Electric Fence Controller

Gallagher makes a large specialized line of electric fence controllers. One model, the Gallagher KM2 electric fence controller was found to be adequate over a various range of fencing conditions. Usually, growth from plants didn’t affect the controller’s performance in most conditions.

The peak voltage output on a 3.3 mile single wire fence did vary from 1630 volts on an well-insulated, grass-free, dry fence to as low as 1100 volts on an uninsulated, grass-covered, wet fence. This is impressive.  The unit’s output was well above the 700 volts minimum voltage recommended for short-haired animals. However, it was lower than the 2000 volts minimum required for long-haired animals.

The Gallagher KM2 was tested in various climatic conditions. It was found to be quite suitable for cold weather use with shorter feeding fences. The peak voltage output at -35°C the same length single wire fence was about 1610 volts, but only two percent higher than its normal output at room temperature.

Electric Fence Chargers

These type of electric fence chargers are best used for wide ranges of fencing conditions. Amazingly, wire insulators were unnecessary for most fences and plant growth didn’t really affect the charger performance in most conditions.

The peak voltage 3.3 mile fence with a single wire actually varied from 5210 volts on an well-insulated and grass free, dry fence, all the way to 3690 volts on an uninsulated and grass grown, wet fence. However the output was well above the 2000 volt minimum recommended for long haired animals.

This Gallagher model was found to be quite suitable for cold weather use and on feeding fences. The peak voltage output was at -35°C for a 3.3. mile single wire fence; around 5240 volts, which is 1% higher than its normal output at room temperature.

Like with most electric fence chargers from Gallagher, no durability problems took place during the testing of this model.
