494	Hello fellow Mugs I am having a bit of bother with turning a motor on an off with a relay. Oh I can turn it on an off all right. The problem is when I turn off...	Chris Holme cholme@...	May 17, 2004 2:37 am

502	... Yep. Although the transorbs are rated to handle a specific minimum energy (1500 Joules in the case of the 1.5KEnCA I think), while the shottky's aren't...	David Emrich dave_emrich	May 17, 2004 4:04 pm
