 Meter - DDS623 series

Application
Model DDS623 single phase electronic front board installed active energy meter is 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 is use for setting indoor or out door, and this meter has seven digits LCD displays shows the active energy consumption. It has following features: good reliability, small volume, light weight, specious nice appearance, convenient installation, etc.

 

Functions and features
Front board three fixed installation, up and down mounting holes center distance is 130-147 mm, users can choose any one by themselves.
Seven digits display LCD, standard configuration 6+1 digits display (999999.1kWh). May select 5+2 digits display (Please specified when ordering).
Standard configuration one port of pulse output passive (polarity), May select increase a distant port of pulse output passive (nonpolarity). 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).
Automatic detection the direction of the flow of load current. And instructions by individual LED. (Only yellow energy impulse signal when working, that is meaning the direction of the flow of load current reverse).
Single direction single component measure single phase two wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21.
Direct connect operation, there are two types wiring you may select. Standard configuration type 1A wiring, may select type 1B wiring (Product Configuration code is JF).
Standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is CR).
