One of the most important - components of an electric fence is the electric fence energiser. It provides the electric pasture fence or electric pet fence with electricity and supports the safety of your animals. You need to consider the type of fence, the requirements for it, the type of animals that need to be guarded and the budget.

An electric pulse is released by the energiser via the connection cable and gets further transported via the conductor material like tape or polywires. The fencing material ensures that the entire fence is supplied with sufficient electrical voltage. If an animal - which is enclosed by the fence or tries to get inside the fence - touches the fence, it will receive a brief but strong shock. This happens because it closes the previously open electric circuit by touching it. The shock is meant as a deterrent, whereas animals usually "learn" from the electric shocks and do not attempt to escape or destroy the fence again. The electricity flows through the animal's body into the ground and via the ground rod back to the energiser.

No, because fences and chargers are tested for their safety and used in a way that ensures risk-free functioning if used correctly. The harmless electric impulse is short and intensive, yet effective. As soon as the animal moves back from the fence and the contact to the fence is broken, it will not receive any further shocks. When erecting the fence, it is important to make sure that connectors (instead of tying knots) are used for an appropriate connection of the conductors and to ensure that the fence functions properly.

Here we differentiate between stored energy (in the energiser) and pulse energy (the fence pulses). As the name already suggests, the latter is responsible for the actual output power, the strength of the pulses. The device is supplied with energy, whereas the energy balance depends on the resistance measured in ohms. The joule rate indicates how strong the shock pulse is, which the animals are exposed to when touching the fence. Too high a number is dangerous for small animals, whilst large animals won't sufficiently notice too small a pulse strength or could get used to it.

The voltage is just as important as the pulse strength. Both, the open circuit voltage as well as the output voltage can be found in the product specifications. Several factors should be considered when choosing the voltage strength of the energiser: The animal species What are the soil and vegetation like? Length: how big is the area that needs to be fenced and how long is the fence to be? How complex is the electric fence？ Which conductor material has been chosen? Power supply: Which kind of power supply is used (fixed voltage, battery, solar technology)?
