The use of a UPS allows you to provide consumers with a continuous power supply without breaking the sine wave. This equipment is necessary for objects that are sensitive to the disappearance or poor quality of power supply in the form of voltage instability. These include:
  • data processing centers;
  • medical institutions;
  • server rooms;
  • heat and water supply facilities (gas boilers, circulation pumps).

It is especially important to use a UPS in situations where there is no backup generator or the ability to install it.


UPSs are designed not only to perform a graceful shutdown procedure, but also to operate in continuous autonomy.

Currently, the UPS installation has a steady upward trend. The practice of our company shows that most often new or modernized production facilities are equipped with these systems, houses with an “Intelligent Management System” (Building Management and Security) or objects that are faced with power supply problems and want to protect expensive elements.


Our company offers a wide range of uninterruptible power supplies (UPS): from ready-made solutions that you will find in our offer or when designing uninterruptible power supply systems for your needs. We have been an authorized supplier of the UPS market leader Schneider Electric since 2007 and we guarantee the quality of the equipment.
We offer the following set of ready-made solutions:
  • household UPS for local workplaces;
  • household UPS of increased capacity;
  • sophisticated UPSs with the ability to expand the battery modules;
  • UPS for mounting in 19 '' server racks;
  • additional battery modules for system expansion;
  • rack-mountable 3-phase systems for data processing centers (DPC).


Our company implements projects for uninterrupted power supply of both simple and complex systems, taking into account:

  • the possibility of expanding batteries;
  • the ability to quickly enter / remove batteries from operation and transfer the system to the "bypass" mode of operation;
  • structures of large dimensions and weight.




For the most correct choice of equipment, it is necessary to understand what tasks it should solve. In accordance with this, all types of uninterruptible power supplies are designed to perform a set of the following basic functions:

  • protection against small and short interruptions in the main power supply network;
  • filtration of arising impulse disturbances and reduction of "noise";
  • backup power supply for a specified period of autonomous operation;
  • short circuit and overload protection.
More complex models have a set of additional functions:
  • automatic deactivation of the protected equipment in case of longer critical power outages, as well as restart when the required parameters are restored;
  • monitoring of the main parameters of the source functioning, tracking the level of its operability;
  • display of basic information about the operating UPS, as well as the parameters of the input voltage of the mains supply;
  • automatic alarm in the event of abnormal UPS or load modes;
  • the presence of an installed timer for configurable switching off or switching on of the consumer at a set time.

Types variety

There are 3 main types:

It is widely used in combination with home or office computers or low-power LAN workstations. It is also effective in terms of protecting household appliances that do not require a special quality of power supply, allows power outages for a certain time and the occurrence of deviations from the input voltage parameters on average +/- 5%.
It can act as a backup. However, its main tasks are broader: in addition, it performs step voltage stabilization, which makes it possible to use it in electrical devices with increased inrush currents. This is any device or other equipment that uses an electric motor, the start of which requires increased power for a short time. In particular, the operation of the compressor of the refrigerator (refrigeration unit) in conditions of deviation from the normal voltage parameters can lead to its overload and failure. However, the efficiency of these protective devices is slightly lower than the same parameter for the backup ones.
Provides the most effective protection and is now widely used. Operation on the principle of double conversion (on-line) provides rectification of the input voltage and, with the help of an inverter, converts it into alternating voltage. Relevant for file servers and more complex workstations. It is used in combination with equipment for financial institutions, medical clinics and research scientific centers. That is, almost everywhere, where absolutely high-quality power supply is needed with the absence of even short-term voltage dips. In everyday life, such devices are ineffective (high cost at low loads) and are distinguished by increased noise and impressive heat release.
Application by current type:
  • Online or double conversion uninterruptible power supply. Such uninterruptible power supplies are necessary to ensure the protection of electrical devices that are connected to a network with a voltage of 24 V, 48 V and 60 V.
  • AC UPS. Uninterruptible power supplies of this type are used in combination with the most important consumers who require a voltage of 220 or 380V 50Hz.

Power application
UPSs are divided into three groups according to their capacity:

  • low-power;
  • medium power devices;
  • high power modular systems.

They are widely used for domestic purposes, as well as to protect individual consumers from possible critical situations in offices or small industries.


Medium power
Responsible for high-quality and uninterrupted power supply of local networks, data centers and various telecommunication equipment, as well as means of remote communication.


High power
Differs in several advantages at once in use. It is able to provide protection for both an individual residential cottage and a large production process. In addition, such a UPS is a kind of modular system that allows you to synchronize several sources in one 19 “rack to obtain higher power values when solving specific technological problems.
