    Hi everyone, New to the forum.. I'm in the fluid power field and need some help with the electrical side of a power unit.

    I have a customer with a 5HP 3 phase motor running a press. Customer wants to install a bigger motor (15HP) and add some controls. My Micro controller is rated 9-36vdc max current the controller can handle is 8amps. How can I operate the electric motor with 230AC and also convert AC to DC?
    How do I convert the AC to DC also?
    If further information is required I am all ears! I'm totally ignorant to electrical.

    for the DC side, purchase a power supply rated for your 230VAC input and desired output. 24vdc is a common output for industrial applications. Something like this http://www.meanwell.com/search/nes-200/default.htm

    On the motor side, we'll assume you have 240vac 3 phase available. Motor circuits require an overcurrent device on all ungrounded conductors, a suitable disconnect, and overload protection. Throw in properly sized conductors on both branch and feeder, with feeder overcurrent, and you'll see that a qualified electrician is a necessity.
