English to Portuguese Tech/Engineering Electronics / Elect Eng carrier voltage

O Eurodic dá Tensão da Portadora, mas como é português de Portugal, me pergunto se haverá tradução mais brasileira.

Even though the active terminating resistor supplies a 2.5 volt carrier voltage for the CAN Hi and CAN Lo lines, each control unit also transmits a small voltage on the CAN-BUS. In general, as control units are added to the CAN-BUS, the 2.5 volt ***carrier voltage*** will change slightly, CAN Hi should always remain between 2.5 – 3.5 V and CAN Lo should always remain between 1.5 – 2.5 V.
