 Meter -DEM623SS series

Model DEM623SS 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. It has its completely independent intellectual property rights and minimum size. It has already passed the test of the international authority KEMA. 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 0119356.3, any other country patent certificate are in assessing.


Functions and features
°Ů35mm standard DIN rail installation, complying with standard DIN EN50022.
°ŮSingle pole width (Modulus 17.5mm), complying with standard DIN43880.
°ŮStandard configuration 6+1 digits display (999999.1kWh) by step motor type impulse register. May select 5+1 digits display
°ŮStandard 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.
°ŮBicolor LED instructions power supply state (green) and signal of energy impulse (red).
°ŮAutomatic 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).
°ŮSingle 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.
°ŮDirectly 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).
°ŮExtension terminals cover, in order to protect to use safety.
