Many users do not use network filters for the computer just because they do not know why they are needed. And, among other things, the presence of this device is highly desirable for the normal operation of each computer. It can prolong its service life, protect it from failure and help the user save unsaved documents from destruction at power surges. Still in doubt, do you need a surge protector?
Principles of the filter
The purpose of the network filter is to suppress the voltage fluctuations in the electrical network at the output where the device is connected. This device serves as a protective barrier for the devices included in it, it reduces to a minimum the chance of device failure at the next power surge in the network. At the heart of the filter are two blocks: the first stabilizes the voltage, and the second voltage. These elements are equalized at the moment of the voltage jump, and if the voltage is higher than their limiting power, they burn out, thereby protecting the device included in them. If your computer is equipped with a mains filter with protection (fuse), then when the voltage drops above the permissible limit, the cut-off is triggered, as in semiautomatic machines. From the next section you can understand which network filter is considered the best computer for experts.
Usually, the network filters look very much like the most common extension cable. Outwardly, they can differ substantially, but with their "duties" will equally well handle both the cheapest and the most expensive. The difference is only in their service life, the quality of the unit with outlets, where household appliances are plugged into the forks, as well as the presence of a fuse or cut-off. This determines whether the filter will be reusable or will burn at the first serious voltage jump. Very nice and the presence of some small things, like an LCD, displaying the current voltage in the network and the status of the device. We hope that you understand what a network filter is for, and you have found it necessary. Now it remains only to give some recommendations regarding the choice of a suitable model, so let's proceed.
Features of network filter selection
Filter filter - discord. Not paying attention in time to some nuances, you risk acquiring a short-lived, substandard, and, finally, just an uncomfortable device, the work with which will only irritate. So how to choose the right power filter so that it can protect your devices, lasted long, and its operation was simple and convenient?
- First of all, make sure that there is protection on the filter, otherwise it will become useless after the first serious jump.
- The network cable of this device must be of a certain length (not too long, and not very short). It is better to choose a computer with a choice of six or more sockets.
- The box with rosettes should be compact, to what to buy a hulk, after all the XXI century on a court yard!
- Make sure that the device has enough power to work without overloading with all the devices included in it.
As you already understood, the network filter is a very useful thing. In particular, it is able to almost double the resource of the PC power supply and, importantly, from the power surges, it will stop rebooting. This situation is certainly familiar to everyone - the light blinked, and the PC rebooted, destroying the fruits, perhaps, of hours of work. To protect yourself from such incidents, you need a network filter.
