Is this a pure sine wave??

NO! This device will not work with some sensitive electronic equipment! It does not work for both of my Lithium battery chargers for my electric bikes. THis was a waste of money, Buy some thing else for battery chargers.

I only used this inverter for a very short time and it worked well. Did not get a chance to verify if it was pure sine wave as I upgraded to a 24 volts inverter within short time

I have this inverter, and my understanding is that it is pure sine wave. I use it to power my entire vacation house on a Caribbean island with no troubles, save for the fact that the vacuum cannot run at the same time as anything else.

With no way for me to test the unit i would say this much have one i bought at gun show that claimed to be tactical stun device with approx 11 million volts , i paid 49 bucks for it and its not as hot as this one , the volts are not as important as the sine wave put out and i am not trying either of these on anyone ! unless needed ! They where also selling this one at gun show for 80 bucks but didn't buy it there, i bought it here on Amazon and have given 4 away to those at risk of home invasion due to no guns ! P.S. i will be buying more of these for Christmas gifts !

well, because is for relaxing, the music is low volume or with headphones but is from an outside device (TV or cell phone) no through the device itself. as per my understanding the sound from the device was not the best but I don't recall that the sound coming from the device change the pace of the wave effects... thanks for point it out I will check it out, but any how as it is the wave pace is perfect.

Brian, the PV2000FC maintains a PWM sine wave output voltage of 120 V AC (+/- 5%). If you are looking for a pure sine wave inverter, I would recommend our APS2012SW (ASIN: B006R64SUE), a 2000W PowerVerter with Pure Sine Wave Output.

Pure sine wave is the best way to go. I've had modified sine before and while they do work for most things, induction motors and microwaves don't put out full power and are noisier. I bought a 2800 watt Magnum Energy pure sine wave and have never looked back.

When I purchased mine I got the answer to that in the literature that it came with as a modified Sine wave. However unless you are using this for medical physics the difference between the two is minimal. I hope that helps. Mine has worked fine for running a small refrigerator and TV while we camp.

The SMART1500LCDT has a PWM sine wave (Pulse-width modulation), not a pure sine wave. However, Tripp Lite carries many other 1500VA UPSs with a pure sine wave output. Also, please know that not all computers and electronics require a pure sine wave.

I'm pretty sure it is stereo. I used it this morning, and it sure sounded like it was.

I severely doubt it, because the sine waves would NOT be in synch and that would play havoc with any electronic devices attached, changing the RMS voltage outputs. It would create very dirty power. If you want to do this, you should contact the manufacturer to see if there is some modification they can recommend. Otherwise, just split the outputs to different circuits, but be very careful to NOT share a common neutral, and provide a separate ground as well.

I used a 'scope to fine adjust the frequency and seem to recall it was close to a pure sine wave, quite clean power. It powers all our electronic equipment without a problem. I adjusted the frequency using the peaks of the waves to stop our UPS's from complaining

It takes 12 volt DC input and turns it into pure sine wave 115 volt AC. It only works between 10.5 and 14 volts input.

No, the inverter is Modifyed, we can supply a pure syne wave for an additional $150.00 Thanks, OG Solar

I got the below from Tom's Hardware from someone who asked the same question and the answer they received from CyberPower: "I received the following answer from Pietro Boggio, Senior Technical Support Specialist at CyberPower: "No digitally created wave can be a true mathematically curved analog wave. But the number of digital steps used to create the wave can be great enough that the electronics used in even the highest efficiency computer power supplies are unable to distinguish them from an analog wave. The total harmonic distortion of the output on battery is under 2% which means the output of the UPS is closer to a mathematically ideal analog wave than the powercoming out most peoples walls. "These units were created specifically for the needs of computer users with Active PFC power supplies. We put PFC in the model name to highlight the fact that these units are compatible with Active PFC Power Supplies." I can tell you I have the CyberPower CP1000PFCLCD PFC Sinewave UPS 1000VA 600W PFC Compatible Mini-Tower and I've had zero problems with it, my power has gone off several times since I've owned the unit and I have lots of sensitive equipment plugged into it.

This unit has excellent frequency stability and as far as generated harmonics are concerned I did not detect any of any measurability. It has an rf frequency chip from Japan that has rave reviews. So you shouldn't have to worry about it.It produces very high fidelity stereo sound and I would recommend it to anyone who'd buy it. I hope this is helpful to you.Regards,Greg

No it is a modified wave inverter. You may experience problems or may not. I am not an expert. I plan on powering my APC/UPS 750 backup supply with this inverter to run my computers. My backup is a pure sine wave inverter/power surge protector. I have used modified wave inverters for appliances and had no problems. Most experts do recommend pure sine wave for computers,TVs,etc. but I am not an expert. I do know pure sine wave inverters cost much more. Andy

I am not sure, but I think it is a modified sine wave. I thought a pure sine wave inverter would be more expensive.
