    TB6560AHQ burned

    Hi;

    I have connected the power supply to a Driver Board TB6560AHQ, and this board began to burn (smoke came out). The power supply is a 24V 15A. With a tester I mesure 28V in the power supply. I just have connected the power supply to the board (without motors).

    Alguien puede decirme por favor que paso? y como puedo evitarlo?

    Thanks a lot for your help.

    28V will be correct. This is the no load voltage. It will drop to 24v under load.
    I have looked up the data sheet for for this device and the is no reason for the smoke to come out without motors connected unless the polarity of the supply is reversed or the supply is 28v AC not DC
