I'm looking at inverters as a solution. We have several generators (they increase throttle based on load and generally have very unclean power).
We also have one Sear Alternator that runs at a constant RPM and provides some of the cleanest power I've ever seen. 60Hz on the nose @ 120volts. As you load it, the voltage slowly goes down, but the Hz remains constant. On 5/8/13 1:00 PM, Chris Fabien wrote: > I am not sure exactly what you are getting at by using the term > alternator.
