APPLICATION

EM315GF SINGLE PHASE ELECTRONIC FRONT BOARD INSTALLED ACTIVE ENERGY METER

Application
Model EM315GF single phase electronic front board installed 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. 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 is use for setting indoor or out door, and this meter has seven digits LCD displays shows the active energy consumption. And there are far infrared and RS485 communication module in it. Contact with all kind of AMR system conveniently. It has following features: good reliability, small volume, light weight, specious nice appearance, convenient installation, etc.

Functions and features
● Front board three fixed installation, the cover is made of PC material which is transparent and anti-UV molded overall, the bottom of the meter and the terminal is made of bakelite material quality which is moisture-resistant, fire-retardant, high temperature molded overall. It has following features: good weatherability, high rigid, excellent dielectric strength, etc.
● May select 6+1 digits display (999999.1kWh, default) or 5+2 digits display, it can be arbitrary set by users from far infrared or port of RS485 data communication.
● Standard configuration one port of pulse output passive (polarity), May select increase a distant port of pulse output passive (nonpolarity). And contact with all kind of AMR system conveniently, Complying with standard IEC 62053-31 and DIN 43864.
● There are a port of far infrared data communication and a port of RS485 data communication. Standard configuration communication agreement complying with standard DL/T645-1997, can also choose any other communication agreement.
● Three LED instructions power supply state, signal of energy impulse and communication state.
● Automatic detection the direction of the flow of load current. And instructions by individual LED. (Only yellow energy impulse signal when working, that is meaning the direction of the flow of load current reverse).
● Single direction single component measure single phase two wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21.
● Direct connect operation, there are two types wiring you may select. Standard configuration type 1B wiring, may select type 1A wiring (Product Configuration code is BS).
● Standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is GC).
