【Powerful Pulse Output for Safe & Effective Protection】It delivers 12KV voltage and 4.0 Joules of output energy, with an effective working distance of up to 15miles under vegetation-free conditions.This design reliably deters cattle, horses, sheep, chickens and dogs from hitting the fence and prevents intrusions by wild animals like wolves, foxes, raccoons and skunks.The pulse duration is only 100 microseconds, which causes only a brief numbing sensation and does not inflict harm on animals or humans. 【LED Display & Indicators for Intuitive Status Check】Equipped with a real-time voltage display screen, it allows you to easily monitor the current power supply status.The POWER indicator lights up when the power is on, and the RUN indicator flashes to signal normal high-voltage pulse operation. 【Effortless Installation & Clearly Labeled Terminals】This controller includes 2 standard terminals: a ground terminal for the independent grounding system and an output terminal for fence connection. With the included detailed manual, installation takes just 10+ minutes—no professional experience needed! 【Strong Environmental Adaptability & Wide Use】With IP65 waterproof protection and -20℃~+60℃ (-4℉~+140℉) operating temperature, it maintains stable performance in rain and snow. Suitable for farms, pastures, gardens and poultry houses, and using a waterproof box can prolong its service life. 【Strong Pulse Output for Safe, Effective Protection】Boasting 12KV voltage, 4.0 Joules of output energy, and a 10KM effective working distance (no vegetation), this device effectively deters livestock and repels wild intruders. Its 100-microsecond pulse ensures a temporary numbing feeling without harming humans or animals. 15 MilesElectric Fence Charger, 4J Energy Output 12KV Output Voltage,AC DC Electric Fence Energizer with LED Display for Preventing Wild Animals Intruding Great for Gardens,Poultry
