Well, you didn't spend much. I am thinking of something for a few dozen zlotys. I am thinking about the ever home strip. Anyone else have any suggestions?
I'm glad I didn't spend much! I bought a dozen or so of these security devices ... I checked more expensive solutions - safety strips and modules. I have been dealing with surge protectors for twenty years. I recommend that everyone use them to secure individual computers. I also use them in companies, in server rooms.
The R-20F has two varistors and two spark gaps, and in most solutions I have seen one varistor, very rarely two varistors and one spark gap. Knowing how much a varistor and a spark gap costs, it's hard for me to understand why I have to pay more than a few zlotys to an ordinary extension cord - because this is the maximum cost of the protections that I have seen in surge protectors.
If the R-20F does not suit you, I advise you from my practice: look for solutions costing more than PLN 100, maybe something from APC, Belkin? In the cheaper ones, I usually saw one varistor (costing +/- 1 PLN in detail). The filters used in the few power strips are also in the basic version.
You will get the greatest effectiveness of the overvoltage protection when you have the entire electrical installation secured, that is, in addition to class D protection (surge protectors), you will add C and B. If you do not have it, it may be worth expanding the protection.
If you choose something and be able to take pictures of the interior, I will be happy to see them.
I have just found such illustrations. In addition, I read on the Polish pages that it has a fuse or thermal fuses. I do not know if it has a thermal fuse, it does not exclude the fact that it has a varistor or vice versa.
No, it doesn't. Illustratively: the fuse is an overload protection - it prevents the flow of excessive current (Ampere). The varistor, on the other hand, after increasing the voltage (Volt) above the assumed standard, starts to act as a receiver and absorbs excess power, making a short circuit, which lowers the voltage. When the varistor makes a "short circuit" for a long time, the fuse should work to protect the cables (in the walls and the extension cord itself), cutting off the power supply.
I understand the thermal fuse as follows (and this is how it should be understood): the ordinary fuse must be replaced when it "blows", and the thermal fuse cools down and the strip can be used again.
Generally, you made me realize that the prices of surge protectors are too high. As you wrote earlier, varistors or spark gaps are a matter of a few zlotys and the rest is probably extra for the cable itself. When I buy a skirting board and I can unscrew it, I will see what's inside. So far I am thinking about the F9H400ep2M F9H410ep2M and F9A402ep2M strips. I see that you are on the topic, I have one more question. If I do not have sockets in such a surge protector and connect an ordinary extension cord to it for a dozen zlotys, will it be the correct extension of such a strip?
Long ago, when I had my first job, surge protectors hit the market and my friend became one of the main distributors. It was he who encouraged me to check what was inside and made me realize the relation between the price and the content of this product. Since then, I have been following what can be bought and for what money for professional reasons. If I were to buy one security device, what's there ... But at home, in my cell and on my plot, I already have almost twenty of them, and in the companies (where I worked / work) there are hundreds and thousands of pieces. Generally, each employee has a computer and a power strip ... Only in a minimum number of cases the number of sockets in the walls corresponds to the need, and the strips are used as end protection anyway - and I want it to be the best protection possible.
The rule is not to connect extension cords: due to the fact that this way also connects the protection pins, which may have a negative effect on their operation, and due to the possibility of drawing too much power (e.g. for a socket or cable). extension cord). The electrician might add something more, or deny it :-)
However, good strips have an overcurrent protection in the form of a fuse and are usually used to power electronic equipment with low power consumption. For this, the best protection is simply a thinking user Such a connection (strip-extension cord), however, provides overvoltage protection. I have connected equipment myself: http://jackiewiczowie.blogspot.com/2013/12/centrum-zarzadzania-swiatem-zasilanie.html In the first photo (and not only) you can see one surge protector and several extension cords - with the power the consumed rarely exceeds 500W, and I checked the protective connections with a milliohmmeter.
I am asking because the surge protector I want to buy only has four sockets and I still need five or six. Now I do not know myself whether it will be safe to extend such a strip with an extension cord.
What will you feed from it? Can you connect devices that do not have a security pin to the extension cord? - like some power supplies for monitors, laptops, chargers?
So yes. I want to connect an extension cord to the strip, which will be connected to a TV set, laptop, set-top box, modem, router and possibly a console and a player.
Please correct the post - regulations, point 3.1.13 [dzimi]
Estimates energy consumption: TV: 200W Laptop: 100W Decoder: 40W 15W modem 15W router 100W console 70W player I would not be afraid to connect the extension cord to the strip at home, especially since the F9H400ep2M strip you are proposing has a 16A overcurrent protection.
Light load. I still use them, although as described in the above links, I soldered all cable connections inside the RF-20F. For such a low price, I won't even buy such a nice case, not to mention the interior of this protection. I think very, very few people protect high-power receivers with them .
I'm coming back to the topic because I need a surge protector for my home again. Earlier, I bought a Belkin F9A402ep2M strip for PLN 70, which has an emi / rfi filter 43 db 300 volt varistors, thermal fuses and 918 J energy absorption. I was just looking at what is interesting now on offer and when I was about to buy the Ever Optima strip for PLN 30, which really has nothing interesting in itself, I noticed the Philips P54020 / SPN5044A / 19 strip for PLN 80. It looks like the energy absorption of this strip is 1800 J. Emi / rfi filter 58 db, plus mov protection, that is probably varistors. Such a good strip, is there anything here that I do not understand?
@ 3echo Of course it will protect, or at least reduce the consequences - when the electrical installation is under comprehensive protection, so RF-20F is the T3 protection class. Anyway, what does lightning mean? From a lightning discharge to a lightning rod installation, an element of a building, a nearby tree, a nearby and overhead power grid, a medium voltage network, an RTV antenna, a cable from an intercom, telephone, cable TV? Having comprehensive protection does not change the fact that during a storm I disconnect devices by removing plugs from sockets. And I combine this fact with the reliable operation of electronic devices over the years - experience tells me that a power supply not protected by surges of any origin lasts longer.
@ 3echo The red lamp indicates the presence of voltage in the splitter sockets, while the green lamp indicates the efficiency of the protective circuit. With very high energy overvoltages, the varistors may be damaged and this condition is indicated by the green lamp not lighting up.
One of them, when I put it in the socket, blown the fuse on the cage. Later, no lamp on the splitter was on. This copy will go to the complaint. And so they exchanged this one for a new one and so far the lamps are lit.
I bought mine on Allegro and probably also in Tesco. They had packages and on them a description, including the meaning of the lamps. For me, there was only one problem, a serious one: they could not withstand a long-term load of about 2,000 W. Still, I still think it is a good product. I use it, turn it on, turn it off, switch it. After my modifications, I also use high power devices all the time.
I gave this one to a professional electrician, because I did not want to go to the castorama again and I was curious myself what was inside that it was raining like that. I don't know anything about electricity, but he said something about cold solders, and he said that it was better than a cheap strip. So he confirmed what you wrote about earlier. Worth the price, for PLN 15. there is no better protection than power surges.
Such strips are no security. It can do more harm than good. Most of the equipment is perfectly capable of dealing with momentary surges in voltage. It is better to invest in impulse pin eliminators and installation lightning arresters for rail mounting and put in front of fuses. In any case, installation lightning arresters will in many cases protect the equipment from damage. However, if the discharge goes somewhere close and has high energy, no protection will survive. It is also worth having them.
The discussion centers around recommendations for surge protectors suitable for TVs and gaming consoles. The R-20F model by ELGOTECH is frequently mentioned as a cost-effective option, priced around PLN 17, and noted for its dual varistors and spark gaps, which enhance its protective capabilities. Users express concerns about the adequacy of cheaper models and suggest considering higher-end brands like APC and Belkin for better protection. The Belkin F9A402ep2M is highlighted for its features, including EMI/RFI filtering and thermal fuses. The conversation also touches on the importance of not connecting extension cords to surge protectors, as this can compromise safety. Overall, the consensus is that while budget options exist, investing in quality surge protectors is crucial for safeguarding electronic devices. Summary generated by the language model.
