Uninterruptible power supply (UPS) - a secondary power source, which is used in cases of main power failure. It is designed for short-term use (from half an hour to several hours, depending on the power). In addition, the UPS allows you to protect household appliances and other devices and devices operating from the power grid, from power surges, as it is known because of excessive high voltage in the network often breakdown electrical equipment in the home, office or enterprise.

In simpler terms, the UPS is a spare battery pack that for some time conserves the energy level consumed by an electrical appliance.

Types of UPS The UPS of various brands and capacities. In particular, the LogicPower uninterruptible power supply units, which are distinguished by reliability, high quality and reasonable price. You can choose the LogicPower UPS you need:.

On sale, mainly linear-interactive UPS models exist, which can be of two types: with an approximated or with a correct sinusoid. The first are ideal for connecting computers and any other office equipment. The latter are considered universal, that's why they are recommended by specialists for connecting to TVs, refrigerators and other household appliances.

Rules for choosing a UPS In order to choose the optimal UPS model, it is worthwhile to know the total power of electrical appliances that you are going to connect to it. In addition, it is worth choosing the location of the battery - inside the device or outside. The internal layout predisposes the parsing of the power supply and the extraction of the battery for recharging, while the external arrangement allows the UPS to be recharged without having to disassemble it.

It is also worth taking into account the battery life of the device with the maximum power consumption.

Thus, to connect to computers, it is better to give priority to a high-power UPS, since the device must withstand the maximum loads until you can save data on your computer and turn it off. As for the power of the UPS that you want to connect to a refrigerator or a TV, then devices of minimum or medium power are suitable, since their main task is to reduce to zero the risks of sudden voltage fluctuations in the network, and they should not prolong the work of household appliances for a long time.
