    sabvoton SVMC72200 blew on 1st run

    200amp controller low powered? lol i thought that was pretty strong.... if it acually peaks at 200 amps x 70v thats 14000w peak power. that should be plenty for the motor.

    sabvoton SVMC72200 blew on 1st run

    motor is a QS 273 8KW rated. its a big and heavy motor but the controller is 200amp peak. it shouldnt just blow under load and thats not even full load, maybe 50-60% if that.
