New kilowatt hour meters single phase

The rising energy cost requires users, especially of commercial, institutional and industrial installation, to measure the energy used by individual electrical loads. These energy measurement inputs allow users to analyse and define ways to optimise their electrical equipment and reduce energy consumption.
The new range of KWH meter, EC050 and EC051, provides a simple direct reading of energy consumption in the measured single-phase circuit, from 20mA up to 32A, without the use of current transformer. EC051 is integrated with a pulsed output for remote indication or linkage to an energy management system. The compact size of only 1 module width, ie 17.5mm, and modular din-rail design allows easy mounting into new or existing installation.

EC050

Single phase kwhmeter direct connection up to 32A

EC051

Single phase kwhmeter direct connection up to 32A with pulsed output
