DEM011AH

SINGLE PHASE ELECTRONIC DIN-RAIL ACTIVE ENERGY METER

Application

Model DEM011AH single phase electronic DIN rail active energy meter is a kind of new style single phase two wire active energy meter, it adopt micro-electronics technique, and imported large scale integrate circuit, use advanced technique of digital and SMT techniques, etc. The meter completely accord with relevant technical requirements of class 1 single phase active energy meter stipulated in international standard IEC 62053-21. It can accurate and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net, it can display total energy consumption by step motor type impulse register. It has following features: good reliability, small volume, light weight, specious nice appearance, convenient installation, etc. This meter has already got the patent certificate from China State Intellectual Property Office at present. Patent certificate NO. ZL 2006 3 0106828.1, any other country patent certificate are in assessing.

Functions and features

● 35mm standard DIN rail installation, complying with standard DIN EN50022. Or front board setting (mounting holes center distance 63 mm), users can choose any one by themselves.
● Six pole width (Modulus 12.5mm), complying with standard JB/T7121-1993.
● Standard configuration 5+1 digits display (99999.1kWh) by step motor type impulse register. May select 6+1 digits display (Product Configuration code is SC).
● Standard configuration one port of pulse output passive (polarity), May select increase a distant port of pulse output passive (nonpolarity), (Product Configuration code is AJ). And contact with all kind of AMR system conveniently, complying with standard IEC 62053-31 and DIN 43864.
● Two LED instructions power supply state (green) and signal of energy impulse (red).
● Standard configuration don’t detection direction of the flow of load current. May select automatic detection the direction of the flow of load current. And instructions (Only red energy impulse signal when working, that is meaning the direction of the flow of load current reverse).
● Single direction measure single phase two wire active Power consumption. It is nothing with direction of the trend of load current. Complying with standard IEC 62053-21.
● Directly connect operation, there is two types wiring you may select. Standard configuration type S wiring, may select type Twiring (Product Configuration code is TH).
● Standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is AG).
