Dual Voltage Power Supply 12 Volt

This is the simple circuit diagram of Dual Voltage Power Supply. It is used for Misc… application. This circuit is called regulated power supply. For this reason the main component of this circuit is Regulator IC. It also needs few components to built. The regulator 7812 is the positive voltage regulator and  7912 is the negative voltage regulator. 

You can also use 7809 for 9 volt positive power supply and 7909 for negative voltage power supply. 

It regulates voltage from 24Volt to 12 Volt (DC). The transformer input is 110Volt to 220Volt (AC) and the output must be between 12Volt to 24Volt (AC) and current must be 500mA. In this circuit some capacitors are used as a filter for removing repole.

    The only reason for time is so that everything doesn't happen at once. See the link below for more info.

    This update is required for the controller to operate with the DC power supply. " explosion-proof power supply
