DDS833A Series DIN Rail Energy Meter

Application ：

Model DDS833A  three phase four wire electromechanical front board installed active energy meter is a kind of new style three phase four wire active energy meter, it is on the basis of original D86 three phase electromechanical meter, and fully absorb new technologies about electromechanical meter from domestic and abroad. The meter completely accord with relevant technical requirements of class 2 three phase active energy meter stipulated in international standard IEC 62053-11. It can accurate and directly measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net, it is use for setting indoor or out door meter box. The meter has novel design, rational structure, and it can display total energy consumption by drum wheel mechanical register. It has following features: high overload, power loss, long-life, specious appearance, etc. 

Standard configuration extended terminals cover, in order to protect to use electricity safely, may select short terminals cover.

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 and pulse machinery counter. May select 6+1 digits display .
Standard configuration one port of pulse output passive (polarity), May select increase a distant port of pulse output passive (no polarity), And contact with all kind of AMR system conveniently, complying with standard IEC 62053-31 and DIN 43864.
Bicolor LED instructions power state (green) and signal of power impulse (red).
Standard configuration don’t detect direction of the trend of load current. May select Automatic Detecting the direction of the trend of load current. And instructions (Only red power pulse signal when working, that is meaning the 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 and use, there are two types you may select. Standard configuration type S connection, may select type T connection.

Standard configuration extended terminals cover, in order to protect to use electricity safely, may select short terminals cover.
