UPS - Simulated or Pure Sine Wave?

Tommy-boy · 11th February 2010

I've been looking in to UPSs lately and noticed that some have pure sine wave output, while others are similated.

This is really not an area I know much about, so my question is this.....Does it matter? Is it really important to have a true sign wave output, or is similated good enough? What people on this forum use?

Thanks,
Tom

It depends on the equipment but sine it is.

None sine inverters have lots of high frequency garbage which can sneek into the audio circuits and cause hum/buz/noise and intermodulation distortion.

Even with a sine inverter there are HF garbage and a mains filter can make sense between the inverter and audio gear.
