automatic turn ON and turn OFF circuit

[j.v.s.swathi]

i want a circuit such that you are able to periodically
switch ON and OFF AC power supply to the electric shock machine.
Time period should be observable and less than 10 sec

Hi j.v.s.swathi
One of the simplest ways is using a triac and a trigger circuit . but there are several options available too . but it depends on you and your required current and type of your load .

...electric shock machine...

8-O Can you describe device with more details.


You can try this repeating timer, circuit and PCB working 100% :



Pins 5 and 6 should be linked with 9 and 11 pins.

Power consuption:
Off state 11uA
On state 30mA (depends from relay coil current)

Output first state after power on is OFF.

your circuit is good.but if there is a reset button then i think it should be perfect.

For the switching device you have some choices. You can use:

• Triac
• SCRs
• Relay
• Solid State Relay
• MOSFET (with some supporting circuitry to allow switching of AC)
• IGBT (with some supporting circuitry to allow switching of AC)

Your method of drive will depend on the selected device.

For the controlling you will need a device that keeps track of the time and sends output drive signals as necessary. This will depend on your desired method of control. If you just require a repeating timer circuit, you can use the one shown by tpetar.

Hope this helps.
Tahmid.

What reset should do?

You can use TRIAC as a switch by using opto-triac(MOC3041) it has a zero-crossing activation facility and for generate time delay you can use 555 Timer IC.
