Product Description
This Meter is used to measure 50Hz AC active energy and the power flow of peak time, flat time and off-peak time. Its functions comply with the corresponding technical requirements for the Class 1 Single-phase Watt-hour Meter and its data communication protocols obey the IEC standards.The features of this meter are: long service life, high accuracy class, high overload, low power consumption and small size.
Total Energy
A. Measure total amount of forward active, reverse active energy and restore the data, which are indicated by LED
B. The screen of LCD will display 'reverse' when power reverse.
C. Measure reverse active energy separately
Measuring multi-tariff in different time internals
The meter has 4 kinds of tariff defined as sharp, peak, shoulder and off-peak. The meter can be programmed as single tariff, double tariff and three-tariff or four-tariff. During each tariff interval, the meter can measure forward/reverse active energy.
Tariff and Time Intervals
The meter has 12 programmable interval tables, of which each can set up to 12 intervals assharp, peak, shoulder and off-peak during 24 hours.
The minimum unit of each tariff interval can be set up as 1 minute.
The meter can automatically switch calendar, time and leap year.
Measuring real- time powerMeasure real-time power through pulse constant and pulse interval.
The function of data-transfer
The meter can transfer data automatically on the reading date( 1st to 27th are programmable ).That is the transfer of total forward/ reverse active energy.The meter can store the data in the previous 12 months and store the data for 10 years at power failing.
Recording reverse energy
The meter can record the total time of reverse energy and the last time period of reverse energy.
Meter programmingThe meter can restore the times of programming and the latest programming time.
Remote control function
The meter has the function of remote control through RS-485.
