Sinewave vs Simulated Sinwave - Which is Best?
A sinewave output is the optimum waveform for electronic equipment. The incoming AC line is a sinewave, thus electronic equipment expects to see this type of waveform. A sinewave is the most expensive output form for UPS manufacturers to produce due to more complex circuitry and components. All Minuteman UPSs that produce a sinewave output go one step further by producing a synchronized sinewave. This feature eliminates the problem of an out of phase wave at the output. The Continuous Power, XRT, and PowerMind series from Minuteman provide a true sinewave output.
A pulse width modulated squarewave (also called simulated sinewave) is considerably easier to produce in a UPS. This type of waveform is quite suitable for virtually all electronic business equipment. Minuteman's Pro series produces a simulated sinewave output.
