单词 | LV (Low Voltage) |
释义 | LV (Low Voltage) 1. A relatively low amount of electromotive force (emf).The LV grid runs at 110 volts at 50–60 Hz in North America, and 220 volts at 50 Hz in Europe and most of the rest of the world.Access broadband over power line (Access BPL) technology can make use of those LV lines as a portion of a local loop for broadband data communications. See also Access BPL, emf, HV, Hz, MV, volt, and voltage. 2. According to the International Electrotechnical Commission (IEC), alternating current (AC) voltage of 50–1,000V, or direct current (DC) voltage of 120–1,500V. Extra low voltage (ELV) is AC voltage less than 50V or DC voltage below 120V. Unlicensed personnel can safely install ELV wiring. See also AC, DC, and IEC. |
