An electric fence Energizer is a device that provides a safe but effective shock via a pulsed high voltage current to the electric fence wires. The energizer can be powered by either 220VAC mains power or 12VDC battery backup power. The energizer is connected to the electric fence wires via specialized double insulated HT cable. All energizers have to be manufactured and installed to comply with a published national standard (SANS 60335-2-76) to ensure the safety of the population. Energizers have different power outputs dependant on application. Energizers are used to power domestic, commercial and industrial electric fence sites but also have application in a multitude of game fencing for protection and containment of a variety of animals.
