I bet my rambling was just unclear! Currently it has a 3 phase 240->72 volt transformer. When I convert it to EMC I want to be able to run it on my single phase power. So I have a 415->120 single phase transformer that I will use instead of the current one. I will run 240 into the 415 winding and get about 70 out. I will also probably have to upgrade the diodes and especially add some more capacitance. The transformer is so heavy because it's single phase; a single phase transformer has much more iron than a three phase of the same power rating. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
