A sine wave is a geometric waveform that oscillates (moves up, down, or side-to-side) periodically and is defined by the function y = sin x. In other words, it is an s-shaped, smooth wave that ...

Ashland, Mass. Schaefer Inc. announced the IV Series of DC/AC inverters that synchronizes three individual switch mode inverters and three output transformers, yielding a symmetrical 3-phase output.

The pure sine wave output lets the UPS exactly simulate the clean up and down cyclical waveform of normal electrical system alternating current (AC) power. Some UPS models produce a simulated sine ...
