Pure Sine Wave 

  1. The PowMr Power Inverters output a pure sine wave is similar to the waveform of the grid power. 
  2. In a pure sine wave, the voltage rises and falls in a smooth fashion with very low harmonic distortion and cleaner utility-like power. 
  3. This gives users stable enough power to operate tools, fans, lights, computers, and other electronics without any interference. 
  4. pure sine wave inverters are in many cases more efficient, allowing users to use less energy and allow for more device capability. 
  5. The main advantage of pure sine wave inverters is that they are used to operate sensitive electronic devices that require a high-quality waveform with little harmonic distortion. 
  6. Almost any electronic device could be powered using a pure sine wave inverter.
