Gallagher 0.48 J 15-Mile M120 Mains Fence Energizer

The Gallagher M120 Mains Fence Energizer is a dependable, easy-to-use AC-powered unit built for small pasture applications where straightforward installation and reliable everyday performance matter most. Delivering 1.2 stored joules with 0.48 joules of energy output, the M120 is capable of powering up to 15 miles of clean fence under good conditions with proper grounding and minimal vegetation contact or up to 6 miles on a typical fence with moderate vegetation load making it a practical choice for small livestock operations, crop protection, and predator deterrence. Simple fence terminals and a hassle-free mounting system make installation approachable for first-time and experienced users alike, with no complicated wiring or hardware required. A power-on indicator light lets you confirm at a glance that the unit is live and operating normally without the need for a separate tester. A tough outer casing and built-in lightning diverter protect the unit from physical wear and electrical surge damage, and UL approval adds an additional layer of confidence in the unit's electrical safety standards for permanent installations. Backed by Gallagher's 3-year manufacturer's warranty and U.S.-based customer support, the M120 is a no-fuss, reliable energizer for small farms, hobby operations, and anyone getting started with AC-powered electric fencing.
