About your UPS
An UPS (Uninterruptible Power Supply) is basically a high-tech filter
between the local power company and your electronic equipment. Normally
in the USA, the power companies provide dependable service. But power
outages still occur. If you work regularly with computers, you’ve probably
experienced several occasions when the “lights went out” while you were
working (or playing) on your computer. Perhaps you’ve even lost hours of
work because you forgot to “save” your files. Other forms of power distur-
bances include spikes & surges, frequently occurring during thunderstorms,
that can blow fuses and even destroy equipment. A properly designed UPS
can filter most of such power problems and provide clean, uninterrupted
(hence the name) power to protect your valuable equipment and data.
Features of your TSi Power UPS
• TSi Power’s UPS-550B & UPS-720B series perform the basic function
explained above, and much more. Its architecture is that of a standby UPS
(or off-line UPS), whose inverter is only activated when the line AC becomes
irregular. This has the advantage of lower cost and greater reliability, since
the electronic components don’t have to work all the time. The traditional
disadvantage of off-line UPSs, longer switchover time, has been virtually
eliminated by advanced detection and transfer electronics that reduce the
switchover time to 4 to 8 ms.
• The UPS-550B & UPS-720B can communicate with most popular
network OS’s such as Novell NetWare, UNIX, AppleShare and Windows
3.11/95/NT to provide power protection and automatic shutdown to
network users.
• The UPS-550B & UPS-720B also have remote dial-up capability, which
lets you power up your computer or other equipment via the phone or
modem at any time from anywhere.
