Speedrite 12000i Energizer
Advanced low impedance electric fence energizer offers uncompromising performance and a no-nonsense approach to livestock control.
Dual purpose: can be plugged in or used with a 12V battery. This unit is ideal for large and medium sized farms away from the public. Can be used with a remote/fault finder to make working on fences more efficient, but remote is not included.
Batteries sold separately.
Can be controlled with a remote control sold separately (see under accessories tab).
- 16 stored joules
- 12 released joules
- 6.89 joules in moist soils
- .60 joules in dry soils
- Includes a battery lead set.
- Has a 110V plug on a 5' cord.
- 2 prong plug.
- Includes an on/off switch.
- 12V DC draw: 1100 mA/hr
- 110V draw is 11 watts per hour
- Draws 1100 mA per hour on the fast setting and 600 mA per hour on the slow setting.
- Will last 2.5* days when set to the fast pulse and 4* days when set to the slow pulse. *Assumes being drawn down to 40% between recharges.
- Indicator lights show output voltage and battery condition.
- Backlit LCD screen displays output voltage, battery voltage and earth voltage.
- Has multiple pulse settings.
- Slow setting- approximately 2.5 seconds between pulses. Use where unknowing visitors may accidentally touch the fence or where livestock/predator pressure is low. 25 pulses per minute.
- Fast pulse at night and slow during the day. Use for nocturnal livestock and predators or when visitors are more likely to be around.
- Slow at night and fast during the day. Use when pressure is higher during the day than at night (diurnal livestock).
- Fast setting- Pulse rate is approximately 1.5 seconds. Use when animal pressure is great and where no visitors may contact the fence. 40 pulses per minute.
- Manufactured by Tru Test.
Miscellaneous—see under Accessories tab
- Requires 36 ft of ground rod
- Can be used as a solar energizer by using a 90-120 watt solar panel
- Can be controlled with a remote control, but sold separately.
- 5 miles of a 5-7 strand fence
- 40 of the 164' sheep/goat nets
- 20 of the 164' poultry nets
- Low-impedance units work effectively with high weed/grass loads, but not as well with dry soils or poor conductors.
- Safe to use with all polywires, polyropes, tapes and electrified nets.
- Modular so it can be easily repaired.
To use the energizer as a plug-in unit:The energizer can be mounted either inside or outside of a building, but not where there is risk of fire. The energizer must be mounted vertically. Protect the energizer from direct rainfall.
- Connect an insulated cable (stripped back 1 - 2" on ends) to the fence terminal on energizer, run the cable to the fence line and connect, or use the positive part of the wiring harness.
- Then run a second length of cable from the ground terminal (with ends stripped again) on the energizer to the ground rod(s), or use the negative part of the wiring harness.
- Secure to ground rod(s) 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.
To use the energizer as a battery unit:
- Attach wiring harness to energizer.
- Attach the bare end of the wire with the red clip to the fence terminal of the energizer. Attach the red alligator clip to the fence.
- Attach the bare end of the wire with the green clip to the ground terminal of the energizer. Attach green alligator clip to the ground rod(s).
- Connect the energizer to the battery.
- Insert battery adapter into the energizer. Attach red alligator clip from the adapter to the red “+” terminal of the battery.
- Attach black alligator clip from the adapter to the black “–” terminal of the battery.
Unit indicator light should flash and a tic-tac sound will be heard. If the indicator light doesn't flash, then the unit/battery should be checked.
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
- Warning: Powerful high joule unit. Use with caution. Do not use with fences near children, visitors or the public.
- Make sure the energizer is turned off before working on the fence or the energizer.
- Use on size appropriate fences
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.

Very wet spring in Missouri, having problems keeping miles of sheep fence hot. Replaced a 10j unit with this 12j and immediately had an increase in voltage BUT far more important to me, this charged was able to 'brown off' leaves FAR better.
