When Utility is normal, the AC source is rectified to DC, which fed into the inverter.
The charger will turn on automatically to charge batteries. The inverter revert the
DC to a cleaned and pure AC to supply energy to the load connected. The
,
,
LEDs illuminated.
Fig 5.2
5.3. When Utility is Abnormal/Absent
The working principle of the UPS under Utility abnormal condition is illustrated
as follows:
1. When Utility is abnormal, the UPS will direct the battery energy automatically to
the Inverter without delay, and turn off the charger and AC/DC converter. The
inverter revert DC to AC to supply energy to the output load connected without
interruption. The
LED will be illuminated.
2. When Utility is back to Normal, the UPS will turn on the AC/DC converter, turn
off DC/DC converter and switch the charger to charging mode. It has the same
working principle as figure 5.2.
3. During a utility outage, the UPS will work as illustrated in figure 5.2. When
Battery is low, buzzer will beep continuously till battery is completely cut off.
The battery low protection of the UPS will cut off battery supply after a preset
threshold to avoid the battery from over-drain. The
&
(Battery Low)
LEDs will light up till the UPS is completely cut off. The UPS will re-start
automatically when Utility is available.
Fig 5.3

5.4. Overload Condition
The working principle of the UPS when overloading is illustrated as follows:
1. Generally modern day electronics & IT equipment generate an inrush current
when switching on. The amount of inrush current varies from equipment to
equipment, some can be as high as 6 times its rated capacity while others
produce negligible inrush. To prevent severe damage to its Inverter cause by
the inrush produce by the loads, the UPS is equipped with electronics overload
protection feature as standard. If the UPS loading is >105~120% of its capacity,
it will switch to bypass mode in 30 seconds to protect the Inverter. If overload
condition is eliminated by reducing the load to <105%, the UPS will switch back
to Inverter mode automatically. If the UPS is over 150% loading, it inverter will
shutdown immediately.
Fig 5.4
2. The UPS Bypass loop is also equipped with overload protection. Its overload
capacity is illustrated by the graph & table below.
5.5. Inverter Failure
Output Load short circuit when supply via inverter
If output load is short circuited while supply via Inverter, the UPS will shutdown
Inverter automatically and stop supply to the loads. The Fault LED lights up
and the buzzer will beep continuously. The UPS will not switch on
automatically after short circuit condition is eliminated. The UPS has to be re-
start manually (refer to 4.5.1 ‘Start Up in Normal AC Mode’).
41
5.6. Inverter/Internal Over temperature
If the UPS experiences internal over-temperature when Utility is normal, it will
switch to bypass loop. The UPS will switch back to inverter mode when the
over-temperature situation is eliminated. If over temperature occurs when
Utility is abnormal, the buzzer will beep continuously and the Fault LED
will light up. The UPS will cut off supply to the loads.
5.7. Inverter Over
-current and Inverter Output Voltage Out of tolerance
If the UPS inverter delivers over-current and out-of-tolerance voltage to its
outlets, the UPS is out of order. The UPS will switch to bypass loop when
Utility is normal. The Utility
LED, Bypass
LED and Fault
LED will
light up.
If these two fault conditions occur when Utility is abnormal, the UPS will cut
off the supply to its outlets and the Fault
LED will light up.
6.1. Trouble Shooting
