Frequently Asked Questions
How does an electric fence energizer work?
A fence energizer converts power (from a battery or mains) into a high-voltage pulse that travels through the fence wire. When an animal touches the wire, it receives a brief but memorable shock that encourages it to avoid the fence.
What kind of battery is best for an electric fence?
For battery-powered energizers like the MB150, a 12V deep cycle battery is recommended. These hold a steady charge over time and are designed for long-term use.
What is a fence energizer?
A fence energizer is the power source of an electric fence system. It delivers controlled electrical pulses that maintain the integrity of the fence line and prevent escapes or intrusions.
How to test a fence energizer?
To test a fence energizer, use a fence tester or voltmeter to check the voltage at multiple points along the fence line. A good reading confirms proper operation, while low voltage may indicate grounding issues or line faults.
