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.
