Defender Electric Fence Energisers

Defender Electric Fence Energisers, in our experience, are the most suitable and reliable electric fence energisers for equine use and can be run from either a battery or the mains.

To work effectively, the power output from the energiser should be a minimum of 3000 volts. For safety, the power through the fence should be 5-8,000 volts. The optimum type of shock to safely contain horses should be a very short but extremely high voltage pulse – similar to a bee sting.

We stock the following energisers;

  • D5 0.5 Joule
  • D10 1 Joule
  • D20 2 Joule
  • D30 3 Joule
  • D50 5 Joule
