      Definition and Classification of Shante UPS Uninterruptible Power Supply Industr

      UPS Uninterruptible Power Supply Industry Definition
      UPS (Uninterruptible Power System/Uninterruptible Power Supply), which is an uninterruptible power supply, connects batteries (mostly lead-acid maintenance-free batteries) to the mainframe, and converts DC power into market power through module circuits such as host inverters. Mainly used to provide a stable and uninterrupted power supply for a single computer, computer network system or other power electronic devices such as solenoid valves, pressure transmitters, etc. When the city power input is normal, UPS will supply the city power to the load after stabilizing the voltage. At this time, UPS is an AC city power regulator, and it also charges the batteries in the machine. When the city power interruption (accident power outage), UPS will immediately supply the DC power of the battery to the load through zero-switching inverters to continue to supply 220V AC. Make the load work normally and protect the software and hardware of the load from damage. UPS devices usually provide protection against high or low voltage.
      UPS Uninterruptible Power Supply Industry Classification
      UPS can be divided into three categories according to its working principle: backup type, online type and online interactive type.
      Among them, the backup UPS is the most commonly used one. It has the most basic and important functions of UPS, such as automatic voltage stabilization, power-off protection, etc. Although it generally has about 10 ms conversion time, it is widely used in the fields of micro-computer, peripherals, POS machine, etc. because of its simple structure, low price and high reliability.
      Backup UPS power supply is divided into backup sine wave output UPS power supply and backup square wave output UPS power supply.
      Back-up sine wave output UPS power supply: single output can achieve 0.25KW~2KW, when the city power changes between 170V~264V, provide users with voltage regulator-processed city power; when the city power exceeds the range of 170V~264V, UPS provides high-quality sine wave power supply.
      Backup Square Wave Output UPS Power Supply: Unlike backup Sine Wave Output UPS Power Supply, it only provides 50 Hz Square Wave Power Supply for users.
      Online UPS has complex structure, but perfect performance, and can solve all power supply problems, such as four-way PS series. Its remarkable feature is that it can continuously output pure sinusoidal AC without interruption, and can solve all power supply problems such as peak, surge, frequency drift, etc. Because of the need for large investment, it is usually used in key equipment. With the network center and other rigorous power requirements in the environment.
      Online interactive UPS, compared with backup UPS, has filtering function, strong anti-market power* ability, conversion time is less than 4 ms, inverters output to analog sinusoidal wave, so it can be equipped with servers, routers and other network equipment, or used in areas with poor power environment.
