Thunderbird MB-375 35km Battery & Mains Electric Fence Energiser
The Thunderbird MB-375 is a dual-power electric fence energiser. It runs from either a 12V battery or 240V mains power. This battery mains energiser energises up to 35km of fence. It suits large rural properties and intensive livestock operations. The dual power input means you can switch power sources at any time.
The MB-375 delivers a powerful output pulse that deters cattle, horses, sheep, and other livestock. It maintains an effective charge even on long fence runs.
