    Hi, does anyone of you guys use the Sabertooth 2x60 without batteries running 24VDC wheelchair motors? Maybe on clamp resistors ?

    follow the dimension engineering requirements... they state u have to have batteries.
    35 Amp hour minimum.

    Use of our motor drivers with cheap AC adapters is not recommended.
    Use a battery or at least put a battery in parallel with a DC supply.

    my understanding is for batteries to absorb the regen current.
    if not the motors will take it and heat up fast..

    thanks Hannibal. I was also in contact with Sabertooth Support and they said the same... I was just looking for a smaller setup without batteries but it seems that no one tried it with clamp resistors... I will be the first ... hopefully I don’t blow it up ;)

    But what type of rig do you want to build? Will the 2x32 be suitable.
