    Powering Leadshine MA860 driver with AC transformer

    Hello everybody,

    The Leadshine MA860 driver contains a bridge rectifier and I think 2 capacitors with a relatively small capacitance inside it,
    I think that the DC current is not smoothing enough when powering it with AC transformer. (sorry if I am wrong!)

    - Is it normal? or it causes more heating and vibration to the motors?
    - How to size the transformer and how the back EMF energy is absorbed since we have not big capacitors?

    Thanks for your help!

    I use 60VDC to power up MA860, it works OK. No need capacitors and back EMF energy circuitry.

    Thanks for your reply,
    You used 60VDC, you mean DC current?
    What I want is how to size the transformer to power up MA860 with AC current?
