    ​The i Series System separates the fence information from the Energizer. This means the Energizer can still be hidden away where you’ve always kept it, at the back of the shed, but you can position the Energizer Controller where it is more accessible (up to 164') away from the Energizer.

    The Controller shows all of your fence performance information (e.g. voltage, faults and location) in one convenient separate display box – providing greater visibility and control.
