The Different Types Of Uninterruptible Power Supplies On The Market Today
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 sometime. It is in such a situation that we need an UPS to provide us with an uninterrupted power supply.Which one is good for us and how can we tell?
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. Uninterruptible power supplies have two primary kinds; the on-line and the line interactive UPS systems. The double-conversion is utilised 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. 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. 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. The line-interactive and the stand-by UPS are slightly cheaper than this one and were once used only in large consumption installatiions. However, they are now available in smaller consumer equipment that use about 500watts of power. They are convenient for locations where there are large numbers of noise-making equipments such as those seen in large industries. To supply uninterrupted power supply to these equipments it is necessary to have the backup of a generator.
Due to the fact that they have a powerful AC to DC converter and an advanced cooling system, they are more expensive than the other two types of UPS systems. They do however, provide efficient energy sources to your equipment. 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.
Based on these two designs and their functions, you can decide which uninterruptible power supply system is right for you. 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.
