What are the features of the UPS uninterruptible power supply?
The main features of UPS power supply include over current alarm, over voltage protection, short circuit protection, overload protection and short circuit alarm. Some of the UPS is now intelligent, in power (level discipline), power planning, design and construction (two disciplines), hospitals, banks, securities and other departments. When the power input is normal, UPS electric voltage supplied to the load, the UPS is an AC power regulator, it is also the built-in battery; when the power interruption (outage), UPS will immediately machine battery power through the inverter conversion method continue to supply 220V AC power to the load, the load to maintain normal working load and protection of software and hardware are not damaged, that is the work of the normal operation of equipment; is processing the data is not lost.
UPS is the abbreviation of uninterruptible power system, which is an important external equipment to provide continuous, stable and uninterrupted power supply.In principle, the UPS is a power electronics device incorporating digital and analog circuits, automatic control inverters, and maintenance free storage devices;Functionally, UPS can effectively purify the city power when the city power is abnormal. It can also supply power to the computer and other equipment for a certain period of time when the city power breaks suddenly, so that you can have enough time to cope with it;From the use, with the coming of information society, UPS is widely used in the information collection, transmission, processing, storage and application to each link, its importance is increased with the increasing importance of information applications.
UPS (Uninterruptible, Power, System), that is, uninterruptible power supply, is a kind of energy storage device, inverter as the main component of constant voltage constant frequency uninterruptible power supply. Used primarily to provide uninterrupted power supply to a single computer, computer network system, or other power electronic equipment. When the power input is normal, UPS electric voltage supplied to the load, the UPS is an AC power regulator, it is also the built-in battery; when the power interruption (outage), UPS will immediately machine battery power through the inverter conversion method continue to supply 220V AC power to the load, the load to maintain normal working load and protection of software and hardware is not damaged. UPS devices usually provide protection against too large voltages and too low voltages.
UPS is not only a standby power supply, but also has the functions of voltage regulation, anti-interference, lightning resistance and isolation from the power system. The UPS serves as the power source of the equipment, making the device an independent electrical system, free from external influences.
