Summary: A single utility source is normally how each of us manages on a daily requirement for energy. Beware of this, as this lone supplier may feel overloaded at times and decide to cut off its' energy supply. It is in such a situation that we need an UPS to provide us with an uninterrupted power supply.How do we know which one to choose and which one is good?
As is known, uninterruptible power supplies or UPS are a back up source of energy that provide emergency power to devices that are connected to it until the main utility source is restored or the equipment safely switched off. Places such as hospitals rely on an uninterrupted power supply to save lives. It deters serious situations by keeping the power supply on all the time.
But how can we tell which uninterruptible power supply is appropriate for us. There are two primary kinds of uninterruptible power supplies, the on-line and the line interactive UPS systems. The on-line uninterruptible power supply utilises the ‘double conversion’ technology wherein it takes in the AC input that is available from the main utility source and converts it into DC power, which is required for it to pass through the battery and again changes it back to AC power to run the connected equipment.
The line interactive uninterruptible power supplies have an internal or in-line inverter that transmits the DC power of the battery from the standard charging form to supplying energy during an emergency power failure. It is analogous to the stand by or off-line UPS except for the fact that it has a flexible electrical transformer that has the ability to increase or decrease the magnetic field and the produced voltage of the transformer. This has the ability to suffer Low voltage brownouts and high voltage surges without using up any stored energy.
An on-line UPS is perfect for situations where there are extreme voltage fluctuations and the equipment connected to it is highly sensitive. They are more expensive than the line-interactive and the stand by UPS and were earlier available only for larger consumption installations. They are available now however, in smaller consumer equipments. These use about 500 watts of power. Areas that use large noise making equipment tend to use these as the location is convenient. Apart from this they may require a back up generator to supply an uninterrupted power supply to these equipments.
This powerful UPS system is more advanced and more expensive than the other two UPS systems due to the fact it has an advanced cooling system that efficiently provides energy sources to your equipment and a powerful AC to DC converter. No power transmission switches are required on this on-line UPS system as the converter moves out of the circuit when there is a power cut and then when it is connected back to the main power supply it will resume charging.
You can decide which uninterruptible power supply system is best for you based on the two designs and functions. Uninterruptible power supply will always provide you uninterrupted power no matter what your situatiion; this is regardless as to whether this is for home, office or a large organisation.
