We live in an era of rapidly developing technologies. Some of them satisfy the basic needs of human life, while others provide its communications, comfort and safety, and others themselves are used as a means of production. And all of these devices operate by the power supply. If we imagine that these devices suddenly stopped working, then surely a person's life easier would not. It is no secret that today ensure power is not always reliable, especially during inclement weather conditions. Hence there must be an effective means to protect equipment from malfunctions in the power supply. That is why in the case of a hurricane or as we are witnessing heavy snowfall, when de-energized left dozens of settlements, uninterruptible power supplies are used.
This is a device whose main function is to protect against sharp changes in voltage sources and maintain proper operation of equipment in the event of termination of its submission. To ensure that emergency power using rechargeable batteries, which are and will continue it. The battery is also used to backup computer systems, fire alarm systems, cctv systems, elektroradioapparatury, communications systems and other devices. Such batteries designed for use as a source of dc ups systems communications companies, telecommunications systems or in other process equipment at the facilities of communication, power and other industries where failures are not allowed or stopped in the technology. They are designed to ensure that no data loss (if the computer), and without prejudice Electronic complete the equipment in case of emergencies.
In the operation of such a battery is quite simple. Speaking candidly Michael Dell told us the story. Technical specifications for the entire life of the battery does not check the electrolyte level and do not add water. Gaza is completely amenable to recombination (99%). Do not allow leakage and spillage of the electrolyte. Sealed battery design allows the batteries to operate in any position (vertical or horizontally, but not completely inverted). Batteries are supplied by the manufacturer in the charged state, the electrolyte-filled and ready for use. Also, batteries do not require additional topping up with distilled water in the electrolyte and are designed to work in its original condition throughout its entire life. They are equipped with safety valves that prevent the penetration of gas (Air) and providing a release of gas in excess of the internal gas pressure in the accumulator above the allowable, which does not cause deformation or other damage to the battery. This device is fully responsible requirements of the explosion and fire, and are designed not only to provide power to devices with a given constant voltage in the absence of mains voltage, but also to protect the electrical equipment at output voltage within the tolerance limits.
