Single-phase DIN rail mounted kWh meter

by Velleman

This single-phase DIN rail kWh meter is a new generation of single-phase electronic watt-hour meters, adopting micro-electronic techniques, LSI circuits and advanced digital and SMT techniques.

The meter is in conformity with the relevant technical requirements of Class 1, Class 2 and IEC62052-11, IEC62053-21.

It accurately and directly measures 50/60 Hz active energy consumption from single-phase AC electricity grids.

The current specification is an important parameter for energy meters as it signifies 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 basic current (Ib) for direct-connected meters and the maximum current I max. Of these current ratings, you will typically 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 current specification include 5 (40) A, 5 (80) A or 10 (100) A.
