There are many models of frequency inverters, of which true sine wave inverters (a.k.a. sinusoidal inverters) and modified non-sinusoidal models are the most popular. When it comes time to buy a frequency inverter, some companies are not sure exactly which model to buy. There are pros and cons to each choice, but true sine wave inverters typically come out on top in a side by side comparison. Below is an overview of how the devices stack up when compared to each other.
Cost
Sinusoidal models typically cost more than other models due to the sensitive technology they contain. However, as time passes, the devices continue to become less expensive. Today, the cost differential between the models is slim enough that no company should have to buy a model that is not the best option in order to stay within the electrical budget.
Distortion
Some models emit more harmonic distortion than others, with non-sinusoidal models emitting the most, and sinusoidal models emitting the least. Harmonic distortion is measured in a percentage that is expressed as Total Harmonic Distortion (THD). THD over 3.5% often causes electrical equipment that requires a sinusoidal current to exhibit the significant signs harmonic distortion.
Usability
Modified models are usable with a limited range of equipment, equipment that does not require a pure, sinusoidal current. Devices that emit sinusoidal current, on the other hand, can be used with a broad variety of equipment. Sinusoidal current is compatible with far more devices than non-sinusoidal current, and is thus a more sensible choice when it comes to usability.
Longevity
As long as reputable manufacturers produce them, different brands and models of frequency inverters have roughly the same lifespan. However, because they can be used with a broad variety of equipment, devices that emit a sinusoidal current have a longer useful lifespan than other models, which are often replaced to accommodate new equipment that requires sinusoidal current.
Conclusion
True sine wave inverters may cost more than their counterparts, but they emit a lower level of THD, are usable with practically all types of equipment, and tend to have a longer useful lifespan due to their broad range of use. There are various concerns that go into choosing a frequency inverter in addition to the ones listed above. If your company needs a frequency and isn't sure which kind to choose, contact a seller of electricity conduction equipment to receive assistance.
