The Patriot PE2 electric fence energizer is a 110-volt AC plug in 0.10 Joule model. Low impedance energizer designed to deliver power to the end of the fence, even under heavy load (foliage, undergrowth). Has a LED indicator that pulses when energizer is working. Easy installation. Distance range: 2 miles Distance range: 8 acres Peak Output Energy: Up to 0.1J Peak Stored Energy: Up to 0.16J Combine the PE2 with a 250ft spool of Patriot Made n the U.S.A. 17 gauge aluminum wire and you've got the ideal solution for containing pets and keeping out small nuisance animals. Make sure your electric fence charger meets the requirements of your electric fence, refer to your Patriot installation manual for guidance. This will vary depending on the type of fence, the number of fence wires, how much vegetation is growing around the fence and the climate. Remember, if you extend the length of the fence by adding to the fence or subdividing it with temporary fences, you need to make sure your charger is powerful enough. If you use a more powerful charger, make sure you increase the number of ground rods in the ground system. Avoid using different metals in your electric fence. In damp conditions, when an electric current passes through the differing metals, electrolysis will occur. For example, using stainless steel ground rods and an aluminum leadout wire will cause problems. In a short space of time, the aluminium will disintegrate. If possible, keep the wire joints above the soil to improve airflow and reduce electrolysis. Seal the wire joints with thick paint, epoxy or tar to keep moisture away from the joint area. Use identical metals in your electric fence will avoid problems with electrolysis altogether.
