Thunderbird M300 240V Mains Fence Energiser

The Thunderbird M300 is an Australian-made electric fence energiser designed to power up to 30km of clean fencing under ideal conditions. Its dependable 240V mains operation makes it suitable for permanent livestock fencing on farms and rural properties with access to a reliable power supply.

With 3.0 joules of stored energy, the M300 provides substantially more capacity than smaller property energisers. It is designed for farmers who need dependable continuous power across longer fence runs or more demanding livestock-control systems.

Reliable Power for Farm Electric Fencing

Mains-powered energisers provide consistent fence performance without relying on battery condition or available sunlight. This makes the Thunderbird M300 suitable for permanent electric fences installed near sheds, yards or other buildings with access to 240V power.

The energiser can be used for cattle, sheep, horses and other livestock when matched to an appropriately designed fence and earthing system.

Capacity for Longer and More Demanding Fences

The M300 delivers 3.0 stored joules and maintains approximately 5.7kV against a 500-ohm load. This provides useful capacity for longer fences and systems exposed to moderate vegetation pressure

The advertised 30km distance is based on ideal conditions. The number of live wires, underground cable, vegetation, damaged insulators and poor connections can all reduce the effective operating distance.

Safe Mains-Powered Installation

The Thunderbird M300 must be installed in a dry, protected and well-ventilated location near a suitable 240V power outlet. Follow the supplied installation instructions and do not expose the power connection to rain or moisture.

Use suitable double-insulated electric fence cable between the energiser, fence and earth system. Keep the electric fence earth system away from household electrical earths, water pipes and other utility earth systems.

Is the Thunderbird M300 Right for Your Fence?

The M300 is a practical choice for medium-sized farms and permanent livestock fences that require more capacity than a small mains energiser. It is suitable for longer fence runs and systems that may experience a moderate vegetation load.

For very extensive multiwire systems, severe vegetation pressure or future fence expansion, consider selecting an energiser with additional stored energy. Correct earthing remains essential regardless of the energiser’s maximum distance rating
