1. Charaeristics and Range of application:
Model DTS791 three phase eleronic meter is a kind of new style three phase whole eleronic te meter, and adopt up to date micro-eleronics technique and imported special large scale integrate circuit, use advanced technique of dial sampling technique and T technics etc. The meter are completely conformed to the relative requirements of the National Standard GB/T17215.321-2008 and International Standard IEC1036 on the meter (Cl 1 or Cl 2).
The meter is used for measuring aive energy power consumption in a rated frequency of 50Hz or 60Hz three phase alternating current circuit. It can accurately and direly measure aive energy consumption from positive and reverse direions. It has following features: Good reliability, all volume, light weight, specious nice appearance, advanced technics. It can choose many kinds of installation ways such as 35mm DIN standard rail.
The meter is installed indoors. The site conditions shall be umed as follows: The ambient temperature is –25~55℃,relative humidity is not more than 95%. There isn’t heavy corrosive gas or any influence of dust, mold and inses etc.
