|
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. |
