Shenzhen UPS Uninterruptible Power Supply, Shenzhen UPS Uninterruptible Power Supply Manufacturer, Shenzhen UPS Uninterruptible Power Supply Price [Shenzhen Nuonai Power Supply] The UPS Uninterruptible Power Supply is now widely used in: mining, aerospace, industry, communication, defense, computer business terminals, network servers, network equipment, data storage equipment UPS, emergency lighting systems, railways, shipping, traffic, power plants, substation, nuclear power plants, fire safety alarm systems, wireless communication systems, programmable switches, mobile communication, solar energy storage energy conversion equipment, control equipment and their emergency protection systems, personal computers. UPS is divided into three main categories according to the working principle: backup, online, and online interactive. Among them, the most commonly used is the backup UPS, which has the most basic and important functions of UPS such as automatic voltage regulation and power outage protection. Although it usually has a switching time of about 10ms, the inverter output AC is a square wave instead of a sine wave, it is widely used in microcomputers, peripherals, and other fields due to its simple structure, low price, and high reliability. The online UPS has a more complex structure but perfect performance, can solve all power problems, and its significant feature is that it can continuously output pure sine wave AC without interruption, solving all power problems such as spikes, surges, and frequency drift. Due to the larger investment required, it is usually used in critical equipment and network centers, etc., where strict power requirements are placed. The online interactive UPS, compared with the backup UPS, has filtering function, strong anti-power interference capability, a switching time less than 4ms, and inverter output as an analog sine wave, so it can be equipped with server, router, and other network equipment, or used in areas with relatively harsh power environments.
