Jeff, Many aircraft that I've had the pleasure of working on have DC to AC inverters, The OV-1D Mohawk has 2 such devices, which are basicly a High Speed 24 volt DC motor, spinning an AC generator. This gives "true" 120 volt AC power (true oscilating inverted sine wave like: ~~). The problem with this style inverter is that they are expensive, heavy and noisy. They also generate a substantial amount of heat, and they require a substantial amount of DC current to run them.
As an alternative, the other style is a solid state inverter, however, it's output is pulsed AC, (the sine wave looks like multiple top-hats put end for end like: _-_-_ ). So depending upon the instrument power requirements, this may be an alternative. The advantages are that they are silent, have moderate DC power input requirements, moderately priced and are fairly lightweight. However they may cause electrical interference with your radios and other electrical equipment. So it's probably manditory to use shielded twisted pair wiring to prevent the interference problems. These are the same style and type units used in autos, RV's etc. (Wall-Mart actually sells versions of these units) I don't recall if I've ever seen one for Aero use, but you could check with AC Spruce or Wick's. And as always; your results may vary.... wilder_jeff Wilder <wilder_j...@msn.com> wrote: I bought an R.C. Allan Gyro off of ebay last week... I received the product, it was as described.. but when I was bidding on it, I did not realize that it was 115v AC 400mzh. UHHGGG!!! once again. Anyone know if I can convert this to 12v dc?
