In electric perimeter fencing, the heartbeat is the energizer. the energizer in plain terms is a transmitter that can convert low power to a huge quantity of power to the person touching the wires. the energizer used for this purpose will not allow anyone to be killed as the unit is designed to allow the power to pulsate on/off on a continuous basis. therefore unlike power in the house (where the possibility exists that you could die if experiencing a shock), the electric fence power switches on and off momentarily and therefore is termed a non-lethal electric fence. for any electric perimeter fencing work, contact us today at Lij technology.
