What Is A Pure Sine Wave 12 Volt Inverter?
A power inverter is a very handy device to have. Many people who don’t know very much about purchasing a 12v power inverter turn to the Internet as a source of information. While the Internet is an amazing tool when it comes to learning about 12v interters, it can leave someone who is new to power inverters quite confused. Here’s a handy little bit of information about power inverters.
Power that is delivered to your home from the electric company is fairly clean power. This means that the quality of power is quite high. Some power inverters output power that is not as good quality as the power that you receive from the power company. There is a device called an oscilloscope that electricians use to measure power quality. Very low quality power inverters output what is called square sign wave power. Many Electronic Devices may have difficulty running on an inverter that outputs square sine wave power.
Most power inverters output what is called modified sign wave power. This is close to the quality of power that you receive in your home and is adequate for almost all applications. Then there are power inverters that output what is called pure sine wave power. These power inverters are generally quite expensive. These units are capable of powering the most sensitive of electronic devices.
Some would have you believe that you need a pure sine wave inverter for things like laptop computers but that’s not really the case. For most applications a modified sine wave inverter will work just fine. While it is true that a pure sine wave inverter outputs the cleanest possible power, the reality of it is that most electronic devices are built to function just fine if the power isn’t of the highest quality. Manufacturers realize that their devices will be used under a variety of situations and the quality of power from location to location can vary. As a result, they build their equipment so that is capable of running on dirty power.
So if you were in the market for a power inverter, unless you are overflowing with money and can afford the high and pure sign wave unit, a well made a modified sign wave unit should suit your needs just fine.
