Main Energizers


Main Range / Main Energizer

A main powered energizer is the most cost-effective, reliable way to power a permanent electric Fence. Powers from 200-630 km (275-850 acres) of fence.

Speedrite mains powered energizers are high performing, powerful units designed for extensive electric fence systems.

Features explained:

  • Load response feature – Controls energizer output to match conditions, providing maximum fence voltage for effective stock control.
  • Low Interference - Cyclic WaveTM technology delivers outstanding fence performance and helps to minimize electromagnetic interference in line with international EMC standards.
  • Large Terminals – Mounted on the front of the energizer casing for convenience, these large terminals are easily adjusted and accept up to two fence wires. The slotted terminals make inserting wires and getting a good connection easy.
  • Cyclic WaveTM Technology – Provides a cleaner, more powerful pulse, maximizing the energy that travels down the fence for optimal stock control.
  • Bi-Polar Technology – Enables the user to power a fence system to perform exceptionally well in dry, low conductive soil.
  • Indicator Lights (Voltage) – Easy to read light bar display provides an instant measure of the energizer output voltage for quick fence diagnostics. The LED display shows red when heavily loaded.
