I. INTRODUCTION /
UPS (Uninterruptible Power Supplies) can provide full
protection against all of power problem for your sensitive
equipment ranging from computer, computerized instrument,
PABX, facsimile, cash register to all electronic equipment.
This UPS consists of inverter, batteries, battery charger,
control circuit, stabilizer, transfer switch and indicator. When
line power is normal, the UPS filters line power input and by
pass to output UPS and at the same time the batteries is being
charged by battery charger. And when line p ower fails (off,
voltage too low), inverter will supply regulated AC power to
the load within < 4 ms transfer time so that the power
supplied to the load is uninterrupted. And when line power is
normal automatically load gets from line power again.
This UPS is also completed by interface for
communication with computer, with operating system
Windows 95, 98, ME, Unix / Linux and Windows NT4/2000.
Information from UPS to Computer is power fail and battery
low.

UPS (Uninterruptible Power Supplies) dapat melindungi
peralatan Anda yang rentan terhadap gangguan kelistrikan seperti:
komputer, instrument terkomputerisasi,
dan peralatan elektronik lainnya.
UPS ini terdiri atas inverter, baterai, pengisi baterai, rangkaian
pengendali, stabilisator, saklar-pengalih dan indikator. Saat listrik
jala-jala normal, UPS menyaring listrik masukan dan menyalurkannya
pada keluaran UPS, pada saat yang sama baterai diiisi oleh pengisi
baterai. Manakala terjadi gangguan listrik (padam, tegangan terlalu
rendah), inverter seketika bekerja dengan waktu alih
pasokan listrik pada beban tidak terganggu/terputus. Dan bila listrik
jala-jala pulih maka otomatis beban mendapat daya listrik jala-jala
kembali.
UPS ini dilengkapi interface untuk berkomunikasi dengan
komputer, dengan sistem operasi Windows 95, 98, ME, Unix/Linux
maupun Windows NT4/2000. Informasi yang diberikan kepada
komputer adalah listrik padam dan baterai hampir habis.
