▍He aha MCM?

● Tautoko ngawari mai i te tohu me te hangarau:I te mea ko te taiwhanga whakamatautau kaitaunaki o TUVRH me ITS i te Tiwhikete o Amerika ki te Raki, ka taea e MCM te mahi i nga momo whakamatautau katoa me te whakarato ratonga pai ake ma te whakawhiti hangarau kanohi ki te kanohi.

● Tautoko kaha mai i te hangarau:Kei a MCM nga taputapu whakamatautau katoa mo nga pākahiko o nga kaupapa nui-rahi, iti-rahi me te tino tika (arā, te motuka hiko hiko, te kaha rokiroki, me nga hua mamati hiko), ka taea te whakarato i te katoa.pūhikonga ratonga whakamatautau me te tiwhikete i Amerika Te Tai Tokerau, e hipoki ana i nga paerewa UL2580, UL1973, UL2271, UL1642, UL2054 me etahi atu.

Ko te Upoko 4 o te tono ka kaha te pa ki te hoahoa pākahiko: ina tangohia te whakaaro whakarereke mo te he o nga waahanga whakamarumaru me nga iahiko, ka mahia te whakamarumaru ma roto i nga iahiko e rua, nga waahanga ranei, me taapiri tetahi atu taputapu tiaki na te mea ko te ko nga mea taketake me he. Hei tauira, i roto i te whakamatautau utu nui, mena e rua nga MOSFET e whakamahia ana mo te whakamarumaru utu nui
me he ki te kore e mahi etahi atu hoahoa whakamarumaru utu nui, ka ngaro te pākahiko i te whakamarumaru utu nui ka kore e taea te whakamatautau.
