I. INTRODUCTION / PENDAHULUAN
The ST Series UPS is an advanced true online sinewave Uninterruptible Power Supplies
with high voltage PWM (Pulse Width
Modulation) technology and static transfer
switch. The UPS can provide reliable, regulated,
transient free AC power to sensitive equipment
ranging from computers and telecommunication
systems to computerized instrument.
The UPS has high non linear load current
capability (crest ratio 3:1) and this is suitable for
powering special loads such switching power
supplies or high capacitive load.
The static transfer switch (STS) system
provides bypass power as its standby source.
Upon inverter failure or overload, the STS will
switch the output power Bypass (if the power line
exists) within 0 ms. The STS can retransfer back
to inverter automatically when the system is
restored to normal condition within 2 ms.
This UPS is also provided 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.

mengalami kegagalan atau mendapat beban lebih,
STS akan mengalihkan sumber daya untuk keluaran
UPS dari inverter kepada daya dari jala-jala/PLN
(apabila daya jala-jala ada) dengan waktu alih 0 ms.
STS otomatis akan kembali mengambil daya dari
inverter dalam waktu 2 ms apabila sistem kembali
ke kondisi normal.

V. START UP UPS / MENGHIDUPKAN UPS
1. Make sure main switch is in the off position and
no load is connected to the UPS output.
2. Connect inlet to the mains. The indicator
“INPUT” will light on.
3. Turn on the main switch, the indicator
“INVERTER” light on and the indicator
“BYPASS” light on for about 20 seconds, and
will go out, at the same time battery level led
will light on (depend on the battery condition)
and the indicator “INVERTER OUTPUT”
will light on.
4. Disconnect inlet from the mains, the indicator
“INPUT” will go out and audible alarm will
sound with 4 seconds intervals. Now the output
is supplied from the battery source.
5. Connect inlet to the mains again. The indicator
“INPUT” will light on again.
6. Now UPS is ready for operation. Plug the
critical devices such as computer, disk drives,
monitor, printer or electronic instrument to the
output UPS.
1. Pastikan posisi Main Switch, pada posisi “OFF”
dan tidak ada beban yang terpasang pada
terminal output UPS.
2. Hubungkan kabel input PLN, indikator
“INPUT” akan menyala.
3. Hidupkan main switch, indikator “INVERTER”
menyala dan indikator “BYPASS” menyala ±
20 detik kemudian akan mati, bersamaan
dengan itu indikator baterai level akan menyala
(tergantung kondisi baterai) dan indikator
“INVERTER OUTPUT” akan menyala.
4. Lepaskan kabel input PLN, indikator “INPUT”
akan mati dan buzzer akan berbunyi setiap 4
detik, berarti UPS bekerja dengan battery
sebagai sumbernya.
5. Hubungkan lagi kabel Input PLN, indikator
“INPUT” akan menyala kembali.
6. Sekarang UPS siap menjalankan fungsinya,
hubungkan peralatan yang sensitif seperti
komputer, diskdrive, monitor, printer atau
iInstrument elektronik lainnya ke unit output
UPS.
VI. OPERATION PROCEDURE / CARA MENGOPERASIKAN

Output.
2. Pada saat tegangan jala-jala mati, UPS akan
segera bekerja tanpa waktu transfer (0 ms) dan
Buzzer akan berbunyi tiap 4 detik. Pada saat
battery akan habis, buzzer akan berbunyi tiap 1
detik.
3. Mematikan UPS :
a. Matikan semua beb a n yang terpasang pada
UPS.
b. Matikan Main switch pada panel depan
