Tus nqi ntawm tus tawg-pov thawj tswj lub thawv varies raws li nws cov configuration. Txij thaum cov thawv no ua raws li circuit diagrams, Yog tsis muaj nqi tas. Txawv configurations ua rau txawv pricing.
Tus kwv yees li ntawm tus nqi yog raws li qhov ntau lawm drawings. Ntau yam cawv tus nqi, xws li thawv, hom internal components, Qhov muaj nuj nqis ntawm cov components, Cov vaj huam sib luag cutouts, Qhov zoo tshaj ntawm xaiv vaj huam sib luag components, thiab muaj nuj nqis ntawm indicator teeb, khawm, thiab xaiv switches.
Lwm qhov tseem ceeb heev yog tus tawg-pov thawj qib uas tswj lub thawv. IIB thiab IIC muaj ntau txoj kev manufacturing txheej txheem, Nrog IIC tau ntau txoj thiab, tshwj xeeb tshaj yog, kim kim tshaj plaws.
