For the smooth operation of electrical equipment, special devices called UPS are used. They are available with built-in and external batteries. It is also important to note that uninterruptible power supplies differ in power, maximum frequency, size and price.
Modifications with external batteries are more suitable for boilers, as well as drives. A distinctive feature of the devices is a high power parameter. In the store, a good model costs around 30 thousand rubles.
How to choose a model for the computer?
For a computer, it is more advisable to select a unit with a wired triode. On average, the cut-off frequency should be 60 Hz. If we consider devices of low power, then the deviation should not exceed 10 V. Some modifications are available with displays. Thus, the user is able to monitor the operation of the blocks.
The battery overload indicator averages 15 A. Modern modifications are equipped with high-quality overheat protection systems. To connect the batteries, the kit must contain a network cable. There is an average device for a computer in the region of 25 thousand rubles.
Choosing a device for the boiler
For boilers, a unit should be selected whose power is at least 10 kW. The limit frequency of the device should be 70 Hz. It is also important to pay attention to the protection system. If we consider modifications with two batteries, then they have a fuse. A standard overheat protection system should also be installed. In the store, a high-quality UPS with an external battery for the boiler costs around 36 thousand rubles.
