Pengujian Alat Catu daya
AN 7805 220V
3A
12V
220uF/25V 10uF/25V
5V 100uF/50V
Di beri masukan dari PLN sebesar 200 V ke Trafo 3A kemudian di turunkan menjadi
11.43 V. Tegangan 11.43 V dari trafo di searahkan dengan menggunakan dioda 3A
sehingga di peroleh 11.43 V, untuk menjaga kesetabilan tegangan maka tegangan akan
di filter menggunakan capasitor. Ic regulator AN 7805 di gunakan untuk out put
tegangan 5 V.
Dari rancangan di atas output nya adalah 5 V, dari hasil pengujian peroleh Outputnya
adalah 5,03 V.
