POWER	CIRCUIT OF USING

- ● Vcc(DC 5V)	POWER AROUND MICOM OR SENSOR SENSING PART

- ▶ V12(DC12V)	RELAY RUNNING PART

AC220V input power is decompressed through LVT(DC-TRANS), the power is changed DC vltg through DIODE rectification. It is an archery practive bow through 1000uF/35V CAPACITOR. And regular DC 12V is output through REGULATOR 7812, it is used to the RELAY runing power. The other of LVT(DC-TRANS) is an archery pratice bow through DIODE rectification or 1000Uf/35V CAPACITOR and it is output the regular DC5V through REGULATOR 7805.

And it is used sircumference circuit or various signal(Sensor,Switch) input power.
