I've had bad experiences with MOV based surge protectors, not just from a specific brand but from a person. Потеряв оборудование на тысячи долларов, я, наконец, поумнел и исследовал различные технологии, включая двойное преобразование (переменный ток->постоянный ток, постоянный ток->переменный ток) и изолирующие трансформаторы, оба из которых непомерно дороги в одном приложении (по крайней мере , to me). a whole house. I got rid of MOV protection as the technology is no different among the hundreds of models available. Even some companies' supposedly "high-end" models, where surge protectors can cost hundreds of dollars, are still based on MOV technology. Manufacturers have gone to great lengths to protect the MOV (and hopefully your gear) by offering technologies such as the ceramic case of the MOV and putting a fuse inside the MOV so that when it eventually wears out, the MOV will either be disabled. Circuit or turns off the power for protection and, accordingly, everything connected to it. It's up to you to decide which one to use (e.g. you may want the electronics to continue working if the CPAP machine surge protection or safety system is lost). The difficult question will be what modern refrigerators with built-in computers do. No one knows when the MOV surge protector will finally die and if there was a sensor (like a battery charge sensor which would have been invented by now). If you are here then you have done your research and decided to buy a Sequential Mode Power Filter as it works completely different than the MOV based solution, non-sacrificing and just works. In all likelihood, he will outlive our lives and the lives of our children (it's that good). I don't work in the electronics industry or any surge protection company. I'm a retired engineer who just wants to help my fellow Revain buyers. I love products that work and dislike products that don't work or are harmful. This is an opinion, not a prejudice.
