Gallagher 4.9 J 90-Mile M800 Mains Fence Energizer

The Gallagher M800 Mains Fence Energizer is a high-output AC-powered unit built for small to medium pasture operations that need a step up in fence coverage and reliable all-season performance. Delivering 8.0 stored joules with 4.9 joules of energy output, the M800 is capable of powering up to 90 miles of clean fence covering approximately 520 acres under good conditions with proper grounding and minimal vegetation contact or up to 30 miles covering approximately 200 acres on a typical fence with moderate vegetation load. Simple plug-and-play installation and keyhole mounting points make it easy to secure the unit to a wall, barn, or other flat surface without complicated wiring or hardware. A tough outer casing and integrated lightning protection keep the unit running reliably through harsh weather and the electrical surge risks that come with year-round outdoor operation. 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 M800 is a dependable, low-maintenance energizer for operations that need proven performance across more ground without stepping up to a commercial-grade unit.
