Its patented Cyclic Wave pulse technology produces an electrical waveform similar to an ocean swell – the pulses rise and then drop away smoothly to deliver optimal power to the fence. 

  • Energiser automatically senses the vegetation load on the fence, and adjusts output to compensate 
  • Low or high power options – use low power for shorter electric fence runs or more sensitive stock 
  • LED display shows voltage and fence load 
  • Slotted wire terminals provide easy wire connection 
  • Comprehensive instructions included


The SPE Remote Ready range of fence energisers is designed to work with Speedrite’s Remote Fault Finder, offering a wealth of fault-finding technology as well as the ability to switch the energiser off from any location – essential when carrying out maintenance or repairs on large or remote electric fences.
