Basic function
1. Metering function:It can measure real-time parameters of three-phase meter such as voltage, current, power, frequency, phase angle power factor etc., and it has measurement function with high precision of positive and negative active energy.
2. Display:LCD
3. Alarm detection:It has error detection alarm function of over voltage, over current, loss of phase, reverse phase sequence, battery without electricity and so on.
4. Historic information log: It has the function of freezing data and supplement frozen data. Demands calculation and load curve record once half hour for 180 days.
5. Communication:It has remote communication(changeable PLC. RF. GPRS etc.,), RS485 and various others communication method.
6. Multi-tariff metering function:it has time-sharing four rates measurement, and has time-sharing function of 120 holidays, four standby periods, 6 week tables, 6 day period tables, 16 periods per day.
7. Others functions:It has frequency and occurrence time records of power on, power down, programming, modification time and PTCT.
Application range
It can be applied to the broad masses of urban and rural users in terms of three phase time-sharing pricing.
