Automatic Power Off Circuit Diagram

It is an automatic power off circuit diagram.  If you need to shut-off any electronic device after a set amount of time then this circuit can do that automatically; when you are even sleeping!  For example this auto power off circuit can be used with garden/porch light, soldering iron/ glue gun or similar other devices to auto shut it off for saving electricity or save the device, or you can use it to suit your own needs.

Ceiling fan wiring diagram - with capacitor connection

Simple Wiring diagram of ceiling fan


Fig-1:  Ceiling fan wiring diagram

This is a simple illustrated circuit diagram of ceiling fan. To be noted that the wiring diagram is for AC 220V single phase line with single phase ceiling fan motor. Here a simple SPST switch is used to supply power or not to the fan motor and a Regulator is used to controlling the fan speed. Though it is very simple, but one thing to be noted that Switch and Regulator should be connected with the phase line of main power, not neutral.

Ceiling Fan Regulator Circuit - Motor Speed Controller

This is a simple ceiling fan regulator circuit diagram tutorial. It is used to control the speed of a ceiling fan. In the other words it is an AC motor speed controller circuit, as because it's control the speed of a AC motor(Ceiling Fan).  This ceiling fan regulator circuit built with few numbers of parts. The circuit mainly  based on Z0607 TRIAC. This is a low power AC semiconductor device. Generally which is used to controlling speed of low power ac motor speed.
