Gallagher 7.7-Joule Plug-In M1100 Electric Fence Energizer

The Gallagher M1100 Mains Fence Energizer is a robust, high-output AC-powered unit built for large pastures and diverse livestock containment needs that require consistent, dependable fence performance across substantial acreage. Delivering 11 stored joules with 7.7 joules of energy output, the M1100 is capable of powering up to 36 miles of typical fence line covering approximately 280 acres under good conditions with proper grounding and minimal vegetation contact. A quickscan output voltage bar graph combined with a digital output reading gives you an at-a-glance and precise view of fence voltage without needing a separate tester, while a green LED indicator provides immediate confirmation that the unit is operating normally. Split bolt terminals make for secure, straightforward connections during installation, and a modular internal design simplifies servicing and minimizes downtime if maintenance is ever needed. A durable outer casing and built-in lightning protection keep the unit running reliably through harsh environmental conditions and the electrical surge risks that come with year-round farm operation. The M1100 operates on a standard 110-volt AC power source, making it a practical choice for any farm or ranch with access to mains electricity. Backed by Gallagher's 3-year manufacturer's warranty and U.S.-based customer support, the M1100 is a dependable, serviceable energizer built for long-term performance on large operations.
