Protectors No cables, White color please.

So according to their site:

3 של VDPS Protection of 10 seconds.

1 של ESP Protection of 4 minutes.

2 של VDP Protection of 4 minutes.

Total 6.

I will be happy to know the price we will receive before buying, in any case I will need shipping.

It does not matter if Or credit details.

Thanks :)

In the examination of the shield (or the absorption elements inside it), a high voltage blow is given - in a voltage, current, waveform and duration, and the shield's ability to shorten it

Uoc: The blow voltage given in the test. The shield is breached and shortened while absorbing the blow and therefore lowers the tension

Up: The maximum voltage that the shield will allow when it is in a "burst"

True surge protection has to be ranked, from a bigger and more primary shield to a smaller and more secondary shield. In general, Classes are like:

Class I - Direct absorption of lightning

Class II - Protection in a primary place in the system but not in the light of lightning strikes

Class III - Secondary protection in the system for sensitive equipment

A Class III shield has been tested with a small blow, such as what it is expected to receive if it has Class II shields that reduce the initial impact. If Class II protection is installed in the system, it reduces the risk of surge damage, and the Class III shield adds some extra point protection to the computer. Since home systems in Israel do not have a protective grade before the defender in the socket, the Class III shield alone is quite meaningless, along with the Uoc / Up data.

The installation of Class II protection has advantages and disadvantages, and because it is bigger, the advantages and disadvantages are greater - which still leaves the field pretty ambiguous and not black and white. I do not know if the bigger defenders are to recommend for or against. In Israel, I do not know if there is a problem with them or just because we are not sufficiently advanced

The advantage of a shield in the socket - the one that justifies the use of a shield (for a computer that is important enough / expensive) - is not its absorptive capacity (without a degree of protection above it is a lost cause), but the other defenses it can successfully conduct itself - High or too low, and the pause from the moment of disconnecting until re-connecting

The above data did not say anything about the other defenses. For the other defenses, you need to check whether they are in the specific shield, and what their data is (the voltage starting from it is considered too high or too low, the delay time, etc.)

IP is the level of opacity of the plastic box of the shield against intrusion of external bodies (the first letter after IP) and protection from water (the second letter). "2" means protection against medium-sized objects - you can not insert a finger into the hole of the socket, but you can insert a needle there. "X" means "untested" and, in our case, that the shield is not intended to be water-proof

Binary: What do you think of the blue and white refrigerator shield (Oz-On)? Is it worth anything?

I do not see protection here against a flare as you saw in qtrade

So I'm a bit skeptical.

In addition: Today there was a little wind and a power cut.

When the electricity returned: the red light was on. Until I hung up and put the plug back in, it did not change the current to the refrigerator.

Is that a bad sign?2vk18n9.jpg1z2zonn.jpg

Do not know the shield

The significance of the data (190 and 250 V) is that there is high and low voltage protection. There is also a delay. The components in the interior (the little circle, which is lm339 or lm324 or similar?) Look like the realization of such defenses. This puts him as the second defender I know if full defenses, alongside the Q protector

The only thing I do not like here is the sea movers standing in the top corner, it seems that without any thermal protection - though I might be wrong and there is a hang up or the MOVs themselves if 3 legs? - If there is no protection for MOVs, there is always a simple option to flip them away and leave it only as a high / low voltage / delay shield (which are also the defenses we are really looking for)

I found at home that I had another product of the Israeli company on the dishwasher.

By the way: the advantage of their possession over the imported: can be easily found and ordered on sites on the net. At the time, I ordered an Amperel (an online store in Bat Yam if I'm not mistaken)

And the screws are perfectly normal (so I guess Binary can fix himself if necessary).

The expectation is logical gates (some common expectations). How they are used to identify high / low voltage, pauses, etc. - depends on the rest of the circuit and the data of all the other components.

Let's say something about the tensions to which he responds? (Maybe from behind?)

Here too MOV has no protected. And the bigger it is the more dangerous in some cases
