It can control three single-phase circuits, or a three-phase circuit. And each phase can be controlled independently.
1.General Description
Static three circuit single phase two wire energy meter for measure AC active energy and variable parameter adopt advanced large-scale integrated circuit IC and SMT manufacturing technology. They have following features: bi-directional energy measurement , wide voltage , anti-tamper , high accuracy and reliability , large overload, ow self-consumption , small volume , light weight. The meter have RS485 communication port,can realize remote reading .
The meter should be installed in suitable environment with ambient temperature rang between -25℃-+55℃,the relative humidity less than 75% and temperature limits between -40℃-+70℃.
The meter is manufactured complying with international standard EC62052-11 on "Electricity metering equipment (AC) General requirements tests and test conditions" and IEC62053-21 on "Static meters for active energy(classes 1 and 2)".
2.Basic Function
Measuring three circuit single phase positive & negative active energy separately, LCD display with backlight.
The meter LCD also display three circuit single phase real voltage , current , active power , reactive power, power factor.
APP can display three circuit single phase positive active energy , reverse active energy and real parameter and remote control on/off.
Hour/Day/Month/Year history active energy consumption tracking by APP, and also can output excel records by email.
Over voltage and under voltage protection which can set by APP, Each protection function can be opened/closed as customer requirement
Current protection which can set by APP for three circuit each phase separately
Alarm event records and on/off operation records on APP for three circuit each phase separately
Prepayment function if balance energy used up. It will cut off automatic. This function can be opened/closed by APP for three circuit each phase separately
Energy data can store on memory chip when power off, it also still measure energy when lose WIFI connection and it will update the energy on APP when connect WIFI again
