This single phase Din Rail Kwh meter is a new generation of single phase electronic watt hour meters, which uses microelectronic technologies, LSI circuits, and advanced digital and smt technologies. The meter is in compliance with the relevant technical requirements for Class 1, Class 2 and Iec62052-11, Iec62053-21. It accurately and directly measures 50/60 Hz active energy consumption from single-phase AC power grids. The current specification is an important parameter for energy meters because it indicates a meter's ability to accurately measure the power consumed by a user's electrical load. There are generally two parts to this specification: The Base Current (Ib) for Directly Connected Meters and the Maximum Current I Max. Of these current ratings, you will usually see the current specification defined in terms of Ib with the I Max value shown in parentheses. For example, some common values for the energy meter's current specification include 5 (40) A, 5 (80) A, or 10 (100) A.
