0ff-line UPS:

I
n this system, the load is normally on Mains power supply. This may be regulated to some extent by an in-built voltage regulator. When the Mains power fails, the inverter takes over and supplies power to the load while draining the battery. This is a cheap system for countering the power failure problem. However, it is not advisable to use this at places where voltage fluctuation is severe and in areas where large power consuming machinery is being used. This machinery, while being switched ON & OFF, causes high-energy spikes, which can damage sensitive equipment permanently.

On-line UPS:

This perhaps is the only complete answer to power line problems. In this system, the load is always connected to the inverter. This inverter works either on rectified Mains voltage in case of the Mains power being available, or works on battery in case of Mains failure. The rectified Mains and battery being connected in parallel. This system is a true No-Break power supply. Load being always on inverter, it is totally isolated from all the power problems like fluctuations, brownouts, spikes, frequency drifts, noise etc. Thus this system is the most advisable in the areas where clean power is important.

In the light of above, need of the sensitive equipment, problems related to the area, future planning like expansions and naturally the budget will decide upon the power conditioning equipment to be chosen. This is precisely the field where a saving today might prove expensive tomorrow .
