The electrical pulse

The sheep and goat collar’s power unit has a stored power of 0.1 Joule and max 3 kV. The cattle collar’s power unit has a stored power of 0.2 Joule and max 3 kV. In comparison, a conventional energiser may not exceed a 5 Joule output rating, according to EU standards.*

All our collars are tested to make sure that the electric pulse is at least 1.5 kV. The pulse must be felt in order for the system to work, as this makes the system predictable to the animal. Moisture, and the substance of the animal’s fur may impact the animal’s experience of the electric pulse. Nofence has documented that effective containment can be achieved when the electric pulse is between 1 and 3 kV. Thus, not too strong, but not too weak.

!People with heart diseases or a Pacemaker should avoid receiving a pulse from the collar.

*So-called “intelligent” electric fence devices can have up to 15 Joules of stored energy.
