2、Rail energy meter

2.1 Overview

The meter uses DIN35mm rail mounting structure, LCD display, measurement of electrical energy and other electrical parameters, can be clock, rate of time parameters such as measurement, and with electrical energy pulse output; available RS485 communication interface and the host computer to achieve data exchange.

The watt-hour meter has the advantages of compact size, high precision, good reliability and convenient installation, and the performance indexes conform to the technical requirements of the national standard GB / T17215-2002, GB / T17883-1999 and the power industry standard DL / T614-2007 Requirements, applicable to government agencies and large public buildings in the measurement of electrical energy can also be used for enterprises and institutions for energy management assessment.
