What is a UPS?

A Device with a battery to provide electricity in the event of a power cut. It also protects computers and data from power disturbances. It provides time to save files and shut down computer systems in an orderly manner. It is an emergency power, life support system for computers and information.

What is the difference between a modified sine and pure sine wave inverter?

Modified Sine Wave:The most common, general-use inverters available are of the "Modified Sine Wave" variety, usually available at more moderate pricing compared to pure sine wave models. Although designed emulate a Pure Sine Wave output, Modified Square Wave inverters do not offer the same perfect electrical output. As such, a negative by-product of modified output units is electrical noise, which can prevent these inverters from properly powering certain loads. Pure Sine Wave:Pure Sine Wave inverters provide electrical power similar to the utility power you receive from the outlets in your home or office, which is highly reliable and does not produce electrical noise interference associated with the other types of inverters. With its "perfect" sine wave output, the power produced by the inverter fully assures that your sensitive loads will be correctly powered, with no interference. Some appliances which are likely to require Pure Sine Wave include computers, digital clocks, battery chargers, light dimmers, variable speed motors, and audio/visual equipment. If your application is an important video presentation at work, opera on your expensive sound system, surveillance video, a telecommunications application, any calibrated measuring equipment, or any other sensitive load, you must use a Pure Sine Wave inverter.

What can I use one for?

The inverter draws its power from a 12 Volt battery (preferably deep-cycle), or several batteries wired in parallel. The battery will need to be recharged as the power is drawn out of it by the inverter. The battery can be recharged by running the automobile motor, or a gas generator, solar panels, or wind. Or you can use a battery charger plugged into an AC outlet to recharge the battery.

What does a Power Inverter do?

A power inverter changes DC power from a battery into conventional AC power that you can use to operate all kinds of devices ... electric lights, kitchen appliances, microwaves, power tools, TVs, radios, computers, to name just a few. You just connect the inverter to a battery, and plug your AC devices into the inverter ... and you've got portable power ... whenever and wherever you need it.

What is a Power Inverter?

It is a device that converts electrical power from DC voltage to AC power. Its typical application is to convert battery voltage into conventional AC voltage allowing you to use critical load when an AC power source is not available.
