Fence energizers are the heart of the fence system, providing the source for the electric current that flows through the fence wire. Fence energizers vary by amount of current they output and their power source.
The size of fence energizer needed is dependent upon your fencing needs. These needs are determined by three main factors: the length of the fence, number of wires, the power source (AC, DC or Solar), and the type of animal being contained or excluded.
See our comparison charts of our electric fence controllers to help you determine which is best for your needs.
