Mains energisers are ideal for permanent fencing. The devices are cost effective to run and generally more powerful than battery powered models. In this category you will find a wide range of mains energisers, here we will discuss what to take in consideration when selecting your device.

Is a mains energiser the solution for you?

When selecting a fence charger, it is important to have a clear view of your situation. A mains energiser is the perfect solution for permanent fencing as it is connected to your mains energy supply in your barn. Even though all mains energisers have a IPX4 rating, it is recommended to put up your energiser somewhere dry. In most situations we see the device being put up in a shed where it is protected from environmental factors. If you are in need of a high power fence charger, a mains electric fence energiser is in this case recommended. Our high end mains energisers have a higher stored energy(J) capacity compared to battery and solar energisers. The stored energy is an indication of the shock produced by the energiser.

There are different types of mains energisers. Depending on the features you are looking for, we have the right device for your fence. The most common fencers operate solely with mains power. These energisers have to be connected to a socket to charge your fence. Beside these models, we offer dual powered energisers. These models are both mains and battery powered. These models are mostly used when multiple fences need to be powered and there is not always a mains plug nearby.

Location and connection

Mains powered electric fence energisers should be put-up close to a mains plug. And for the mains energiser to perform at its best it should be located near the fence. However it is possible to connect the device with a lead out cable to a paddock a bit further from the shed. Please be aware that, in this case, your energiser should be a bit less powerful.Compared to solar and battery energisers, mains energisers have a good cost to performance ratio. A mains energiser often has a higher performance when we look at the maximum output voltage and maximum output joules. Where the devices are beaten by batteries and solar energisers is its mobility. If you do not have a dual use device, these models need to be installed near a mains plug. This limits the mobility of the energisers. To get the best performance from your mains fence charger, it is important to have it properly installed. When installing the charger, it is important to use at least the amount of recommended earth stakes. Using fewer will result in a performance dip of the energiser. The fence connected to your device could also function less, when a lot of vegetation is touching it or a branch is touching the fence. Use electric fence testers to check if your fence is performing optimally.
