I. INTRODUCTION / PENDAHULUAN
UPS (Uninterruptible Power Supplies) can
provide full protection against all of power problem
for
your
sensitive
equipment
computer,
computerized
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
power fails (off, voltage too low/high), 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.
Computer is power fail and battery low.

UPS (Uninterruptible Power Supplies) dapat
melindungi peralatan Anda yang rentan terhadap
gangguan kelistrikan seperti: komputer, instrument
terkomputerisasi, PABX, faksimili, cash register
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
menyalurkannya pada keluaran UPS, pada saat yang
sama baterai diiisi oleh pengisi baterai. Manakala
terjadi gangguan listrik (padam, tegangan terlalu
rendah/tinggi), inverter seketika bekerja dengan
waktu alih
<
4 ms sehingga pasokan listrik pada
beban tidak terganggu/terputus. Dan bila listrik jala-
jala pulih maka otomatis beban mendapat daya
listrik jala-jala kembali.
UPS
ini
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.
