What type of AC output does it have: pure sine, modified sine, ...?

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.

It will verify your voltage but not your sine wave. Are you trying to measure frequency or peak waves?

yes the 3500 Watt w Pure Sine Wave portable inverter is very quite. we use it during hunting season at the camp it works well. love it.

The external power supply is a switching-type supply rated at 100 to 240 volts input at 1 ampere and input frequency 50 to 60 Hz. The output is rated at 15.0 volts at 1 ampere maximum with 15 watts maximum power output. No mention is made whether or not the power line input to the supply must be a sine wave. It is safest to assume that it must be a clean sine wave.

Hello, hhis pure sine wave inverter have input 12 VDC, output 110 VAC, the automatic switch we have con 110 vacío side

Modified sine wave. PURE would have been twice the cost so i settled for this one for my needs.

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.

No, it doesn't have 110VAC input, only 12vDC input. Nor is it a truly pure sine inverter, as I discovered after I installed it at my off-grid cabin. Not sure if I had a defective unit or not, but when using the inverter my cabin lights would flicker and it couldn't handle the load of an 800w microwave oven. I'm now looking for a replacement inverter from a more reputable brand.

No. You want a Grid Tie Inverter, search for that keyword. This only converts DC to PURE SINE A/C current. Pure Sine is the ONLY way to power sensitive electrnics like microwaves, TV, computer, etc.. Pretty much everything made with technology developed after the 70's. A/C motors can run on modified but they run cleaner and cooler on Pure Sine. Pure Sine is what you get from the mains. Modified sine is 1970's tech and good for things from that era, unless you like to buy whatever you plug in again and again and again and simply LOVE the sound of a constant buzz from whatever your using. IMO, Pure Sine or don't bother. But you want Grid Tie Plug and Play. I have them and they last and work well as long as the power is on, this one however is for when the power is OFF and you have batteries but need to run A/C appliances.

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.

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.

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.

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

Hello, hhis pure sine wave inverter have input 12 VDC, output 110 VAC, the automatic switch we have on 110VAC side if electricity fail, power inverter energize my house illumination

Hi Glen ,This is not a pure sine inverter.Please read the additional facts below.The inverter have three Power Index1.Marked power2.Peak Power3.Long time working powerNormal Output Power means the Peak power.Peak power is the moment Maximum power when we start the electric equipment.this peak power might be 1.5-3 timesDifferent electric equipment have different peak power. We need to know the rated power (Average Power) before we choose the Electric power supply ( like the inverter or battery). The power supply is 1.5-2 times. Electric equipment power,special electric equipment will need 3 times of Electric Power.General Average Power is counted according to 72% of peak power.This accounting methods usually is for small power electric equipment.

I would get a 3000 pure sine GP-SW3000-12. I can't find the 3000HD one to be UL listed.

AC 100-240V, 50/60Hz - this is the only one I have used (the one it came with)
