What is a fence charger?
Also known as an “energizer,” “controller,” or “fencer,” a fence charger controls and delivers power to an electrified fence. It is the power supply for your fence, and the heart of the system.
Powers all types of fence
While the ElectroBraid® 2 joule AC low impedance fence charger is specially designed to be used in conjunction with ElectroBraid® fencing, this heavy-duty fence charger can be used on all types of fence, including high-tensile, polywire and polytape.
- 115 volt, 60 cycle
- 2 joule output
- Pulsed output – one-second intervals
- Digital timing
- Fuseless design
- UL Listed
- Made in the USA
The power even pushes past weeds
“Low impedance” chargers have low internal resistance and are able to deliver consistent voltage over very long fencing distances, so you get peace of mind knowing that horses or livestock anywhere along the fence will receive the same correction. Low impedance technology also means that energy can push past weeds or vegetation to keep the fence active or “hot.” Keep in mind, however, that weeds can draw power from the fence and reduce fence efficiency. A voltage tester can help you determine that adequate voltage is on the fence line. Using an ElectroBraid® Digital Electric Fence Tester can help you assess that the proper output voltage is on your fence line.
WARNING: Only use an ElectroBraid® LOW IMPEDANCE energizer that is UL or CSA approved. NEVER use an energizer labeled “WEED BURNER”, “WEED CHOPPER”, or continuous current fencer; they are unsafe and WILL damage ElectroBraid®.
How do I choose the right fence charger for me
When deciding on a fence charger, you need to consider:
- The length of your fence
- The number of strands/wires
- Amount of vegetation growing under the fence
Vegetation and Distance Rating*
No Weeds – 25 miles Light Weeds – 12.5 miles Heavy Weeds – 6 miles * Mileage rating for fences is based on a single strand of wire. Divide the mileage shown by the number of strands in your fence to determine the maximum recommended fence length.
Installing an ElectroBraid® charger
First decide where to locate the ElectroBraid® AC charger. An energizer should be mounted on a wall indoors, away from flammable material and out of reach of children. The next step is to install proper grounding, because your electric fence is only as good as its grounding system.
Why is proper grounding so critical?
Grounding is an essential part of your electric fence system, and the effectiveness of your electric fence and the safety of your animals depends on it. If the ground terminal of the charger is not securely grounded, the path of electric current cannot be completed and the animal will not feel the shock. We recommend using a minimum of three ElectroBraid® copper ground rods spaced at least ten (10) feet apart in a triangular configuration. Look for soil that is wet or moist year round to place your ground rods. Dry, rocky, sandy or frozen soils may present special problems, and more ground rods may be required. You may also want to consider ElectroBraid® sectional ground rod kit for some difficult installation circumstances.
How grounding works
It is important to understand how and why you need an effective ground system. For an electric fence to provide an effective shock, an electric circuit must be completed. That means the electrons passing along the fence must pass through the animal and then return back to the charger. The electrons can return to the charger either by travelling through the ground to the ground rods or through the negative (grounded) strand on your fence, which is connected to the negative terminal on the charger.
A grounded fence strand recommended
We always recommend a negative (grounded) strand on your fence. No matter how dry the soil condition, a negative strand on your fence will deliver a shock to any horse that touches both the negative (grounded) strand and a positive strand of Braid™ at the same timer.
Ground rod placement
Ground rods should be placed at least 25 feet from your fence charger and near the fence line, but at least 50 feet away from any underground piping, cable or other grounding system. A ground rod closer than 50 feet to a waterline (even if the waterline is plastic) may cause signal interference in your home computer, phone, radio or TV. Ground rods closer than 25 feet from the energizer may damage the energizer during electrical storms. Remember to attach clamps BEFORE driving ground rods as the end of a ground rod may mushroom from pounding, making it impossible to slide a clamp over the end.
When you have installed your ground rods, connect them with heavily insulated copper lead-out wire rated for at least 15,000 volts. ElectroBraid® High Voltage Insulated Copper Lead Out Wire are designed for this purpose. Strip a ¾ inch length of the insulating jacket and secure with cable ties for a trouble-free, permanent installation. Secure connecting wires to the ground rods with ElectroBraid® Ground Rod Clamps. After all ground rods are connected, connect one ground rod to the negative terminal on your charger.
Do not confuse or combine ground rods for your house with ground rods required for an electric fence charger. The ground rods used with a fence energizer act as receivers for electron flow. Grounding is one of the most critical elements in any electric fence system. Over 95% of all electric fence problems result from poor grounding.
WARNING: Never use regular house wire or ElectroBraid ® for your electrical connections. Only use high voltage, heavily insulated, copper lead-out wire, copper clad ground rods and brass ground rod clamps.
How to wire your charger/energizer
You can now connect your charger to the ElectroBraid®. Run a length of ElectroBraid® High Voltage Insulated Copper Lead Out Wire from the positive terminal on your ElectroBraid® charger to the top strand of Braid™. Feed the copper wire into an ElectroBraid® Poly Braid Splicer, which is fastened to the Strand.
NOTE: For easier troubleshooting, you can use an extra ElectroBraid® Poly Braid Splicer to connect your electrical components. If you want to disconnect the electrical from a strand you will not have to use the tensioning device to hold the tension. NOTE: Use of cable ties will prevent lead-out wire from breaking due to vibration. After the tension has been taken off the line you are electrifying, feed the copper wire from the charger into the poly Braid splicer. While you have the poly Braid splicer loose, cut and insert another piece of copper lead-out wire that will be used to jump the electricity to the third strand. Repeat for the fourth strand (this technique will allow you to easily disconnect the lower line(s) in case of heavy accumulation of snow fall which may cause the fence to short). Before inserting, pre-measure the proper length of the jumper wire and strip away 1 inch of insulation so the copper in the lead-out wire is exposed to ensure a good connection. After all leads have been connected, re-tighten the poly Braid splicer, release the ratchet, and attach cable ties. Bury all wiring 8 to 10 inches deep. NOTE: We recommend you thread all positive wiring through a piece of ¾ inch conduit (flexible Poly water pipe) to avoid abrasion and to prevent shorting between negative and positive wires. Bury the pipe 8 to 10 inches deep. Strap the ends of the pipe to the gate posts with the ends turned down to prevent rain and dirt from filling the pipe.
How do I wire for areas of high snowfall
Heavy, wet snow can short electric fencing. To prevent this, you can wire fences in areas prone to snow accumulation as illustrated below. ElectroBraid® cut-off switches can be installed to allow you to progressively turn on and off the bottom strands with the changing depth of snow. Wire your fence energizer as shown in the diagram.
The importance of routine fence testing
After installing your fence charger, you should routinely check and test your fence line. Insulators should be kept free of dirt, dust and cobwebs. The fence line should also be clear of weeds. Weeds can draw power from the fence, causing it to lose efficiency. Check for tree limbs and other debris that may be touching the fence. A voltage tester can help you determine that adequate voltage is on the fence line. Using an ElectroBraid® Digital Electric Fence Tester can help you assess that the proper output voltage is on your fence line.
ElectroBraid® Braid will not rust, rot, lose strength due to sunlight or weathering, break when installed as a permanent fence or prove defective in workmanship or material. Any reel of ElectroBraid® Braid that is defective will be replaced at no charge to the purchaser. This warranty is in effect for 25 years from the date of purchase.

Most Recent Customer Reviews
Review RateReview is for the 4 Joule ElectroBraid chargerI had purchased the 4 joule ElectroBraid charger and rated it at I believe 3 stars due to no apparent improvement in the ability to push through low to medium weeds. I found that my voltmeter was defective and reading about 4,000 volts regardless of where I tested. I then used a different meter and found that the 4 joule did indeed push 6,000 volts through low - medium weeds. To verify I used yet a THIRD meter which validated the 6,000 volts. The ElectroBraid 4 joule charger is great AND the Zareba team is FANTASTIC to work with.
Review Ratevery good and priced rightjust installed on my fence and i am getting full voltage even with the weeds touching the wire

All About Fence Chargers
Chargers are the heart of the fence system, providing the source for the electric current that flows through the fence wire.
The size of charger needed is dependent upon your fencing needs. These needs are determined by three main factors: the length of the fence (number of wires), the power source (AC, DC or Solar), and the type of animal being contained or excluded.
See our comparison charts of our fence chargers to help you determine which is best for your needs.
Types of Chargers
There are three main types of chargers: AC-Powered, Battery-Operated and Solar-Powered. The source of power for the charger to function determines the type of charger you will be using. Each type of charger has specific situations in which it is most desirable to use.
Selecting the right fence charger with adequate power for your enclosure is critical to keeping your animals safe.
Choosing the Right Fence Charger
The right fence charger is the heart of your electric fence system. Finding the best-matched charger for your fence is imperative to successfully contain/exclude animals. The experts at Zareba® Systems explain a simple process to ensure you buy the right fence charger to meet your needs.
Installation and Location
Every Zareba® Systems fence charger comes with a detailed installation manual. In addition, individual components include “how-to” instructions to assist in your fence system assembly.
Lightning and Power Surge Protection
Lightning is often the cause of fence charger failure. When lightning strikes the fence, the sudden power surge can travel down the fence wire and damage the fence charger.
A variety of properly installed products can prevent or limit lightning damage.
FAQs about Chargers
Q: What factors should I consider when purchasing a fence charger?
A: The power source (AC, Battery or Solar Powered), energy output (in joules), the type of animal being controlled, the length of the fence (more wires need more power) and the amount of vegetation growing near the fence should be considered when you are selecting your fence charger.
Q: What does Low Impedance mean? I see it on chargers in stores and on websites.
A: Low impedance chargers increase the joules (energy) on a fence line if weeds or other vegetation touch the fence. Low impedance chargers are ideal for long, multi-strand poly wire, tape, rope or high tensile fence systems. Low impedance chargers are recommended for most applications and can be operated by AC, DC or Solar Power.
The other type of charger, known as a solid state charger, is usually used to control short-haired livestock, small animals, and pets where only moderate weed conditions exist. These chargers deliver a medium-amperage shock and can be operated by AC or DC.
Q: Why does my fence charger make clicking noises?
A: Most fence chargers have a pulsed output. Every time it “clicks,” it is releasing energy to the fence that has been stepped up or increased through a capacitor and a transformer. This release of energy makes noise. Not all chargers make the clicking noise. The noise is designed for the owner of the charger and serves no functional purpose.
