Key Terminology
AC | alternating current, AC (mains) power supply 110 – 120 V or 220 – 240 V. |
Amp | unit of current. Short for Ampere. |
Capacitors | used to store energy in the energizer (charger). |
Current | duration and magnitude of current causes the shock of 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 (charger). |
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 (charger) to the fence. |
Live | the current-carrying wire connected to the charger fence output terminal. |
Ohm | unit of resistance. |
Output Energy | effective energy delivered by the energizer (charger). |
Pulse | brief electrical current given by an energizer (charger), 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. |
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. |
