The Online UPS are extensively used as major power back up source in the following segments:
| Corporate Offices and Call Centers | Banks & ATMs |
| Defense & Para Military Operations | Network Servers, Hubs, Routers and Storage Devices |
| Aviation and Broadcasting | Satellite & Communication Systems |
| Life Saving Medical Equipment & Diagnostic Labs | Photography & Color Labs |
| Vital Real Time & Process Control Equipment |
Unfiltered electrical power supplied by utilities may contain harmonic sags, spikes or other noise. Introducing one or more UPS systems along the power supply chain will effectively eliminate these kinds of disturbances. Most importantly during power failure conditions, the UPS will bridge the critical power supply gap.

| Fault | Remedies | |
|---|---|---|
| 1) | Output voltage Unbalanced |
1. Check input supply weather all 3 phases are present. If so ; 2. Carbon brush may have worn out broken. 3.Snapped or loose; connection on input/output. Correct the same. |
| 2) | Output voltage Fluctuating Continuously |
i) Adjust P3 plot clockwise on the servo control card till fluctuation stop. This can be done only on auto mode. ii)The carbon may be worn out and is causing sparkling on the track. Change the carbon. iii)Check for any loose connection on the input or the output side. |
| 3) | Continuous Rattling/hunting Sound |
i) Adjust P3 plot clockwise on the servo controlled card. Keep switching in ‘auto’ mode. ii) The gear on the motor and the main gear mismatching. Adjust the motor by loosening it four holding screws and moving the motor to match the two gears. Tighten the motor in the correct position. |
| 4) | Output voltage not Regulating |
i) Put the switch in manual mode and try to raise or lower the output voltage. ii) Check if the motor is running. Incase no change in voltage occurs; the gear on the motor shaft is definitely not matching with the main gear. Please do the needful as explained above. iii) Put the switch in auto mode after correction. If still not regulating to the correct value the control card may be defective. Before removing the control card short terminal No. 5 & 6 and then check. If still no function in output voltage occurs , change the card. iv) The voltage adjust pot provided on the front panel may be open, change the pot. |
| 5) | Tank over – heating Beyond limits |
i) Check for overloading on all three phases. The normal temperature of the oil should not be more than 45 degrees centigrade above the ambient. If the temperature is more there may be some short in the winding. Thus, requiring a major repair. ii) The oil might have fallen due to some leakage and this can also result in overheating. |
