In this video I made transformerless 220vac to 12vdc converter circuit. I add 10D 471k mov for surge protection. Some time government electricity come over 265vac in this case move will demage and safe rest of the components.
Components.
-Piece of zero pcb
-450v 155j polyester myler film capacitor.
-10A bridge rectifier kpb1010
-330 ohm 2 watt resistor
-MOV 10D 471k
-400v 4.7uf electrolytic capacitor
-12v 1 watt zener diode X 2
-2 point connector X 2
-2 wires and AC 2 pin plug
-some wires to connect components
