Is this modified or pure sine wave?

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

Peetty sure it is modified. Dont know ecatly what true sine is. Goes to the manifactures web page. They explain

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

Modified Sine. So it's not as good as a pure Sine. Depends on the electronics you're trying to use. Laptop or PC should be fine. High end test equipment, medical devices, you would be better with pure sine.

It's a pure sine wave output, so there's no difference in the output. the second back up wouldn't know the difference.

the tripplite produces pulse modulated modified sine wave it is substantially cleaner than a low end modified inverter and should have no problem starting or running any 25 foot or less refrigerator

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.

Are you using an inverter, I had the same problem, it will only heat when using a pure sine inverter

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

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

To answer your question, I just walked down to the basement and plugged my 48V Genssi power supply powering a DC fan into an APC BackUPS 500, pulled the input plug on the UPS (which causes the UPS to output a modified sine wave) and it had no effect on the operation of the power supply. I ran the fan from low speed to high, then plugged the UPS back into the wall to switch it back a pure sine, but I could detect no effect on the power supply. I hope that helps.

Yes it does! I'm not sure how to read it but I think it's common sense, ie stable repetitive wave vs choppy, spikey and "flatty". I cross checked the readings @ Dr's office, checked good. Merry Christmas.

it is a pure sine inverter. The Flicker is caused by the deadtime at the zero crossing, adding a small resistive 100 watt load smooth's the output to where the flicker goes away.

No its a modified sine wave. Do not purchase this inverter it has a 50 cycle 120v output. It will not work for many North American rated devices. The stated specifications are incorrect.

this inverter is a under powered inverter. go with a aims inverter!! I picked up a pure sine wave aims inverter and have been loving it.

If you use a modified sine inverter with an led tv you will not like your picture. You should use a pure sine. Also your tv will last longer on a pure sine.Joe
