APPLICATION

EM341CM THREE PHASE FOUR WIRE ELECTRONIC MULTI-RATE FRONT BOARD INSTALLED ACTIVE ENERGY METER

Application
Model EM341CM three phase four wire electronic multi-rate front board installed active energy meter is a kind of three phase four wire two tariffs (tariff conversion is controlled by timer outside or similar equipment) 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 four wire AC electricity net, it is use for setting indoor or out door meter box. This meter has seven digits LCD displays shows various consumption data and information. It has following features: good reliability, light weight, specious nice appearance, convenient installation, etc.

Functions and features
● Front board three fixed installation, up and down mounting holes center distance is 198-212 mm, users can choose any one by themselves.
● Have two tariffs, and port of set the tariff, input control voltage 0-90 Vac, set up tariff F1, input control voltage 150-400 Vac, set up tariff F2, the tariff conversion is controlled by timer outside or similar equipment.
● Standard configuration cycle display every 5 second, it can display 6 data at most. Can select the data which displayed. The decimal median which displayed can choose set one or two. (Default two decimal, please specified when ordering)
● Use memory that is not loss easy, the data can be kept forever after power cut off.
● There are a polarity port of pulse output passive closed and a nonpolarity port of pulse output passive distant, the output rate is 10 or 100 imp/kWh (can select), Complying with standard IEC 62053-31 and DIN 43864.
● Eight LED instructions respectively power supply state, signal of energy impulse, the direction of the flow of load current, and the state rates just now
● Single direction three components measure three phase four wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21.
● Standard configuration for direct connect operation, type 16B wiring, we can also choose another type of wiring, and use CT (Product Configuration code is CO) and PT & CT (Product Configuration code is CQ ), type 48B wiring for operation.
● Standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is CL).
