  1 Overview

  The rail type multi-function meter adopts DIN35mm rail-mounted structure and LCD display to measure electric energy and other electrical parameters. It can set parameters such as clock and rate period, and has power pulse output function. It can exchange data with the host computer through RS485 communication interface. .

  The electric energy meter has the advantages of small size, high precision, good reliability, convenient installation, etc. The performance indicators conform to the national standard GB/T 17215-2002, GB/T 17883-1999 and the power industry standard DL/T614-2007 for the electric energy meter. The technical requirements apply to the sub-item measurement of electric energy in government agencies and large-scale public construction, and can also be used for energy management assessment in enterprises and institutions.
