Key Terminology
AC | Alternating current, AC power supply 110 - 120 V or 220 - 240 V. |
Amp | Unit of current. Short for Ampere. |
Capacitors | Used to store energy in the energizer. |
Current | Duration and magnitude of current causes the shock given by the electric fence. Increasing the voltage increases current, while increasing resistance decreases current. |
DC | Direct current, battery power supply (e.g. 12 V battery input). |
Fault / Short | Energy loss from the fence (i.e. live wire lying on the ground, vegetation growing over the fence, etc.). |
Ground System | The rod(s) in the ground connected to the ground terminal on the energizer. |
Joule | Unit of energy. One joule is one watt of power for one second. |
Lead Out Wire | Section of underground cable or wire that carries the electrical current from the energizer to the fence. |
Live | The current-carrying wire connected to the energizer fence output terminal. |
Ohm | Unit of resistance. |
Output Energy | Effective energy delivered by the energizer. Also known as output joules. |
Pulse | Brief electrical current given by an energizer, approximately 0.0003 seconds per pulse. |
Resistance | What causes loss of power and voltage on the fence. |
Stored Energy | Energy accumulated in the storage capacitor(s) in between output pulses. Also known as stored joules. |
Watt | Unit of power. One watt is one joule per second. |
Volt | Unit of electrical pressure. Sometimes it is stated as “kV” or kilovolts which is equal to 1,000 volts. |
Voltage | Electrical pressure causing current to flow. |
