I've done some preliminary research and have not found a real answer.
I'm purchasing power inverters for a project. I'm see typically 50 hz for "pure" sine wave inverters, and 60 hz for "modified" sine wave inverters.
The US power grid is 60 hz. So then is it modified or pure.
There's lots of sales related text stating various electronics must or should have pure sine wave, but I've run my computer tower on modified sine wave and batter chargers too. My computer's power supply states 60 hz. and runs fine on a cheap 700 watt modified sine wave inverter.
So is 50 hertz pure sine wave and 60 hertz, modified, or like in the US power grid, is 60hz pure sine or modified sine?
Pure sine wave inverters are 3 times the cost. I have to wonder if this is mostly a sales gimmick.
