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 a 12v deep cycle battery or 4 D cell batteries (not included).
- Stored joules .16
- Released joules .12
- .08 joules in moist soils
- .09 joules in dry soils
- Comes with wiring harness to connect energizer to fence and energizer to ground rod.
- Comes with 12v leads to connect to an external 12v battery.
- 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.
- Will draw from a 12v deep cycle battery or 4 D cell batteries (not included).
- Draw from a 12v battery is 31 milliampere(mA) per hour 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 charges.
- The ground rod is built in.
- Manufactured by Tru Test.
- 1320' of multi-strand fence that has minimal grass load. Distance is dependent on amount of grass/weed load on the fence.
- 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.
- 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.
- To check—first turn off the energizer.
- Then disconnect the wires going to the fence and ground rod system.
- Turn the energizer back on.
- Then measure the voltage on the energizer between the 2 terminals (fence and earth) with a Digital Fence Voltmeter or other fence testing device. Touch one end to “–” earth terminal and the other end to “+” fence terminal.
- If the tester reads under 4000v, the energizer (or possibly the battery if it’s a battery/solar energizer) is the problem.
- If the tester reads more than 4000 volts, the energizer is working properly and the fence is the problem.
- If it's a 12 volt energizer carry the unit to a nearby vehicle and attach the input cords carefully to the vehicle's battery.
- If the energizer now works, then your fencer's battery needs to be recharged or replaced.
- If the energizer does not work, then you should call Premier re. repairs.
- Walk or drive along the fence looking for any point in which the energized wires touch the soil, a steel post or a steel wire. On HT wire fences, check the wires at braces to see if they are touching a hot wire. On netting, look for a hot wire touching the metal stake at the bottom of the plastic posts. Also look for damaged insulators.
- If the fence can be separated into several parts (by switches or by disconnecting parts of it), you can locate the problem by beginning at the far end and then progressively turn off or disconnect the sections of fence. When the voltage on the remaining fence rises sharply, you've located the section(s) that's causing the problems.
- The alternative to (2.) is to begin at the fencer and progressively turn on sections of the fence. When the voltage suddenly drops you can assume that the problem is in the section most recently connected.
Most energizers put out between 5000v and 8000v when there is no load (i.e. no fence hooked up).
If the energizer is faulty and you are using a battery unit you need to learn if the battery or the energizer is the problem…

Just set this up to keep our horses and mini horses out of the orchard when the apples are ripening. So easy and works great. I'm going to use the same set up for camping -- best I've seen. The built in grounding rod isn't long but I poured a bucket of water on the soil and it's working fine.

We use the fence for sheep in our back yard. It works great! I can't imagine how well 2-"D" cell batteries can do such a good job! It didn't take the sheep and our dog long to find out what it was! Be sure to buy the drive-able posts! I use a rubber mallet for easy installation.

Used to keep deer, chickens, woodchucks and whatever else wanders by out of a small 30x30 garden. Seems to be doing the job. The unit is easy to set up and move with the fence.

First used the 1980's version of this charger for rotational grazing with my sheep and loved it. Chose the current (pardon the pun) version to use on my permanet garden fence and it works like a charm, keeping dogs, bunnies and groundhogs at bay so far. Love your products!
