitter that Link has given to him already contains something of himself (and also what I have there I do not know). In any case, you can connect a splitter to the shield and thus protect everything that is connected

What is:

Do not connect this splitter electronics together if things have a large engine, a large transformer, etc. (such as an air conditioner or refrigerator). Motors produce power surges when turned off. If the shield disconnects the voltage (for protection), the resulting surge will go directly to the electronic things through the splitter

Do not go over the max 'shields or splitters are built to hold. Write them 16A, but realistically do not switch to 1 / 2 from that

OK

So I sent an email to Q protectors and asked where to buy .. I'm waiting for an answer ..

In any case is one of these

http://www.belshop.co.il/Product.aspx?pid=294

http://www.belshop.co.il/Product.aspx?pid=2022

Can it even come to mind or are they bad? ..

If I connect the same computer splitter to a speaker screen and a Router and a USB port No problem right? In a stretch of tension .. what you talked about things with an engine .. None of them have no engine ... so there is no problem to connect them together assuming I did not pass half of what 16A ... I am right?

I have seen on the internet that you once talked about the connection of the defender something with the NLE Can a brief explanation also on this?

Thanks :)

I dismantled one of them (I have , Can find if you are interested) - the circle inside is not different from that of the SC9 (the same PCB, only SC9 places 1 or 2 handles empty)

In SC9 there are some problems, and in my opinion serious enough:

- No high voltage protection. They build on the absorption components of the waves that will absorb even a voltage that is just high. The shock absorption components are not intended for this. If they put them low, they may respond to "just" high voltage (which is still in the 400..500 V), shorten and burn just. If they put them high, they will not give any protection from "just" high voltage. So they choose a middle value (430V), which is worse than 2 exams .....

- Surge absorbing components without thermal protection - just stand inside the plastic body. Worse still, they are not particularly high-voltage, so Open-air can bring them to extreme warming and nothing will break them up. I do not feel safe

- A design problem in low voltage protection probably means that sometimes the shield can not decide whether to turn off or turn on the voltage - it jumps quickly between the states, thus creating a series of voltage drops that will probably hit the computer much more than the low voltage it would get without The shield

Maybe those 2 shields I said I do not know are good ..... and maybe not .....

High quality speakers usually have a transformer, but it is not the size that can cause damage. You can say that all computer equipment can be connected to the shield

The consumption of computer equipment is fairly low, especially all the routers, etc., which consume the order of 0.2..0.3 A per unit. I do not think you'll get to 8A if your computer

LNE are the lines that come to the 3. The holes in the socket L (right phase), N (left), E (bottom). The absorbed surge absorber component Suppose that between L and E is a component that will absorb a power surge between the L and E wires

Yes I am important that we all be happy to the pictures It can be interesting to see how it looks from the inside ..

I realized then you only recommend the Q protectors I will wait for the manufacturer's reply http://www.qtrade-intl.co.il/ About where to buy ..

Okay fine so I only need one instead of four .. I'll connect the shield to the wall outlet and the splitter to the shield ..

How can I make sure I do not pass the 8A I'm supposed to plug in the power consumption of all the products I'm about to connect to it and see how much I get? How do I calculate the A .. After all, on electrical products registered a few watts they have not found that listed something on them A just a few watts are ..

For my part, I would be happy to see pictures of other shields that I do not know (inside of course). It's true that I already have a shield to point out that he is better than the others, but it does not make sense to me that from everything that is sold in Israel to only one company will be a normal shield .....

I'll send when I find the pictures

There is a connection between A and W but not direct:

Electrical devices have a power factor: a figure that links the W (true power) to the VA (simulated power). Real power = simulated power * power factor. Because the power factor is less than or equal to 1, the actual power is less than or equal to the imaginary power

The power factor depends on what is connected - for example:

Non-PFC power supplies (including small power supplies as of routers): 0.5

Passive power supply pfc: 0.7

Power supply pfc: 1

TRANSFORMERS: Depends, but suppose in the 0.5 region

Heating elements other than air conditioners: 1

Air conditioners: 0.9

Incandescent lamps: 1

Fluorescent lamps: between 0.3 and 0.9

The simulated power VA is simply V double A, where V is known - 240V

Example:

Find A of a computer screen that uses 50W

Suppose that the screen without PFC (worst case, today on many screens yes there is PFC). Supplier without PFC = 0.5 power factor

50W / 0.5 = 100VA

100VA / 240V = 0.42A

As a general rule, if you connect the entire "computer corner" (whether it's a home computer or even a heavy gaming computer, and without high-power stuff unrelated to the computer), you should not reach the 8A area. Computers do not consume even close to it

Will not really help you but:

I also looked for Q-Trade's voltage shields in the past.

In the company I was told that they are not selling at the point of sale to final customers but can only be purchased through authorized electrical equipment installers.

The last time I had such an installer (to install a new dishwasher) I asked him about this shield of tension.

He was glad to pull it out of the bag just wanted it 280 NIS .... (since this dishwasher, the voltage shield he offered also has a stay)

I believe you will be able to find one with authorized TV / electrical appliance installers, but they are cutting a very big coupon ...

11010010110 Thanks for the explanation - you are also familiar with the following protectors:

SC98P0P

SC98COM

SC98JAZZ

OM-QD-06

Question 2: The Rebbe sank that there was already a "Bilt Inn" shield in their midst. And you did not say you could buy a protector from the Governor of Q-Trade, which in the meantime is the only one recommended and to connect it to a splitter and that's how the whole splitter will be protected. My question is that I need a "sophisticated" splitter like one of these, or a "simple" splitter on 15. ?

First you said that GPT and HYUNDAI are not recommended with the defenders of: supco / waisbord / any defender with another delay to find .. because it really does not make sense to have only one shield in the market worth something ..
