What is an uninterruptible power supply? What are its characteristics?

What is an uninterruptible power supply? An uninterruptible power supply is a device that continuously supplies backup AC power to electrical load equipment and maintains the normal operation of electrical appliances in the event of abnormal power grids (such as power outages, undervoltages, interference or surges, also known as surge currents). It is mainly used to supply a stable and uninterrupted power supply to a single computer, computer network system or other power electronic equipment such as solenoid valves, pressure transmitters, etc. When the mains power is normal, the uninterruptible power supply will supply the load after the mains power is stabilized. At this time, the uninterruptible power supply acts as an AC voltage stabilizer and can also charge the battery in the host to prevent power failure. Electricity problems also protect the normal operation of the load. UPS uninterruptible power supply can solve all power problems, and better supply everyone with electricity needs. It is used more in many fields. It is one of the more functional power supply categories, which can make our life more comfortable. Features of uninterruptible power supply 1. Green, energy-saving, and environmental protection: In the context of intensified changes in the world's energy structure, violent fluctuations in international oil prices, and tight global energy supply, energy conservation and environmental protection have become the guiding principles for UPS manufacturers to innovate their products. For UPS, the level of input power factor indicates its ability to absorb active power from the grid and the degree of influence on the grid. Reducing the input harmonics of the power supply can not only improve the load characteristics of the UPS on the power grid, reduce the serious pollution to the power grid, but also reduce the harmonic interference to other network equipment. Many UPS manufacturers have introduced products with a power factor close to 1, which can minimize the consumption of reactive power. 2. High frequency: Compared with traditional power frequency UPS, high frequency UPS adopts power factor correction and high frequency soft switching technology, eliminating the need for power frequency power conversion, so the operation efficiency is higher, the harmonic pollution to the grid and the The reactive power consumption is extremely small, and it can fully meet the standard requirements of the relevant power industry at home and abroad. In addition, high-frequency power conversion devices have significant effects in reducing the volume and weight of magnetic components, reducing manufacturing costs, curbing operating noise, energy saving and environmental protection, and are therefore more and more recognized by users. 3. High-power and modularization: Due to the rapid development of the IT industry, the amount of data in the data center continues to rise at an explosive rate, and power consumption increases as a result. On the one hand, UPS is developing in the direction of greater power, and on the other hand, in response to the demand for phased expansion of uninterruptible power supply capacity, product modularity has become an unstoppable trend. More personalized user needs, larger data center scale, and higher maintenance costs make UPS no longer a simple uninterrupted power supply equipment, and a complete set of power supply and management solutions for different industries will be favored by the market. .
