APPLICATION

EM024DB THREE PHASE THREE WIRE ELECTRONIC DIN-RAIL ACTIVE ENERGY METER

Application
Model EM024DB three phase three wire electronic DIN rail active energy meter is a kind of new style three phase three wire electronic 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, and also a new three phase three wire active energy meter. The meter completely accord with relevant technical requirements of class 1 three phase active energy meter stipulated in international standard IEC 62053-21. It can accurate and directly measure 50Hz or 60Hz active energy consumption from three phase three wire 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. The patent certificate of this meter is in assessing in the China State Intellectual Property Office at present.

Functions and features
● 35mm standard DIN- rail installation, complying with standard DIN EN50022.
● Four pole width (Modulus 17.5mm), complying with standard DIN43880.
● Standard configuration 6+1 digits display (999999.1kWh) by step motor type impulse register. May select 5+1 digits display (99999.1kWh).
● Standard configuration pulse output passive (polarity), May select distant impulse output passive (nonpolarity). And contact with all kind of AMR system conveniently, Complying with standard IEC 62053-31 and DIN 43864.
● Three LED respectively instructions power supply state (line voltage L12 & L32) and signal of energy impulse.
● Automatic detection the direction of the flow of load current. And Instructions on individual LED
● Single direction two components measure three phase three wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21.
● Standard configuration type S wiring (Inlet from bottom, outlet from top) for direct connect operation, we can also choose another type of wiring, and use CT (Product Configuration code is CB) and PT & CT (Product Configuration code is BB) for operation.
● Extension terminals cover, in order to protect to use safety.
