http:www.everexceedcorp. Classification of UPS Power Supply What is a UPS?UPS is
an abbreviation of Uninterrupted Power System, in Chinese it is also known as an
uninterruptible power supply system. UPS is the uninterruptible power supply of
constant frequency with one pound containing the energy storage device, the
inverter, a battery pk, such as the major ponent of the constant voltage, when
the mains is normal, UPS electricity regulator or regulator, frequency
stabilization for load, and at the sa ti to charge the battery inside; When
utility power is interrupted (abnormal) UPS 4-10 milliseconds imdiately or the
interruption ti is "zero" of the battery Mike
Nugent Jersey , power supply through the inverter switching to the
load to continue to supply electric power, so that the load can maintain normal
working, in order to save the data and to protect the load from damage of
hardware and sofare. So far, the UPS battery pk in the industry is the lead-id
battery.UPS Rectifier UPS Bkup PowerThe online ups systems can keep the mains
supply when the mains regulator are normal, if the inverter does not work then
it will be in a waiting state. When the City Neork voltage is abnormal, UPS will
quickly switch to the inverter status and continue to supply battery power. So
the inversion to AC of load bkup UPS power supply change into the inverter work,
there will be a period of conversion ti. Generally, it is smaller than 10MS. UPS
serious pollution is on the grid, and anti -interference ability is poor, simple
lines, cheap terminal equipnt to use at the office Reggie
Nelson Bengals Jersey , ho and other less demanding (Separate the
charger and inverter).Online UPS Power SupplyThe inverter is always working, the
online ups systems are always tive in the boot, when the mains is normal, the
UPS charger will charge the battery and convert direct current to alternating
current rather than direct mains supply equipnt; When City mains are abnormal,
the UPS switch to battery-powered electric exception ours when no interrupt
interrupt on the ti that ows "0". At this ti, the UPS power has strong sofare
managent capabilities, suitable for the workstation work equipnt departntal and
local for high requirents.Line-Intertive UPSThe Line-Intertive UPS is both the
Charger and inverter, so it is called double conversion. The online intertive
ans when the input of mains is normal, that is, the power inverter to charge the
battery in reverse, when fluctuations in the mains imdiately into the
inverter Reggie
Nelson Womens Jersey , the power to the battery pk into the AC
output, line intertive UPS power has certain conversion ti, pared with the sa
bk-line intertive protection capability, the inverter output voltage waveform is
better generally sinusoidal. This UPS power has the sofare function, it can
easily hieve remote control and intelligent managent, suitable for servers and
miniputers.www.everexceedcorp. is a leading manufturer professionally
specialized in developnt, design, and manufturing of various UPS products to
