I. INTRODUCTION / PENDAHULUAN
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
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.

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
listrik masukan dan menyalurkannya pada
keluaran UPS, pada saat yang sama baterai
diisi oleh pengisi baterai. Manakala terjadi
gangguan listrik (padam, tegangan terlalu
rendah/tinggi), inverter seketika bekerja
dengan waktu alih
listrik pada beban tidak terganggu/terputus.
Dan bila listrik jala-jala pulih maka
otomatis beban mendapat daya listrik jala-
jala kembali.
