APPLICATION

EM051AO SINGLE PHASE ELECTRONIC FRONT BOARD INSTALLED MULTIFUNCTIONAL ACTIVE ENERGY METER

Application
Model EM051AO single phase four wire electronic multifunctional front board installed energy meter is a kind of new style single phase multifunctional energy meter. The meter completely accord with relevant technical requirements of class 1 single phase active energy meter stipulated in international standard IEC 62053-21 and class 2 single phase reactive energy meter in international standard IEC 62053-23. It can accurately and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net, This meter has LCD monitors shows the active energy power 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 holes installation, the cover is made of PC material which is transparent and anti-UV molded overall, the base of the meter and the terminal block is made of quality bakelite material which is moisture-resistant, fire-retardant, high temperature molded overall. It has following features: good weather ability, high rigid, good insulation performance, etc.
● Three tariffs, gou may select 12 daily period of times. You can set the date which can automatic read the meter every month. May select single tariff function in weekend. (Please specified when ordering).
● There is a clock and Maintenance-free backup lithium batteries in it. Battery capacity detection and display all the time. It can keep the electricity data for 12 months. The data can be kept forever after power cut off.
● May select cycle display (default) or push the button itemized display, it can display 14 data at most. Can select the data which displayed. The decimal median which displayed can choose set one or two.
● A port of pulse output passive (polarity), complying with standard IEC 62053-31.
● There are far infrared and a port of RS485 communication data. It is use for setting and reading the meter. Set and operation have password protection, communication protelot complying with standard DL/T645-1997.
● LED instructions respectively power state, signal of power impulse, the direction of the trend of load current, and the data communications state.
● Detect active and reactive energy, active and reactive power, voltage, current and frequency, etc. of single phase two wire forward and reverse. Complying with standard IEC 62053-21 and IEC 62053-23..
● Direct connect and use, there are two types you may select. Standard configuration type 1A connection, may select type 1B connection (Product Configuration code is AM).
● Standard configuration extended terminals cover, may select short terminals cover, in order to protect to use electricity safely. (Product Configuration code is AN).
