I was able to locate a replacement SCR for these guys, since mine had shorted and blown a trace and the 47ohm resistors. Called up Littelfuse/Teccor they gave me great info, and ordered from Digikey this: S6010L. This replaces the special part number used between Teccor and KB Elec, A69104. The tech support guy knew exactly what I was repairing when I gave him that number! I also have speed controllers that use A69154, and since I didn't ask about these, I don't know if the replacement will work, but I assume so since the replacement, S6010L is rated at 600V 10A and has isolated tabs, well beyond the working range of either controllers. |
