Energizers

The energizer is what makes an electric fence work. An undersized or low-grade unit gives a weak shock that intruders quickly learn to ignore.

Choose an energizer rated for your total wire length, with alarm output if you want a siren or GSM alert, and a battery backup option for power cuts. Nerpax supplies genuine energizers, helps you size them for your perimeter, and offers installation and commissioning with proper earthing. We deliver across all the counties we serve.
