This multi function Din rail Mounted meter is use of advanced energy metering chip, multi-rate application of digital sampling technology and SMT technology, based on people's actual electricity situation designed.
It has achieve timemeasurement, set autosave data time, handheld terminal or PC programming and reading.
The meter has four rates(T1,T2,T3,T4), 10 period, four time zones, power test pulse output maximum demand and reactive power consumption.
Main Functions
1 . Measurement
-Time-measuring positive/reverse active energy; positive/reverse reactive energy and store its data.
-Total electric energy, sharp(T1), peak(T2), flat(T3), valley(T4) were accumulate and save.
- Communication,time switch,repeated power outages will not affect measurement accuracy.
-Meter stored within 12 months historical active and reactive energy consumption data.
- Data will not lost, and can keep for more than 10 years
2. Display Function
- Electric energy shows six integers, and two decimal .
-Auto rolling display function with parameters, round time interval 5 seconds
3 . Communication
--RS485 interface and internal meter is isolated, also design of lightning protection circuitry.
-The communication protocol with reference MODBUS-RTU Statute.
4. Output Function
-Active pulse output test function (pulse width 80ms ± 20ms).
-with RS485 output function, can be realized RS485 centralized meter reading.
5.Event logging
- Recorded present and last 2 month total maximum active demand, and time occurrence.
