hi, whta's the difference between pure sine wave and modified sine wave thanks

Answer from Wikipedia: A power inverter device which produces a smooth sinusoidal AC waveform is referred to as a sine wave inverter. To more clearly distinguish from "modified sine wave" or other creative terminology, the phrase pure sine wave inverter is sometimes used. The terminology "modified sine wave" has come into use and refers to an output waveform that is a useful rough approximation of a sine wave for power translation purposes.

I purchased one about a year ago. I returned it because when I connected my iPad to it, the iPad went crazy. I was using the stock power supply that came with it. I tested this several times before I returned it. To answer your question, it is probably NOT a pure sine wave inverter. I ended up getting a Xantrex Prowatt pure sine wave inverter.

See no difference in the two. Very pleased with themNot sure about interchanging but they have their own coupler and it works fine.With the money, don't spend More if need not needed.

Hi Gary,The Nature Power Solar Home and RV Kit with 40 Watt Solar Panel, 1800 Watt Inverter and 60 Amp Battery has a modified sine wave inverter. Please feel free to contact Earthtech Products if you have any additional questions.Best regards,Earthtech Products Customer Service

Unsure what the difference is. Id just ask them! http://www.pac-audio.com/contact.aspx keep us posted!

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.

The most major difference I see is the resolution, reference these two pages side by side to note the other differences. http://www.casio-projectors.eu/uk/products/xja155/ and http://www.casio-projectors.eu/uk/products/xja256/

This is a modified sine inverter, as such there is a distortion which you can hear when you use this with some devices such as box fans.

While it is true that a modified sine wave inverter may damage certain types of electronic devices, that's really more of the exception than the rule. There are two different things that you need to be concerned about: appliances that use AC motors and certain classes of delicate medical equipment. If your electronics don't fall into either of those categories, then you're good to go with a modified sine wave inverter - and you saved a bunch of money to boot. reference to above information. http://cartech.about.com/od/Power/f/Will-A-Modified-Sine-Wave-Inverter-Damage-My-Electronics.htm While it is true that a modified sine wave inverter may damage certain types of electronic devices, that's really more of the exception than the rule.

Pure sine wave will always be the default recommendation, especially for electronics. However there is generally a big cost hit with pure sine wave compared to simulated sine wave. For a unit like a power supply which is quite robust in design, when talking about the quality of power input, a simulated sine wave UPS would be acceptable to use. It is certainly much better than exposing the PSU & your PC to power brownouts.

The "pure sine wave" inverter can help running some things and eliminate a sound "Buzz" that can come from the cheaper "modified sine wave" inverters running radios & such. However, I'm not sure for a laptop that it will make that big a difference since the power is converted back to DC anyway (where it almost seems funny to take DC power, change it to AC just to go back to DC).

Sorry but I'm not know exactly the difference. I had this model and it works very well.

Frank, I don't know how it would respond to the modified sine wave but maybe there is an easier solution. From the nature of your question and this device I assume you are starting with a DC power source (12v car battery?), inverting it to 120v AC, and then converting it back to 48v DC with this power supply? If that is the case then you could skip a step and achieve greater efficiency by just using a DC voltage regulator that allows you to step up the voltage--Amazon sells them (eg. http://www.amazon.com/DROK-Converter-Voltage-Regulator-Charger/dp/B00BZR9PBW/ref=sr_1_1?ie=UTF8&qid;=1393267559&sr;=8-1&keywo;rds=12v+to+48v+converter). I hope this helps! Frank, I don't know how it would respond to the modified sine wave but maybe there is an easier solution.

modified sine wave.....i use mine to run the washer and dryer , it works fine for that

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).

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

Says it is full sine but I couldn't tell because as soon as I tried it, it quit working before it even started.
