How do we explain that, at times, our competitors use different levels of ohm load to state the Joule rating of their fencers?
As explained above the maximum output in to 500 ohms is limited to 5 joules, this does not mean that this is the max output to the fence line. As the load (resistance) on the fence line increases so does the joules consumption (up to a limit where the energiser can no longer supply the demand), but the line voltage drops in proportion until a point is reached where in spite of a high joules rate the resulting low voltage may be insufficient to repel the animal. i.e. As the resistance decreases the energiser has more work to do to maintain an effective voltage on the fence line. Most animals require at least 3000 volts. Therefore some manufacturers state the maximum output of the energiser, which can be quite high, but do not say what the output voltage is.

The STORED Energy of a fence controller is the amount of energy stored (Stored Joules) in a storage capacitor
