Know the Difference between a Low Cost Power Inverter and the More Expensive Models
Generally, there are two general
types of power inverters: true-sine wave or modified sine wave. power is
produced by the True-sine wave inverters. This poser is either identical or
sometimes better as the public utility power. Through an oscilloscope when the
power wave is viewed then it becomes a smooth sine wave.
In the market modified-sine wave
and square wave inverters are the most common types of power inverters USA. Modified-sine wave power inverters generate a power wave that is
sufficient for most devices. The power wave is not at all same as electricity
from the power grid. Appearing as a choppy squared-off wave, it has a waveform
when viewed through an oscilloscope.
Our customers who run a laptop,
a/c cell phone charger, fan, or camera are using a power inverter have seen
that the easiest to use is a modified-sine wave power inverter operating
through the cigarette lighter socket.
Despite using the 12-volt
cigarette lighter socket found in most vehicles we usually suggest you select
power inverters that are rated fewer than 300 watts. We advise you to select
this because the fuses in your car will begin to blow after you reach 300 watts
of the draw on the power inverter USA. In the market, there are
several units available that are powered between 100-200 watts that plug
directly into the cigarette lighter of a vehicle. These little units normally
have a built-in surge protector and usually supply around 150 watts of
continuous operation.
Generally, 750- 2500 watts of continuous power can be supplied by giving a connection to the battery network.
Only when specialized pieces of
equipment needs to be powered the problem with waveform comes into play. There
are a few devices that may have problems when they are connected to an LF
power inverter producing a modified-sine wave signal: equipment with
variable speed motors, oxygen concentrators, fax machines, high voltage
cordless tool chargers, electric shavers, laser printers, and garage door
openers. You can go with the low cost of a power inverter for other
applications.
