Which unit for which fence?

The type of animal is significant in choosing the correct unit - high performance electric fencing energisers should, for instance, be used with hard to control animals such as bulls, sheep, goats and poultry.

With easily controlled animals such as cattle, horses, pigs or domestic animals and the same fence length, units with lower output can be used.

The correct choice of electric fencing energiser therefore depends on the specific type of animal, the length of the electric fence and the plant growth under the fence. Therefore select an electric fencing energiser with adequate discharge energy and adequately high voltage during animal contact.

  • Units with a discharge energy of up to 1.00 Joule are suited for short haired and easily controlled animals and short electric fences with no or hardly any greenery.
  • Units with a discharge energy of up to 3.00 Joule are suited for fairly hard to control animals and average fencing systems with normal greenery.
  • Units with a discharge energy of up to 5.00 Joule are suited for long haired and hard to control animals, for keeping wild animals out and for long fencing systems with heavy plant growth.

It is also important to ensure adequate voltage (at least 2 000 Volt) to overcome the resistance of the animal’s hair and hide. The voltage during animal contact (voltage with 500 Ohm load) is always important here, not the open circuit voltage.

A minimum voltage of 3 000 - 4 000 Volt is recommended for long haired and hard to control animals, whilst a lower value ( 2 000 – 2 500 Volt ) suffices for short haired and easily controlled animals.
