Electric Fence Energizer

Electric fences are supplied power by an electric fence energizer or electric fence charger. The advantage to an electric fence is that it requires less labor to erect because there is less material needed to hold an animal with it. Anelectric fence drawing electric fence uses fewer materials because this sort of fence relies on the shock of electricity to maintain the respect of the animals for the fence line. Again, this shock is supplied by an electric fence energizer or electric fence charger.

Electric Fence Charger

Less sophisticated alternating current, or AC, fence chargers relied on a mechanically-driven switch and a transformer to create electrical pulses. However, these pulses were unpredictable, and would experience a decrease in power when “leakage” or grounding of the fence occurred. This problem was solved when the solid state circuit was used somewhat, but still experienced problems in control of voltage.

My family used a “weed burner” electric fence charger when I was a teenager. These electric fence energizers were marketed on the premise that they would cut weeds down that touched the fencing. However, this seemed problematic at best. It was my experience that they would cut some of the weeds, however, they would become overwhelmed by a huge growth of weeds. My dad seemed to have the same opinion of them, so, he employed his workforce (me) to solve this problem. Despite the fact that these models continue to be offered, they have not remained very popular.

The more modern electric fence chargers or energizers have solved many problems that earlier models experienced. They have a more narrow pulse that is more powerful and experiences less grounding. Newer chargers may be powered by large lead-acid batteries or sometimes by a small battery which is charged by a solar panel. Some electric fence energizers can use either batteries or other power sources.
