REGULATORS BASED DUAL VOLTAGE POWER SUPPLY

The following circuit Diagram of (DUAL VOLTAGE POWER SUPPLY ) can be used for Miscellaneous application.
It requires a few components to built. The most important components of this circuit are REGULATORS.

  • (AN) 7812 : is the Positive Voltage Regulator, it regulates the voltage from (almost) 24vDC to 12vDC (accurate).
  • (AN) 7912 AN7912 is the Negative Voltage Regulator. It regulates the voltage from (almost) -24vDC to -12vDC.

A transformer output must be between 12vAC to 24vAC @ 500mA. Input of transformer (Primary) should be about 110vAc-220vAC. It also include some capacitors to filter the current.
