While we all know that our daily requirements depend largely on energy sources provided by a single utility power, we must also be aware of the fact that this lone supplier may get overloaded and cut off its source for some time.
It is in such a situation that we need an UPS to provide us with an
APC battery backup.
How do we know which one to choose and which one is good?
As is known,
APC Battery Backups or UPSs 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 double-conversion is utilized by the on-line uninterruptible power supply. This
means it takes in the AC input that is available from the main utility source and then converts it into DC power.
This is necessary for it to pass through the battery. Once this is done it converts it back to AC power which runs 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. This UPS system is similar to the stand by or off-line UPS system but it has a flexible electrical transformer that has the ability to increase or decrease the magnetic field and therefore produce a different voltage to that of the transformer. It is able to
withstand constant low voltage brownouts and high voltage surges without using up the 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.
However, they are now available in smaller consumer equipment that use about 500watts of power. Areas that use large noise
making equipment tend to use these as the location is convenient. A backup generator, apart from this may be required to supply these equipments with uninterrupted power supply.
They are more expensive than the other two types of UPS systems for the sole reason that they have a powerful AC to DC converter with advanced cooling systems that allow them to efficiently provide energy sources to your equipment.
The on-line UPS require no power transmission switches as the converter moves out of the circuit when there is a power cut and moves back in to resume charging when the main power supply is restored. You can decide, based on the two designs which uninterruptible power supply suits you the best. Uninterrupted power is an essential part of your environment if you want to be hassle free, as whether you are at home, in the office or work for a
large organization it will always provide you with an uninterrupted power supply.
