Mains energisers are always the most reliable choice in case there is a power outlet available. They are an alternative to battery-powered fence energisers which can be used independently of mains power. They are characterized by high performance and provide the important herding security. The electrical energy is released in the form of a short shock pulse if the animal comes into contact with the fence. The energiser is connected to the mains and transmits the supplied energy to the electric fence system, guaranteeing a continuous power supply. Mains energisers are easy to handle and offer a high level of operating comfort.
