The Basic UPS Guide

It could occur to you at any time, and in a blink of an eye. All it takes is a small spike, surge, brownout, or any other variation in the voltage and your gear can be eternally damaged, your data shattered, and your operating system files tainted. Faulty electrical power can insidiously wear down your system over a period of time, without you knowing – till – ultimately, it fails. One way of evading such adversity is to fit a UPS. A UPS (Uninterrupted Power Supply) is a power supply that includes a battery to support power in the event of a power outage. Most UPS units will also filter and control the utility power. A UPS can be used on most electronic gear, although this piece of writing will focus mainly on its usage with computers. There are essentially 3 types of UPSs to select from. Keep in mind that Online UPS Manufacturers in India have their own design and changes. The types are as follows:

Offline (Standby) UPS

The standby UPS is the simplest and least pricey UPS design. Getting its main power from the AC line (i.e. your outlet), this type of UPS switches over to the backup battery mechanically when any drop in voltage is detected. When the power is returned, the UPS then switches back. This UPS has nothing to control the electricity although Online UPS Manufacturers in India may include some sort of line sift.

Line-Interactive UPS

Hailed by some to be the most well-organized UPS, the line-interactive UPS is one of the most well-liked designs used today for computer fortification. Although some manufacturers sell line-interactive UPSs which are no more than an offline UPS with a regulator added, the essential line-interactive UPS has a bi-directional inverter/charger which is always linked to the output of the UPS and makes use of a portion of AC power to keep the battery charged. When the input power fails, the transfer switch disconnects AC input and the battery/inverter provides output power. This gives a faster reply to a power failure than an offline UPS.

Online UPS

This design is measured to be a “true” UPS. Not like other types of UPS, this one uses the battery as its main resource of power and the line power is the resulting source of power. When line power goes out the UPS does not have to change from one power source to another, it just stops charging the battery. This is alike to the way laptops react when they are unplugged from line power. When there isn’t any line power, the battery will remain to power the system till its stored power is exhausted. Since this type of UPS design runs off the battery, the gear plugged into it will always retain a constant flow of power. Any surges or brownouts will be taken in at the battery charger and not passed on to the gear. Being more composite, online UPS units usually costs more than offline units.
