PrimaShock™ 8 Fence Energizers & Kits
New! 8 joule output dual-power (AC/DC) fence energizer. Provides ample power for your ranch or large grazing operation. Low-impedance circuitry generates a short, strong pulse to cope with weeds and other green vegetation.
- Low cost per joule: 8J output
- Adaptable for plug-in (AC), or battery (DC) operation
- 5 operating modes to suit your situation
- Digital LCD shows energizer output voltage, pulses per second and battery voltage (when used as a DC unit.)
- Day/night and battery saving modes

- 8 released joules
- 12 stored joules
- 8 joules in moist soils
- 0.76 joules in dry soils
- 6-8 miles of 3 strand cattle fence
- 4 miles of a 5-7 strand sheep fence
- 30-34 rolls of 164' sheep/goat nets
- 15-17 rolls of 164' poultry nets
- Requires a grounding system. Inadequate grounding is the most common failure in an electric fence system. We recommend 24 ft. of grounding for this energizer.
- 110V draw is 4 watts per hour
- 12V battery draw is 150-330 milliampere (mA) per hour. With this energizer, a 12V, 100 ampere hour deep-cycle battery will last 4 days. (Assumes 60% drawn down between charges.)
- To operate as a solar energizer, run the unit as a battery unit (DC) and attach a solar panel to charge the battery. (50-70 watt panel recommended.)
- Dimensions: 10"W x 8"H x 4"D
- Integrated on/off switch
- LCD display for output voltage and battery condition. (Replace or charge battery when battery voltage drops below 12.2V)
- 110V plug-in adapter (6' cord)
- 12V battery adapter. (Batteries sold separately.)
- A wiring harness is included to connect energizer to fence and energizer to ground rod. (A battery harness is not included and must be purchased separately unless purchasing the Battery Kit.)
- 5 operating modes:
- Full Energy—pulses every 1.2 seconds
- Reduced Energy—output power is reduced 25%, energizer pulses every 1.2 seconds
- Short-day/Long-night—daytime pulse every 1.2 seconds, 2 seconds at night. Best used for day grazing with low predator pressure.
- Long-day/Short-night—daytime pulse every 2 seconds, night pulse every 1.2 seconds. Use with well-trained livestock exposed to heavy predator pressure at night.
- Battery Saving—output power reduced 25% and pulses occur every 2 seconds. Best for well-trained livestock and low predator pressure.
To use the energizer as a plug-in unit:The energizer can be mounted either inside or outside of a building. The energizer must be mounted vertically. If placing outside, 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. (Batteries sold separately.)
- 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-tic sound will be heard. If the indicator light doesn't flash, then the unit/battery should be checked.
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.
- If using the energizer as a battery unit, do not charge the battery while the energizer is connected to the battery.
- Test the energizer first.
- Turn off energizer.
- Disconnect ground wire and the fence wire.
- Turn energizer back on.
- With fence tester, put the ground probe (or clamp) to the ground terminal on the energizer and the metal loop (or positive clamp) at the top of the tester to the fence/positive terminal. The reading you get tells you how well the energizer is working without any other variables. If there is a very low voltage (under 4000V) or no voltage, then the energizer may have a problem. If the voltage is high (greater than 4000V) then the trouble lies with your fence. Most energizers put out between 5000V and 8000V when there is no load (i.e. no fence hooked up).
- Check that the 110V outlet is "live" by using a plug-in drill or test light.
- If the test light works and the energizer does not, call Premier.
- 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.
If you lack a Fault Finder…
- 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.
Listed below are recommended optional components or related items. Your particular situation may require alternative recommendations. Please call and talk to our consultants if there are any questions at 800-282-6631.
