2) Accuracy: active Class 0.2, 0.5, 1.0, and reactive Class 2.0
3) Reference voltage: 3 x (220 / 380V, 57.7 / 100V, 100V)
4) Rated current: 3 x 0.3 (1.2)A, 3 x 1.5 (6)A, 3 x 5 (6)A, 3 x 5 (10)A
5) Power loss: ≤1.5W
6) Deviation of RTC: ≤0.5s/D (23±3°C)
7) Backup lithium battery working life: >10 years, Continuous working time: >3 years
8) Display: LCD display

Main functions:
1) Measures accurately the forward / reverse active power respectively, calculates the
energy in different directions, solves the problems of energy tamper caused by
connecting current in reverse
2) Measures multi-tariff (peak, shoulder, trough) active energy and demand, and also
measures total reactive energy
3) Adopts public GPRS communication methods, which avoid the investment for the
communication circuitry and for maintaining the circuitry
4) With infrared communication interface, which is used to set and read the
parameters of the meter
5) Measures and records the accumulative time of each phase's voltage loss, and
after power off, all stored data can maintain over ten years
6) Monitoring function: if there appears any abnormal condition, it will alarm to the
monitoring center by short message and data transmission
7) Adopts LCD display: can show six integers and two decimals
8) Recycling display modes: can set display items by infrared handhold meter-reading
device
9) Data intellectual collecting function: can send all kinds of data which electric meter
can send out to center station by GPRS. When there appears any abnormal
condition for the big users, the system can send alarming information to the center
station software or the appointed GSM mobile phone by short message and GPRS
10) The frozen and transferred time of the electric energy data is any specified hour
among 0-23 of each day
11) The frozen and transferred date of the electric energy data is any hour in any
specified day among 1-28 of each month
12) Adopts advanced non-error digital communication methods, which avoid data loss
and error code during communication, and the module's maximum communicating
speed is 115,200bps
13) Low running expense
