What are the functions and features of three phase digital voltage bidirectional electric meter?

Gomelong is a professional manufactures of Three phase digital voltage bidirectional electric meters. Our professional expertise in manufacturing Three phase digital voltage bidirectional electric meters has been honed over the past 10+ years. Three Phase Digital Voltage Bidirectional Electric Meters are a kind of new style three phase four wire multifunction energy meter.The meter completely accord with relevant technical requirements of class 1 three phase active energy meter stipulated in international standard IEC 62053-21 and class1 three phase reactive energy meter in international standard IEC 62053-23.

Features of Three Phase Digital Voltage Bidirectional Electric Meters:
♦ Measurement of Import/Export active energy, current energy balance, Instant voltage/current/power

♦ PLC, Rs485, Infrared interface

♦ Event record: Cover open detection, Reverse current, Fraud

The three phase digital voltage bidirectional electric meter can be selected through software programming to meet the needs of different users. Can choose photoelectric communication or infrared communication, can expand the cover recording function.

※ Time-sharing counting of active and reactive electric quantity, and can store the electric quantity data for at least three months, with midline current measurement.

※ With 4 rates, 10 time periods.

※ It has the function of time zone end freezing, zero point and instant power freezing, and the power consumption settlement function from January to December.

※ External clock chip, high precision, stable operation, and can compensate the humidity of the dry clock through the temperature measuring core.

※ With wheel display and key display function, the maximum can be 32 wheel display 64 key display data, with up and down page query function, through the remote control can arbitrarily view the display of data items.

※ Can be awakened in the blackout state through two ways: key, infrared.

※ It can communicate with the meter through RS485 (double RS485) and infrared communication interface, realizing the simultaneous communication of three parties without interference.

※ With positive and negative active power, reactive power (motion) pulse output, can meet the needs of different users.

※ Multi-function multi-outlet, 1Hz clock signal and demand cycle replacement signal, time switch signal output can be achieved by setting.

※ With power outage abnormal current detection function, can prevent out-of-body power and easy to recharge.

※ Can realize manual and automatic demand zero, and has the load representative daily record.

※ It is possible to monitor the abnormal operation of the meter through the alarm light and alarm conformity.

※ With voltage loss, loss of current, power failure, power failure, demand zero, programming, broadcast time correction, battery running time and other event records, with time standard, and voltage qualified rate, current unbalance rate, monthly power supply reliability rate, power rezero records.

※ The meter has backlight function, and has a variety of backlight wake-up mode, which is convenient to view the data in low-light places.

※ With load curve recording function, can be extended up to 356K bytes.
