▷Product Overview
The power meter is the use of appl ication specific integrated circuit, the latest
micro-electronics technology and SMT process design made of high-tech
products. The table has a power ful ant i -elect romagnet ic inter ference
performance, wide operating voltage range, high rel iabi l ity, long l ife, high
accuracy, low power consumption, electricity steal ing and so on.
Part of the table using ADE7755 energy metering chip for measuring rated
frequency 50Hz single-phase AC active electric energy, through the acquisition
of voltage and current loop signals wi l l be converted into the corresponding
energy value of energy pulse signal, the control chip, programmed according to
the user good time, the pulses of electricity at different times, respectively, the
corresponding rates recorded in and complete the display and communication
functions in order to achieve multiple rate metering functions.
This product can be used HHU through infrared remote control programming,
meter reading; or using RS485 communication interface with the micro-computer
communication; the same time, the table also has a radio, when the school
functions, for the automatic management of electricity power sector to provide a
more convenient services.
The products meet the IEC 62053-21,IEC 62052-11 standard for electronic
energy meter of the relevant technical requirements.

green disposable l ithium batteries;
●you can set the table number, bureau number, hours, rates, date, time, automatic
meter reading, password, display items and start recycling capacity;
● with back-up battery voltage test instructions, hardware, meter status, meter
communications state, the clock status, power orientation, school status, and
the current time when the meter is running the state and other state
identification bit, and can be read via RS485 or handheld computers.
