Re: Avalon, and Lockout for Safety



Chris, and Terry

If a railroad right of way "siding" is in the area a used diesel locomotive
could be used.  A typical GP40-2 has a 5MW alternator on it, and the
dash 2 modular electronics means full control of output by three PCB's
run on 48VDC.  What could we do with 600V 3ph at 5MW...

Warning, warning, off topic alert!!!
