A little NME0505D is reasonably cheap, but only has 1 kv isolation, which is probably not enough for your high voltage use case. Maybe there are alternatives with higher isolation voltage? > On the other hand, if one where to go to the trouble to put an > AVR onto a KBIC, it would be better to just design a new DC motor drive > based on the AVR, maybe. Now that sounds like fun. :-) Erik -- If triangles had a god, he would have three sides. - Montesquieu ------------------------------------------------------------------------------ This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
