Electric Fence Circuit Diagram 555 - 21 Images

The first timer u1 is operated astable as an oscillator.

Electric fence circuit diagram 555. It uses 2x 555 timers one runs in astable mode and is used to generate the frequency interval while the second one controls the pulse length and so the output voltage. How an electric fence works an electric fence energizer converts mains or battery power into a high voltage pulse. The circuit runs on 12v batteries making this a very portable fence energizer solution. The pulse emitted by the electric fence is high in voltage but limited in power because the pulses duration is very short.

The fence charger circuit is able to produce voltage pulses up to 20 000 volts needless to say about the fatality rate involved with it. According to the circuit diagram when ldr detects any activity the output of the op amp ic goes low and pnp transistor t1 start conducting. The energizer fence terminal positive is connected to the insulated fence wires and the energizer ground terminal negative is connected to galvanized metal rods driven into the ground. An electric fence circuit is made on a larger scale.

The same circuit completion second diagram above is necessary before the animal gets a shock. The pulse itself is only around 150 microseconds long. You need the. An electric circuit prototype of electric fence energizer equipment for livestock use was implemented and the results are showed.

It doesn t kill as the output current is limited but it is definitely not for those with medical heart problems. 20 kv from the sparks. This work is based on a study developed in a master thesis. Hence the led starts glowing and the 555 timer ic get triggered.

Electric fence charger circuit by using ic ne555 x1 is a small iron core step down transformer 230v ac primary to 12v 1a secondary that must be reverse connected i e the secondary winding terminals of the transformer should be connected between the emitter and ground and the output is taken across the primary winding. The energizer releases this pulse on to an insulated fence line about once every second. This circuit uses two 555 timer ic s to create pulses. U1 determines how often the pulses will be generated.

The present circuit of an electric fence charger is designed and tested by me and has proved sufficiently powerful for the application. Schematic and pcb design. An astable 555 oscillator circuit for a more detailed description see the notes section of the 3 6v strobe light drives the base of a high voltage high current transistor through a 100r resistor.
