Диапазон частот и измеритель LoRaWAN
LoRaWAN определяет 10 региональных стандартов параметров (разработка узла LoRa — стандарты параметров LoRaWAN в разных регионах), но в некоторых
MID & Eichrecht - compliance of EV chargers
Note that so-called 'PTB compliant' chargers actually comply with the German calibration law (Eichrecht). Eichrecht = compliance with MID + “customer protection”: the customer must be able to check charge session data hours/days/months after the actual session...
What is DLMS meter? &What is DLMS compliant?
DLMS is short for DLMS: Device Language Message Specification. The DLMS / COSEM standard suite (IEC 62056 / EN 13757- 1) is the most widely accepted international standard for utility meter data exchange. This global acceptance is clearly demonstrated by the continued fast growth of the membership of the DLMS User Association...
What is the difference between M-Bus and MODBUS communication ?
M-Bus Communication: M-Bus is a communication protocol used between meters and the central data collection system or Pre-Payment unit. 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°...
