Computers, being extremely power sensitive equipments require a steady supply of power as long as they are switched on. Even a minor fluctuation in voltage or a drop in power supply can cause harm on the software as well as on the hardware of the entire system. This is why UPS Power System is absolutely necessary for computers, especially servers. The main task of UPS is to protect the computer from voltage fluctuations or discrepancy in power supply that may serious the health of the entire setup. There are different types of Uninterruptible Power Supply systems available in the market and so users have to make a careful choice from the options in hand.
Online UPS
This type of UPS is also known as Double-conversion UPS and is ideal for larger electrical installations. Traditionally these equipments have been used in industrial sector with a backup requirement of 10 kW or more. However, modern Online Uninterrupted Power Supply systems are also able to supply power as low as 500 W. In this system the batteries of the UPS are always connected with the inverter, thus eliminating the need of a power transfer switch. Though the initial cost of installation and operation is relatively higher, in the long run it yields a good return on investment.
Offline UPS
This type of UPS is the most basic type and is found in both domestic as well as industrial sectors. The basic design of the UPS is quite simple and it offers battery backup and surge protection to the computer. As soon as a fluctuation in the voltage is detected the DC-AC circuit inside the UPS is switched on and the equipment is connected to the output. Depending on the type of the UPS the switchover time may go up to 25 milliseconds. The sooner the equipment is able to detect the fluctuation, better is the protection of the computer system.
Nowadays it is possible to buy Computer UPS over the internet. Most of the UPS Manufacturers offer their products on sale through online stores. The main benefit of making an online purchase is that buyers do not have to go from one store to another searching for the products. They can sit at home and place an order over the internet, thus saving a lot of labor and time. However, it is always better to consult an expert professional before purchasing a UPS in order to get the best product in the market.
