Operation of electrical appliances andequipment is inextricably linked with the function of the local network. The technique works by continually supplying energy and turning off sharply at the time when the current is cut off. Such phenomena can provoke the failure of the filling of the device used. This is caused not only by sudden power outages, but also by sudden voltage drops. In turn, the uninterruptible power supply for the house allows to minimize such risks, completely controlling the energy supply of the serviced equipment.
Before acquaintance with the characteristics of a particularThe UPS model should determine which requirements they must meet. For example, you can focus on the time to support the regime of energy supply, which on average is 10-20 minutes. An even more reliable parameter for assessing equipment compliance purposes is the power of an uninterruptible power supply, which varies on average from 1500 to 2000 VA, although there are deviations from this range. Here it is important to take into account the maximum power potential, which will cover the machinery in operation. This can be one unit and several, but in both cases it is important to add 20% to the power consumed by the device in order to obtain the minimum potential that an uninterruptible power supply must have.
Most likely, it should be high-powerAn aggregate that can simultaneously serve several consumers. If it is a residential house, then probably it uses a computer, and climate technology, as well as kitchen appliances, etc. Combining the total capacity, you can get a value of more than 20 000 VA. In addition, with a greater probability in the list of serviced equipment will be devices with a sensitive to energy differences technical basis. Therefore, it is important that the time for which the uninterruptible power supply for the home resumes energy supply is minimal. On average, this interval takes from 1 to 10 milliseconds, although aggregates with two converters start their function instantly. A suitable option for such needs can be equipment from the line of Power-Vision in the modification of PW3F40. The disadvantage of this model is the large dimensions, but the capacity of 40,000 VA will allow to use practically all the equipment of a typical apartment house.
Obviously, the power requirements in thisthe case is not so high, and the main direction of choice will be addressed to the possibilities of autonomous and independent work. The fact is that during the absence of the host at the dacha, it may be necessary to take into account the parameters of the network operation even without an emphasis on power supply of the equipment. To cope with this task will help Uninterruptible Power Supply Smart from the APC C1500 series. These models do not differ in high power potentials, but are optimal for working in technical rooms, server rooms and in the country.
The user can also configure the functionunit for independent maintenance of some devices taking into account external conditions. If necessary, uninterruptible power supplies Smart can be adjusted to the operating settings via the remote communication channels.
In this case, the UPS will serve oneconsumer or, in extreme cases, a set of devices that form a heating infrastructure. In any case, for such needs, there is usually enough power in 2000 VA. Much more important is the protection of the power supply itself, especially when it comes to working in a unified system with gas equipment. Also consider the strength of the case. It should be metal and, if possible, have small dimensions, although this depends on the area of the boiler room. What else should be the uninterruptible power supply for heating in a private house? It is desirable that the operator should be able to continuously monitor the operating parameters of the equipment, including voltage, overload, battery charge, etc. And it is more cautious to choose models with active cooling systems. To supplement these UPSs, some boilers are subject to severe restrictions.
The spread of prices in the segment is very large, which is understandable,Taking into account the variety of equipment characteristics. Thus, entry-level models designed to serve one low-power consumer may cost around 10-15 thousand rubles. Then follows the average power and universal uninterruptible power supply, the price of which is in the range of 30-40 thousand. Such units are just suitable for servicing separate rooms with critical equipment, boiler rooms, cottages, etc.
The most expensive UPS represents a class of high-powerMultifunctional aggregates designed to serve several consumers simultaneously. This is already an expensive source of uninterruptible power supply, the price of which is about 700-800 thousand. This equipment is also presented in the Power-Vision line.
At first glance, power sources of this typeseem to be very responsible, technologically complex and even dangerous equipment. Of course, it is impossible to underestimate the tasks that such units perform. Moreover, the source of uninterrupted power supply for the house can be interfaced practically with the entire electrical infrastructure. Therefore, it is not only the responsibility of the power supply function, but also the safety of the house as a whole. It's another matter that manufacturers strive to make the operation of the UPS as easy as possible, and also to expand the possibilities for programmable control. As a result, users of modern models spend a minimum of time adjusting the system of equipment, while at the same time getting reliable protection of household appliances of all kinds.
