First off I’ve been really tearing it up in my nerdery the last two weeks… It’s messy.. That happens so don’t mind the mess.

So I scored this sweet variable frequency drive (VFD) or also known as a VSD. It’s a Rockwell Automation drive that is to large for my application but it’ll work just fine. I figured I might have to tear out the entire front because I’m feeding it straight DC but they broke out DC to a terminal block ?! I’ll give it a try… I have a 96V power supply that was a long shot but it was no surprise two amps wasn’t enough just to power the electronics for configuration. It isn’t jumped to run… So this beast is a watt-hog just idling. I have a couple batteries I have to pick up in a few days; I am guessing I can start it up on a 48V/19AH string. The power down defaults to zero and I believe it’s set up to run on just enough to run the electronics. I guess I’ll see?! If this doesn’t run on DC (and maybe even if) I’ll gut the AC front end because it’s extra weight. Check out the terminal strip..DC is on the left. Also… In case you’re wondering its about 90lbs.. A lot of heat sink!
