    Hello All,

    I'm trying to build a small control panel to operate a series of 24V
    solenoid valves. A maximum of 2 valves would be working at any given time,
    how would I size the power supply. (120 VAC supply).

    Any suggestions on power supply manufacturers? Any with built in fuses?

    Can you get a data sheet from the valve manufacturerers?
    This would give you the "Pull In" & "Hold On" Currents,
    you will need these to accuratly gauge the size of psu required.

    Also are they 24dc or 24ac?

    Don't most solenoids come with protection from back emf built in?...that
    would be a diode of course....Ross
