CHOOSING THE RIGHT ENERGISER
In order to simplify the choice of an energiser in any particular circumstance, consider all the following factors.
VEGETATION (WEEDS ETC)
The decisive role in the selection of an energiser is determined by the effect
of vegetation at the fence. The high output energy of the PATURA energisers is used primarily to destroy heavy vegetation at the fence and, despite this vegetation, to maintain a high voltage level at the fence. These are the various vegetation conditions:
FENCE LENGTH
After the vegetation, the length of the fence plays the next most important role in the selection of equipment. By fence length we mean not the total length of the individual wires added together,
but simply the length of the actual
fence itself. Multi-wire fences carry the current better than single strand ones, providing that the wires are connected to each other at regular intervals.
ANIMAL TYPE
The type of animal plays an important role in the selection. With animals that are dif cult to contain, such as wild animals, sheep, goats and fowl, powerful equipment should be used. With more easily contained animals, such as cattle, horses, pigs and domestic animals, less powerful equipment is needed for the equivalent length of fencing.
For recommended maximum fence length please refer to the tables for the particular energisers.
THE POWER SOURCE
Various power sources are available for powering energisers:
• 230 volts AC from the power outlet
• 12 volts DC from a rechargeable battery
• 12 volts DC from solar cells + battery
• 9 volts DC from non-rechargeable batteries
Refer to charts on pages 274- 279 for detail relating to
the distances energisers will power.
No vegetation –
no contact between the vegetation and the fence wire
Normal vegetation –
the vegetation is often touching the wire
Heavy vegetation –
the wire runs completely in vegetation
Electrical cross connection of Typically posts are the wires - approx. every 200 m spaced 3-5 m apart

Animals that are easy to contain
There are many reasons for choosing an energiser with a mains connection, should such a connection be available: the acquisition price of the energiser
is relatively low, the energy costs are extremely low, and the ease of operation is very high. If there is no mains supply available, then the next best alternative is equipment with a 12 volt battery connection. The energy costs are
still justi able, but the maintenance requirement for the recharging of the batteries is nonetheless considerable. In
Animals that are dif cult to contain
order to minimise this requirement – at least in the spring to autumn period – we recommend the use of solar panels, especially so with the more powerful 12 volt energisers.
The most expensive alternative for powering energisers is the use of 9 volt non-rechargeable dry batteries, which also have to be disposed as special waste when exhausted. The advantage with these energisers is that they are easy to use, but their low power is a disadvantage.
