For the smooth operation of electrical equipment, special devices are used, which are called UPS. 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 a computer?
For a computer, it is more expedient to select a block with a wired triode. On average, the limiting frequency should be 60 Hz. If we consider low power devices, then the deviation indicator should not exceed 10 V. Some modifications are available with displays. Thus, the user is able to monitor the operation of the blocks.
The overload indicator for batteries is on average 15 A. Modern modifications are equipped with high-quality overheat protection systems. To connect the batteries, the kit must containnetwork cable. An average device for a computer costs around 25 thousand rubles.
Choosing a device for the boiler
For boilers, a unit with a power of at least 10 kW should be selected. The limiting frequency of the device must be 70 Hz. It is also important to pay attention to the security system. If we consider modifications with two batteries, then they have a fuse. A standard overheating 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.
