Field Guardian Warden (FGB-100) Low Impedance Electric Fence Charger, UL Listed, 1 Joule
The FGB-100 (a match for the Power Wizard 1000B) is a strong 1 to 1.4 joule electric fence charger. So it can effectively contain horses in medium to large pastures. Regarding batteries, a 60 amp hour battery will keep the FGB-100 running for 2 weeks; and a 110 amp-hour battery will keep it running for a month. We do not offer large “deep cycle” batteries (the kind needed) on this website, but they can be obtained at www.ebatteriestogo.com or at almost any local store that sells boat or golf cart batteries. Voltage data: The FGB-100 electric fence charger will keep 4,000 volts on the line so long as the weed burden is minor (providing nothing more than a 500-ohm path to the ground), and it will keep some 2,600 volts on the line (more than enough to reliably shock horses) even when challenged by a large weed burden providing a 100-ohm path to the ground. Joule range: The FGB-100 yields a 1-joule pulse on a 500-ohm circuit and a 1.4-joule pulse on a 100-ohm circuit. (For more about joules see Charger Safety, Horse Fences, and Joules). Other animals: The FGB-100 is useful for containing livestock (including cattle, pigs, sheep, and goats), and for keeping out predators (including foxes, coyotes, wolves, javelinas, and feral pigs). General data: The FGB-100 has an all-weather case, built-in lightning protection, and advanced engineering that provides peak output under difficult conditions. It also comes with a flashing light that shows when the unit and its immediate fence connections are working properly, installation instructions, and a 1-year warranty against manufacturing defects and lightning damage. Battery not included.
