Specifications DDS6789 single phase acive electronic energy meter meet IEC61036:2000 standard, DIN-RAIL installation. Specifications  single phase electronic Din-rail Meter 
standard IEC 62053-21 Name: single phase electronic DIN-Rail Meter   Application   DDS1977 single phase electronic din-rail meter is a kind of new style single phase two wire active energy meter, single phase electronic din-rail meter adopt micro-electronics technique, and imported large scale integrate circuit, use advanced technique of digital and SMT techniques, etc. It has its completely independent intellectual property rights and minimum size.  The meter completely accord with relevant technical requirements of class 1 single phase active energy meter stipulated in international standard IEC 62053-21. single phase electronic din-rail meter 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.    Functions and features 1. 35mm standard DIN rail installation, complying with standard DIN EN50022.
2. Single pole width (Modulus 17.5mm), complying with standard DIN43880.
3. Standard configuration 6+1 digits display (999999.1kWh) by step motor type impulse register. May select 5+1 digits display
4. Standard configuration pulse output passive (polarity), May select distant pulse output passive (nonpolarity). And contact with
all kind of AMR system conveniently, Complying with standard IEC 62053-31 and DIN 43864.
5. Bicolor LED instructions power supply state (green) and signal of energy impulse (red).            
6. Automatic detection the direction of the flow of load current. And instructions (Only red energy impulse signal when working ,If no green instructions power supply, that is meaning the direction of the flow of load current reverse).
7. Single direction measurement single phase two wire active power consumption. It is nothing with direction of the trend of load current. Complying with standard IEC 62053-21.
8. Directly connect and use, there are two types wiring you may select. Standard configuration type S connection, may select type U connection (Product Configuration code is US).
9. Extension terminals cover, in order to protect to use safety.   Technical parameters
