Have you ever wondered why some investors cost much more than others by the same force. I would like to describe briefly one of the main differences between an investor of low cost and high cost.

Searching for a power inverter to convert DC to AC may seem to be a simple task, but if you're buying an inverter for personal use, you will find that many of the decisions they face. With prices under $ 25 to over $ 1000,can be difficult to know which features are important and how to select a unit for matching.

During the performance you need and how to connect the device to its product supply are taken into account, another factor to be taken into account, the waveform of the inverter output. There are two general types of investors: true-sine wave or modified sine wave (rectangle). True sinewave inverters energy production that are identical or sometimesslightly better in the power of the power network of public utilities. The wave of energy when displayed on an oscilloscope with a smooth sine wave. Modified sine wave inverters and square are the most common types of investors in the market. Modified sine wave inverters produce a wave of energy that is sufficient for most devices. The power curve is not exactly the same as grid electricity. It has a waveform as a square wave chopped when they have had aOscilloscope. What does this mean for the average user? Not much. Most electrical appliances work just fine in both types of waveform.

Most of our customers who use an inverter to run find a laptop computer, A / C charger cell phone, fan, or the camera that a modified sine wave inverter operates through the cigarette lighter that the easiest way use.

Generally recommended choice for investors who are rated less than 300 watts, when the 12-V –Cigarette lighter on most vehicles. We recommend that, because of its support for up to 300 watts for the inverter, the fuses in the car starts to blow. There are several units in the market driven between 100-200 watts, which plugs directly into vehicle cigarette lighter. It has only one exit, but after a 12-volt outlet, all that is necessary for the operation, can not overcome by the ease of use. These small units often provide approximately 150 wattscontinuous operation and generally have a built-in surge protector.

Square Wave units, or low cost inverter can be divided into three categories:

Desktops 500W or less for household appliances, TV (up to 19 "), video recorders, mobile other office equipment. Most of this compound in a 12-volt plug.

501-999w for appliances, big screen TVs, 5 power tools, machines and bread. Most of these investors are directly connected to the battery of 12 volts, and havethree or more points of sale of land to feed several products at once.

1000-3900W microwave, electric tools larger, toaster and hairdryer. All investors of the thesis are designed for direct connection to the network of the battery and can usually 750 - 2500 watts of continuous power.

The problem with the waveform only comes into play when specialized pieces of equipment should be supplied with electricity. Here are a few devices that could have problems ifare an investor, a modification of the sine wave signal: oxygen concentrators, fax machines, laser printers, high-voltage chargers wireless tools, equipment with variable speed motors, electric shavers generate linked and garage door opener . For most applications of others, you can go with low-cost investor.

Finally, there is not really necessary to bring the average user with a true sine wave unit. The modified sine wave in most low cost find investorsbe sufficient to care for their applications.
