does this unit put out pure sine wave or modified sine wave

Wish I could help. Still trying to figure mine out. Instructions leave a lot to be desired

Modified sine wave. This inverter will not perform as advertised. Very weak.

you connect the different modules together, often in interesting ways. For example...a sine wave oscillator can be used to make a pure tone, OR you can slow it WAY down and use the patch cord to control an audio filter to make an undulating wah-wah tone. You don't hear the sine wave, you use it to control some other function. This was Moog's original innovation and is used time and time again in modular synthesizers (and in digital ones, but the connection is less obvious when you're just adjusting parameters on a screen).

Yes, it outputs 60 Hz but DOES NOT output a sine wave. Small inverters of this type put out what is sometimes called "dirty" 60Hz power, which is perfectly fine for most (modern) digital electronics, incandescent lights, and SOME motors. It is not good for other kinds of motors some fluorescent lights, and many analog audio systems (you'll hear a hum). I'm afraid I don't know which motors are OK and which are not.

The output is a modified sine wave, though I don't know what it looks like. I picture it being a pixellated version of the real thing, with an unknown number of successive approximations to the sinusoid (like, step functions rising to .3, .5, .7, 1.0, then down again). I have used the unit to feed into the external power supply to my MS Surface pro, and it worked fine for the last two summers on a fire lookout. As I remember, sometimes it appeared not be charging the batteries in the Surface, but then, later, they would be charged. That might have been a spurious interpretation by the power monitor in the computer. Anyway, it was an excellent solution for back-country use.

No, see other responses. Not quite Pure Sine Wave. Apple products won't charge from this inverter. Mine blew out a control IC to the output stage after the 90 warrant expired.

It is not a pure sine wave inverter. That being said, it will operate 90% of anything you would want to run with no problems.

Fridge doesn't require an expensive pure sine wave inverter, run it off a 2KW cheap inverter. You're overloading this inverter on startup with your fridge. I've run all my fridges/freezers and even computers for years off cheap inverters. TV's and other devices that sing from from the non-pure sine wave need a better inverter.

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

Been using it non stop for a year (i.e., has been connected to power and running computers and printer etc.) have not had any problems. And yes it is a true sine wave. Laser printer and NuWave PIC work fine on it.

My Sunforce 11240 Pure Sine Wave Unit has been working fine. Remote responds readily. Runs lights in my garage and small air compressor at various times. Well pleased with its performance. Remember, when you use more than 80% of your machine's capacity on a regular basis you may cause a premature failure of your equipment. As long as you don't put a really heavy load on the unit that pushes it to the max, you should get good service out of this inverter. Mine has been in service for almost a year with no problems.

No for the price and you want the direction of the different sounds each unit makes. They all work on a different sound frequency, I currently have 2 units it is working great for the situation I'm. . In, they are a blessing!!!! Work great,

Digital audio input jack only, no digital output jack. But dont buy this unit, it is crap. There is no way you can get 1000 watts from a unit that only draws 150 watts from your power company. Their claim is fraudulant.

I don't know, but I think it can not. There is only a small software to generate waveforms.

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

Not this one, it has a 50 Hz output and may damage your TV. Consider something such as a Xantrex or other brand of pure sine wave inverter.

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