subject: Buying an Unnecessarily Expensive and Bigger UPS [print this page] As the frequency of power cuts increasing all over the world due to a high shortage of electricity, the uninterruptible power supplies (UPS) have become a basic need not only commercially but also in domestic usage. With the help of UPS you can save the electronic equipments like computer from a sudden breakdown due to variation in voltage. With this, it also provides an extra amount of time to save and manage the work when power is gone, which in turn ensures safety of the data in case of a sudden power cut.
At present, a large range of UPS is available in the market along with a varying degree of battery back-up and power protraction capacities, and one should purchase a UPS which perfectly suits their requirements and preferences. There is a wide spread phenomenon in the market that a UPS with higher price tag comes with comparatively more efficiency and more utility. But that's not true as buying an unnecessarily expensive and bigger UPS will not only make a big dent in your pocket but also will be more hectic to use and place. Thus, before going to buy a UPS in the market, you should pin-point your needs from this prospective UPS so that you can enjoy a hassle-free utilization.
At present, there are three types of UPS available in the market that comprises of Off-line UPS, line-interactive UPS, and on-line UPS. The basic and the lowest-priced among these three is off-line UPS that offers a limited surge protection and battery backup. The off-line UPS offers an very distorted quasi-sine output.
There is no provision of power conditioning in these types of power supplies as it feds directly to the output of the UPS when in utility power mode. The next range of UPS is Line-interactive UPS which is though very similar to its Off-line counterpart, but carries an internal automatic voltage regulation (AVR) that enables it in maintaining some output voltage regulation.
But same as Off-line UPS, it doesn't perform the task of power conditioning. The last and the most sophisticated is the on-line UPS which converts the ac to a regulated dc as soon as you power it by a utility source. Be it battery mode or be it utility mode, the on-line UPS always provides a clean and true sine-wave output power. You can buy easily other computer accessories through online shopping in India.
