Joules: Stored vs. Output
What is the difference?
Energizers generally have a capacitor that functions much like a holding tank. The energy builds up in the capacitor until it reaches a set level and then it discharges to the transformer. The transformer takes that energy and … transforms it by raising the voltage while reducing the amperage.
The problem here is that transformers are not 100% efficient in this transformation. Most are about 60-75% efficient. This means that if you measure the stored energy in the capacitor you may have 10 joules of stored energy. But once it goes through the transformer with a 60% efficiency level you will only have 6 joules output (10 x .6).
So marketing an energizer with stored joules, although accurate and legal, does not mean that the fence/wire will ever see that level of joules.
You can be comfortable in knowing that our energizers are marketing in a way that means something to the consumer. If we say there is a 6 joule output, that means the wire (and animal) will see/feel the 6 joules of energy.
