UPS定义 UPS是英文UninterruptablePower System的缩写,中文译为不间断电源。UPS是伴随着计算机的诞生而出现的,它含有储能装置,以逆变器为主要元件,稳压稳频输出的电源保护负载。当市电正常输入时,UPS就将市电稳压后供给负载使用,同时对机内电池充电,把能量储存在电池中;当市电中断或电压不正常时,UPS立即将机内电池的能量转换为220V交流电继续供负载使用,使负载维持正常工作并保护负载的软、硬件不受损坏。目前UPS的使用已经广泛的应用于计算机、交通、银行、证券、通信、医疗、工业控制等,而且正逐步的走进家庭。
UPS definition UPS is English abbreviation UninterruptablePower System, Chinese translated as uninterruptible power supply. UPS is accompanied by the birth of the computer appeared, it contains energy storage devices, the inverter as the main component, the power supply to stabilize the output voltage to protect the load. When the mains is normally input, the UPS supplies the load with the mains voltage, and charges the battery in the machine to store the energy in the battery. When the mains is interrupted or the voltage is not normal, the UPS immediately switches the battery 220V AC power conversion to continue to use the load, the load to maintain normal work and protect the load of the software and hardware are not damaged. The current use of UPS has been widely used in computers, transportation, banking, securities, communications, medical, industrial control, etc., and is gradually into the family.
