There are commercially available electrifiers that are too powerful!
Beyond 2 Joules output (for long and large installations), they “burn” the polyethylene plastic and stainless steel wires bi-polar tape.
The energizer must be LOW IMPEDANCE (those for breeding are all today).
A fence tester is useful for checking that 4000 volts is maintained throughout the fence line. Fence testers are also available in our online store.
Examples of installation length for a mains-powered energizer:
2 km/6500 ft maximum total tape length:
Maximum output voltage: 5400 Volt
Maximum pulse energy: 0.10 Joule
4 km/13120 ft maximum total tape length:
Maximum output voltage: 6200 Volt
Maximum pulse energy: 0.30 Joule
9 km/29500 ft maximum total tape length:
Maximum output voltage: 7700 Volt
Maximum pulse energy: 0.6 Joule
For an installation with a solar energizer, it will need to be more powerful than the mains-powered one.
If you are adding a bi-polar fence to a traditional electrical system powered, you will need a second energizer. Your existing energizer cannot supply two different systems at the same time (traditional and bi-polar).
For your fence to work properly, each fence system must have its own power supply: one energizer per system.
HorseGuard does not sell electric chargers (energizer) in Canada. They can be purchased at any agricultural cooperative.
Here is some useful information to inform the selection process:
The energizer must be LOW IMPEDANCE and powerful enough to ensure a minimum of 4000 volts permanently on the fence.
The low impedance enables continued performance in the presence of a point of contact.
The different types of energizers
Mains energizers are the best choice when access to stable power is present.
Solar powered portable energizers with internal batteries are a self-sufficient option, and a logical choice for remote areas.
Portable battery powered electrifiers generally operate at 12 volts, with a rechargeable battery that will be charged and discharged regularly.
Connected energizers with back-up batteries are the practical choice in areas where supplied power is not reliable.
