The Zareba 10 Mile AC Low Impedance Electric Fence Charger is used to control small livestock pets and poultry as well as repel nuisance animals in locations that have access to AC power. This charger powers up to 10 miles of fence and works in heavy weed conditions. Low impedance electric fence chargers have low internal resistance. This allows for increased joules on the fence line; which means that energy can push passed weeds or vegetation to keep the fence hot.
