What features should I look for when choosing the best mains electric fence energiser for my needs?

When choosing the best mains electric fence energiser for your needs, there are several features that you should consider. The first thing to consider is the power output of the energiser. The power output should be sufficient to provide the necessary electric shock to the fence wire without causing harm to animals or people. The second thing to consider is the voltage of the energiser. A higher voltage energiser will provide a stronger electric shock and is more suitable for larger areas or more challenging terrain.

Another important feature to look for is the type of energiser. There are two types of energisers – pulse and continuous. Pulse energisers send short, intermittent bursts of electricity to the fence wire, while continuous energisers provide a constant flow of electricity. Pulse energisers are more energy-efficient, while continuous energisers are more effective at deterring animals.

You should also consider the size of the area that needs to be fenced, as well as the type of animals you want to keep in or out. Some energisers are designed for smaller areas, while others are suitable for larger properties. Additionally, some energisers are designed to work with specific types of animals, such as horses or cattle.

Lastly, it is important to consider the quality and durability of the energiser. You want to choose an energiser that is built to last and can withstand harsh weather conditions. Look for energisers that are made of high-quality materials and come with a warranty for added peace of mind.

What is the maximum distance a mains electric fence energiser can cover?

The maximum distance a mains electric fence energizer can cover depends on several factors, such as the power of the energizer, the type of wire used, and the condition of the fence. Generally, a mains-powered energizer can cover longer distances than a battery-powered one. However, the maximum coverage area varies between different brands and models.

In most cases, a mains electric fence energizer can cover up to 100 miles or more, depending on the power output. However, it's important to note that the voltage and current will decrease as the distance from the energizer increases. This means that the fence may not be as effective at deterring animals at the far end of the fence.

It's also important to consider the type of wire used and the condition of the fence. A poorly maintained fence or low-quality wire can decrease the effectiveness of the energizer and reduce the maximum distance it can cover.

Overall, it's best to consult with the manufacturer or a professional electric fence installer to determine the maximum distance a specific energizer can cover based on your specific needs and circumstances.

What is the price range for the best mains electric fence energisers?

The price range for the best mains electric fence energisers can vary depending on the features, power output, and brand. Generally, the most reliable and efficient mains electric fence energisers can range from $100 to $500. However, there are some high-end models that cost more than $500, with advanced features such as remote monitoring, lightning protection, and power surge protection. On the other hand, there are also some budget-friendly options that cost less than $100, but they may not offer the same level of performance and durability as the more expensive models. When choosing an electric fence energiser, it's important to consider your specific needs, budget, and the type of animals you'll be containing. It's also advisable to invest in a quality energiser from a reputable brand to ensure safety and longevity.

What is the voltage output of the best mains electric fence energisers?

The voltage output of the best mains electric fence energisers can vary depending on the specific model and brand. However, in general, the voltage output can range from 5,000 to 10,000 volts.
