Widely used on new projects where the building infrastructure can be designed accordingly.M-Bus is available on a wide variety of gas, heat, electricity, and cold/hot water meters.
What is Four Quadrant Metrology?
P—active energy; Q—reactive energy; QL—inductive reactive energy; QC—capacitive reactive energy; S—apparent power Forward active power: P=UICOSΦ, where the range of Φ is within ±90°. Reverse active power: P=UICOSΦ, where Φ ranges from 90° to 270° Forward reactive power: P= UISINΦ, where the range of Φ is within 0~180°...
What are the differences between RS232, RS485, RS422 and RJ45 interfaces
RS-232, RS-422 and RS-485 are serial data interface standards.
