The Powerfields PF-AD-50C is a low impedance fence energizer designed for electric fencing systems, capable of covering up to 30 acres. It operates using either a 110V AC power source or a 12V DC battery, offering versatile power options for temporary, portable, or permanent installations. This energizer delivers an output of 0.5 joules and a stored energy of 0.7 joules, with an open line voltage of 8,200V and 3,300V at 500 ohms. Its low impedance technology allows it to maintain effective shock through vegetation and varying fence conditions. Constructed with a tough, impact-resistant ABS plastic case, it includes an AC adapter and battery connector leads, alongside a pulsing power indicator. It is suitable for containing various livestock such as horses, cattle, pigs, sheep, and goats. The unit is backed by a 3-year manufacturer's warranty, which covers protection against remote, indirect lightning strikes.
