Speedrite AN90 Energizer
Advanced low impedance electric fence energizer offers uncompromising performance and a no-nonsense approach to livestock control.
This unit offers unique power settings with different pulse rates to help conserve battery power.
This is a portable, simple battery energizer that is used for temporary or short lengths of fence to keep in horses or cattle. Ideal for strip grazing
Will draw from 4 D cell batteries or an external 6V or 12V lead-acid battery (not included).

Common Uses
Specs
Should power…**
- 1320' of multi-strand fence that has minimal grass load
Miscellaneous
- Will draw from a 12V deep cycle battery or 4 D cell batteries (not included)
- 12V DC draw: 31 mA/hr. when set on the 'fast pulse' setting and 19 when set to the 'slow pulse' setting. With this energizer a 12V 100 ampere hour, deep cycle battery will last 80* days when set on the fast setting and 131* days when set on the slow setting. *Assumes being drawn down to 40% between recharges.
Energizer Specifications

- 0.12 joules in moist soils
- 0.09 joules in dry soils
- Pulses per minute: 38
- Ground rod, built-in
- Impedance type: Low
- Input: (DC) 6V/12V battery
- 6V/12V DC draw: 31 mA/hr
- Wiring harness to connect energizer to fence and energizer to ground rod

- Stand with convenient carry handle and step in plate
- Includes an on/off switch
- Has 2 pulse settings to adapt to various situations:
- 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 setting—Pulse rate is approximately 1.5 seconds. Use when animal pressure is higher and where no visitors may contact the fence. 40 pulses per minute.
Benefits
Installation
- Connect red lead's spade connector to fence terminal on top of energizer and clip other end of lead to fence
- Connect green clip to the ground rod/stake.
- Push black on/off button to desired setting (fast pulse or slow pulse) to turn on.
- Test fence.
Troubleshooting
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 energizer is at fault:
- Test the battery with a low-voltage tester; recharge if lower than 12.2 volts
- Check the grounding system
If the fence is at fault:
- Conductors touching another wire, steel post or the soil
- Broken or damaged insulators
Precautions
- Make sure the power is turned off before working on the fence or the energizer.
- Make sure the fence line is clear of grass and debris that may lower the fence’s voltage.
- Nickel Cadmium batteries are not recommended. The energizer's pulse speed will become slower and operation between recharges may be as short as 1 week with Nickel Cadmium batteries.
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.

Easy to set up. Not for use as a permanent fence unless you have rechargeable batteries.
Lynn R from Missouri
I watched a video on YouTube on how to put this together and how to use it. It’s user friendly, but I don’t think I would have purchased it without watching the video first. I will be using it for a camping trip that doesn’t have stall. Right now I have it on a small electric fence for horses.
Joseph S from Pennsylvania
Works like a charm. Using it on about 200' of fence. So easy to locate and use. I test regularly and am reading 5800 volts. Four D cells makes this a great choice for a seasonal garden. Security cameras haven’t picked up any tests yet but with tons of squirrels and raccoons, I’m sure to get a good shot.

This is my 4th time to purchase this fence energizer. They are that good. I use them on my pastured hens and on my sheep. With rechargeable D cells they are very cost efficient to run and last nearly a month between battery changes. Since using them I have stopped predation on my poultry. They would also work great for gardens.

This energizer is excellent, I like the portability.
