Transformerless Power Supply (CB516E)

The output voltage depends on the zener diode. Zener in the range between 1.2 to 12 V rated to 1 W can be used. The current sourced to the load is up to 30 A. C1 is a polyester capacitor with a working voltage of 600 V at least. The circuit can operate in the 110 V AC line or 220 VAC line.
