UPS for Medium Voltage Distribution UPS 8000H
solutions for voltage sags and energy saving inmedium-voltage distribution power supply
Large Capacity Uninterruptible Power Supply Systems for M.V.
voltage sags and momentary interruptions have always existed in power systems. in the past, low-voltage ups and other various methods had been implemented against interruptions and sags.
in recent years, however in industrial field, production equipments are becoming very sensitive and occurrence of the interruptions and sags are becoming unacceptable.
亚博软件上赌博是怎么回事but in terms of cost effectiveness and complicated machinery maintenance, it is difficult to implement a reliable device in individual equipments.
亚博软件上赌博是怎么回事in order to meet the market needs, as a sag protection, fuji electric has commercialized the ups8000h series (large capacity uninterruptible power supply systems for 3.3kv, 6.6kv circuit) using lithium ion capacitor as energy storage device. ups8000h series were successfully supplied to manufacturers having sensitive equipments, such as customers in semiconductor industries, precision machined industries, and internet data centers.
亚博软件上赌博是怎么回事ups8000h series supplies power from distribution substation to the load through semiconductor switch and charges electricity in energy storage device at the same time. when detecting the voltage sags or momentary interruptions, semiconductor switch will break the main circuit in high-speed and converter unit will begin discharging from energy storage to the load without any interruptions.
