Product Description

Main Functional Features:
1. Power measurement functions
2. Demand Measurement
3. Display
4. Clock, time interval and rate function
5. Measuring and monitoring
6. Freezing function
1) Timing freeze:
2) Agreed to freeze: In the old and new rates / time interval conversion, stepped price change or the power company that has special requirements, agreed to freeze moments of power and other important data.
3) Daily freeze: Store energy consumption of the hour of 0: 00 per day; Can store 2 months data.
4) The contents of freezing and the identifiers conform to DL / T 645-2007 and the recorded documentation requirements.

7. Load Records
1). Load recorded contents can be combined freely as per DL / T 645-2007 six types of definitions, which includes "voltage, current, frequency, " "active and reactive power, " "power factor", " the total active and reactive power, " "quadrant reactive total power, "and " Current Demand ".
2). Load recorded interval setting in 1 ~ 60min range, the time interval of each type load record can be the same or be different.
3). Beside recording the total forwarding and reverse active energy, the total reactive energy, the quadrant total reactive energy, the load storage space can keep the data capacity of not less than 40 days under circumstances of the time interval of 1 min.

8. Blackout meter reading:
Under the power failure condition, to activate energy meter by means of pressing button or non-contact and read meter energy.

9. Data storage function
1) can store the total two-way energy at least 12 balance sheet date and the energy data of each rate; The data transfer dividing time is 24: 00 of the end of the month (for 0: 00 of the beginning of the month) or on the hour of 1 to 28 days in the month.
2) Can store the two-way maximum demand at least 12 balance sheet date, maximum demand of each rate and the occurrence date and time data; The data transfer dividing time is 24: 00 of the end of the month (for 0: 00 of the beginning of the month) or on the hour of 1 to 28 days in the month. While data transfer at the end of the month, the maximum demand value of this month automatically resumes to zero, the maximum demand value of other moments is not transferred to store.
3) Energy meter power loss, the storage time of all relevant data with the settlement is not less than 10 years, and other data hold time no less than 3 years.
Clear: Energy meter clear operation as a permanent record of the incident; All clear instructions to prevent unauthorized person to operate with security measures, such as installing hardware programming switch, operation password, or sealing management and keep the data before clearance.

10. Communication function
1) Energy meter with one infrared communication interface and one RS485 communication interface. The Infrared and RS485 communication interface physical layer independent.
2) RS485 interface communication baud rate can be flexibly set, the standard rate of 1200bps, 2400bps, 4800bps, 9600bps, the default is 2400bps.
3) RS485, infrared and other communications to follow DL / T 645-2007 and the recorded documents.
4) Support to modify the rate period and price by infrared and RS485 communication interface, and to prevent unauthorized person to operate with security measures, such as installing hardware programming switch, operation password, or sealing management and keep the data before clearance.

11. Pulse output
Arbitrary voltage loss, phase off occurred, the power meter to record and send the right message.
Load switch can be set according to need - internal or external.
