Transformerless Power Supply 12v 500ma Circuit Diagram

To power low current demanding logic circuits and microprocessor circuits transformerless power supply is an ideal solution.

Transformerless power supply 12v 500ma circuit diagram.

Trophy points 18 activity points. And a whole lot more. The above diagram represents the transformerless power supply 12v. These power supplies have distinct advantages and disadvantages.

These are cost effective and consume less space so the gadget becomes handy. Lab power supply using lm7805 lm7806 lm7809 lm7812 ics. A circuit of transformerless power supply which is capable of providing 3 to 12 volt dc output. It is nothing but converting 220v main ac voltage to 12v dc voltage with the use of the capacitor resistor bridge rectifier and zener diode.

We can convert the high voltage ac into low voltage such as 5v 6v 9v 12v dc without using the transformer which is called transformerless power supply. But the low current efficiency makes them non ideal to satisfy high current. 12v 5v power supply. These type of transformerless power supplies are very handy to build contain very few parts.

Transformerless power supply 230 volt to 12v 500ma thread starter bjtpower. Here is the circuit diagram and explanation for transformerless power supply.
