● I-DSYB, ngokwesiseko se-DST / DSY ebukhali, i-resistors inokuxhotyiswa ngesixhobo sokulawula ubushushu, ukwenzela ukhuseleko, ubuhle kunye nokulula, sincoma ukuba kufuneka yenziwe ibe yibhanki yomthwalo, enokuqonda ukufakwa kobushushu. i-fan yokulahla, ukhuseleko lokulawula ubushushu, ukhuseleko olugqithisiweyo kunye nokugqithisa, isixhobo se-alamu, umboniso wedijithali osebenzayo (umboniso wedijithali wamandla, ukuxhathisa, okwangoku, i-voltage, i-frequency, njl.) kunye neyunithi enye ene-AC kunye ne-DC yeenjongo ezimbini.
● Iifeni, izixhobo, izixhobo zokukhusela, izixhobo ze-alam, njl.njl zinokufumaneka, iifeni zifakwa ngokubanzi ezantsi okanye zinokufakelwa emacaleni;
● Inqanaba ezibini okanye ezithathu zingalungelelaniswa, iyunithi enye AC / DC njongo-mbini, inokubonisa amandla, ukumelana, okwangoku, umbane, ukuphindaphinda, njl.
