If we talk about commonly used electrical apparatus, then UPS (Uninterruptible Power Supply also commonly known as Uninterruptible Power Source) may hit somewhere around the top of the list. Vacker Nigeria supplies a variety of models of UPS that come in different sizes and various power capacities in cities such as Lagos, Abuja, Kaduna, Port Harcourt, Aba, Ibadan and Kano. These devices are also known as flywheel backup. They provide emergency power backup to the electrical devices that are connected to it. The power backup thus provided is uninterruptible in nature which means that the connected electrical device will not have a pause or break in operation and can perform operation in a non-discrete manner. Because of this nature this apparatus is called uninterruptible power supply.
These devices are connected to other electrical devices that work on mains power supply. In case of power failure a UPS will supply an uninterrupted power to those devices hence facilitating in uninterrupted operation of the device. These devices differ from other emergency power system and generators that supply a discrete supply immediately post power interruption. A UPS has an in-built battery provision that supplies uninterrupted power to the connected equipment to an extent that the unsaved data can be saved and they system can be safely shut down.
If you have a computer or any other electrical equipment then a UPS can be of great help. At times of unexpected power failure, a UPS will protect your hardware/software from any possible injuries and eventually prevent data loss of any kinds. UPS is generally of small size and capacity but the largest UPS of the world (Battery Electric Storage System) of Alaska is of 46 Megawatt.
Significance of UPS:
As we know that UPS is used so that one can have an advantage of saving unsaved data with a supplement of short term power. UPS is also used to overcome some common problems mentioned below:
- Saving electrical equipments from default of voltage fluctuation.
- Sustainable input voltage cut.
- Mains frequency instability.
- Helps in Harmonic distortion.
Modern Advancement in UPS:
In the modern advancement in UPS systems, 3 categories can be found:
- On-Line UPS: It uses rechargeable batteries and converts AC to DC.
- Line-interactive UPS: It redirects the DC current from the battery from the normal mode of charging.
- Standby UPS: It is also known as the off-line UPS. It starts when the main line interrupts the supply.
As a latest trend in UPS system, a new system named Fuel cell UPS has been developed that uses hydrogen along with a fuel cell that acts as the source of power to the UPS system. These UPS have the capacity of providing back up for a comparatively longer run but occupy very small space.
