The incoming AC line is a sine wave, thus electronic equipment expects to see this type of waveform.A sine wave is the most expensive output form for UPS manufacturers to produce due to more complex circuitry and components.All Minuteman UPSs that produce a sine wave output go one step further by producing a synchronized sine wave.This feature eliminates the problem of an out of phase wave at the output.
Best True Sine Wave Ups Series From MinutemanEndeavor, Encompass, and EnterprisePlus series from Minuteman provide a true sine wave output. This type of waveform is quite suitable for virtually all electronic business equipment. Minutemans Enspire, Entrust LCD, and PRO-RT2U Series produce a simulated sine wave output. High end UPSs such as Minutemans Endeavor series produce true sine wave power through an AC-DC-AC conversion process. While not ideal, the modified square wave has peak voltages close to a pure sine wave, and an overall shape which closely resembles this ideal form. Many of Minutemans standby and line interactive UPS models make use of this architecture to maintain a balance between performance and cost. Peak voltage of this wave is lower than a sine wave of the same total power output, and the waves can also contain dangerous high frequency harmonics not present in a sine wave. Equipment running on square waves can experience operational problems, including heat buildup, and possible premature failure. LEARN MORE B. Walters Mt Pleasant, SC APC provided virtually no customer service. I had a problem at installation of MN 525 which was immediately addressed by Minuteman. Jeff, the technician who assisted me with an installation issue was knowledgeable, fast, efficient, and friendly.
