    Hello,
    I want to build a circuit that would supply a motor of the following type:
    Megamat MCZ 2 Easy

    This is used to move a patient chair in a linear monition up or down.
    These are the technical specifications:

    Please what are your suggestions Do I have to use a circuit with a power supply, or I can use battery powered circuit for this load? What parts do you recommend to use? relays are suitable ?

    You might also want to add a circuit to prevent sudden reversal of the motor.

    Forgot: on the subject of power you could just use a simple step down transformer and a bridge rectifier, the ebay type controllers usually have any capacitors built in.
    This is if the chair is used in just one permanent location.

    Sorry but what would be the cause of sudden reversal of the motor ?

    Sorry but Why do I need to use a PWM controller. Can't the motor be driven with a continued DC voltage ?

    Operator error.
    To avoid stress on the motor and its gearing the motor should halt before being reversed.

    Would you not need gradual action, rather than full on/off?

    No I think it's ok
    I just want to make it as simple as possible

    Then a simple joystick would work, you need a reversing relay unless the J.S. has enough contacts.
