    hi folks

    have a situation here where i want to run a antenna control board and an antenna rotator outdoors.
    the rotator is 220volts@ .5Aish and the control board is 12v dc @ 200mA

    what is the most convenient way to do this with an inverter?
    use a car battery? i cant hook the battery to the control board as it would fry it, any ideas out there?

    From what you're saying I'd have thought that you could just get a car battery and an inverter, use the inverter to power the 220v rotator and connect the 12V control board directly to the 12V battery.
    Why do you say the battery would fry the control board?

    This would be easier still if you had access to a 220V mains supply but I take it that this is a remote or portable rig?

    Would an old pc power supply do the trick?

    Chuckle just gave a mate a laptop and a 12v battery he got an inverter from Maplins for like 35 quid - makes a bit noise though:D

    presuming you want portability, as said before,...

    you could use an inverter from a car battery to run the "rotator",

    but depending on the power requirements of the control board you would prob need a regulated power supply to run from the battery. this is of course only if it hasen't alkready been designed to run of a car battery.

    when fully charged a car battery can given up to 16V, and as it drains this will drop below 12V, so most stuff designed for cars can tolerate large voltage variences
