Multi-Function Poly Phase Kwh Meter

Measuring instantaneous voltage, current, power and frequency of the phases;
Record function of voltage-loss (phase failure), current-loss, voltage eligible rate, electric break and restore, programming, maximum demand clearing, broadcast time synchronization and so on;
Measuring import and export active energy (TOU); Measuring positive and negative reactive energy (TOU); even export and import reactive energy can be defined and recorded accordingly;
Measuring Maximum Demand of positive active/reactive, negative active/reactive
(TOU);
Power supply quality monitor; to detect and record events of phase voltage lose, phase current lose, unqualified voltage sag, power outrage, programming
parameterization (broadcast time calibration, reset etc.,)
Maximum programming 4 tariffs, 16 day tables, 4 season year tables and 12 holiday tables;
LCD display with 6 integers and 2 decimals;
Detection of LCD display segment, operating status, battery consume and memory alarm
For the program of important parameterization, controlled by password and internal hardware switch;
Automatic scroll display with quick scan function; maximum 36 scroll display items can be set freely as well as display sequence and interval time;
Built-in RTC clock, broadcast time synchronization via RS485 communication interface;
Going to sleep-mode while power outrage; during power failure it can be waken up by pressing Button or infrared HHU to transfer data from meter to HHU or PC with the support of backup battery;
Fast and Convenient replacement of backup battery without removing the upper
cover;
Provided with 2 RS485 port (optional) and 1 optical port; it can communicate with PC or HHU via two RS485 ports and optical port in the meantime;
Baud rate: RS485 port 1: 1200bps~960bps; RS486 port 2: 1200bps;
Expand functionalities (option); Load profile, frozen energy consumption data, detection of current even during power failure;
