The Stafix X12i Unigizer is a high-powered electric fence energizer engineered for large-scale agricultural or game fencing. Delivering a maximum output of 12 Joules and storing up to 16 Joules of energy, it is ideal for powering long, multi-wire fences—up to 65 km in length—across challenging terrain and vegetation. The X12i operates from mains power, a 12V battery, or solar, offering exceptional flexibility for both on-grid and remote installations. It features Cyclic Wave™ technology to maintain clean, consistent energy pulses along the fence line and includes bi-polar operation for superior performance in poor soil conditions. A backlit LCD screen provides real-time diagnostics of output voltage, earth condition, and battery level, while additional features like a day/night sensor, earth monitoring, and remote control capability make it user-friendly and efficient. Rugged and reliable, the X12i is built for tough farming environments and is trusted globally for serious perimeter security and livestock control.
