Kube 4000 Energizer
The Kube 4000 plug-in unit is economic and wide-impedance. That means it produces unusually high pulse outputs in fences over dry soils. It performs better than standard low-impedance units during dry/snowy seasons and on fences for deer, poultry and goats.
It's proven, over the past 5 years, to offer reliability and excellent value.

- 3 miles of 3 strand cattle fence
- 1 mile of 5-7 strand sheep fence
- 15 rolls of 164' sheep/goat nets and 7 rolls of 164' PoultryNet
- Requires a grounding system. Inadequate grounding is the most common failure in an electric fence system. We recommend 6 ft. of grounding for this energizer, included in the kit.
- 2.30 released joules
- 2.30 joules in moist soils
- 1.24 joules in dry soils
- Pulses per minute: 40
- 110V draw is 4.5 watt per hour
- Impedance type: wide – pulse type
- Input: AC only
- 6' cord
- Modular. Very easy to repair.
- Connect insulated cable (stripped back 1 - 2" on ends) to the fence terminal on energizer, run the cable to the fence line and connect.
- Then run a second length of cable from the ground terminal (with ends stripped again) on the energizer to the ground rod.
- Secure to ground rod with a clamp.
- Plug the energizer directly into an outlet and test fence. Do not use an extension cord as it may cause a decrease in voltage and expose the unit to the elements.
- Unit indicator light should flash and a tic-tac sound will be heard. If the indicator light doesn't flash, then the unit should be serviced.
To Reduce Risk & Liability
- Never place your head or upper spine near an electrified wire. Accidental head or neck contact can occur when pushing a voltage probe into the soil. Be careful when doing so to avoid head-to-wire contact!
- Never attempt to step over or climb through an energized fence of any kind.
- Never encourage anyone to touch an electric fence.
Start by measuring the voltage at the end of the fence line. If the voltage is below 3000V, follow these steps to determine if the problem is with the fence, or the energizer.
Test the energizer first!
- Turn off the energizer.
- Disconnect the wires going to the fence and ground stake/rod.
- Turn the energizer back on.
- Measure the voltage on the energizer between the two terminals (positive and negative) with a digital voltmeter or other high-voltage tester. Touch one end to “-“ (earth terminal) and the other end to “+” (fence terminal). The reading tells you how well the energizer is working without any other variables.
- If the tester reads below 5000V, then the energizer (or possibly the battery) is the problem. If the voltage is above 5000V, then the trouble lies with your fence.
If the fence is at fault:
- Conductors touching another wire, steel post or the soil
- Broken or damaged insulators

I was using a low impedance fencer on my electric fence for my horses. It worked fine this summer but once we got snow and a great deal of ice this winter , it was sending a very weak pulse that had no shock value. We have sandy soil also. In researching the problem, I came across information that convinced me I needed a wide impedance energizer. The only one I could find was the Kube 4000 Energizer online. It had good reviews so I decided to give it a try. I am now receiving a 5500 v plus pulse through my fence. I am well satisfied with this energizer.

An excellent product. We’ve used one for ten years without a single problem and bought another for a new pasture across the road. Wouldn’t hesitate to buy a 3rd.

A great little energizer. It does a much better job of generating a charge to the fence no matter the ground moisture conditions. We use this on portable fencing to rotationally graze a small herd of sheep and it works wonderfully.

Excellent energizer with no fancy bells and whistles but it will sure pop your tale. This energizer packs a punch and really works. We use it to keep our sheep and a ornery bull in their appropriate areas. We have had no issues at all, and we will probably be purchasing another in the near future.

The best fence charger in it's price range. This cherger outperforms chargers that cost twice as much. Just bought my second. The first lasted 12 years before it got fried by lightning.
