The Power Supply  Unit.

This is used normal step down transformer (400ma) for generating three type of deference voltages & 100 AC volt for rigging.

It doesn’t provided a PCB pattern for the power supply unit. So a Vero board can be used to build the unit.

Parts List :

1.Step down transformer ( 230 V to 30 V , 15 V  & 100 V )
2.Two bridged 1 A rectifiers
3.7805 – 5V regulator
4.7812 – 12V regulator
5.1000 uf – 35 V
6.1000 uf – 16 v
7.150 ma fuse & it’s holders.
8.Necessary Wires & a wire code for AC supply.
