230V Single Phase Smart Electric Meter for Automatic Remote Reading System
2. Remote Fee Control
It finished parameter setting and remote purchasing through RS485, carrier and other virtual medium..
2.1 Remote Fee Control Electricity Meter
The calculative process for electricity is finished in remote system, there is no relative information such as electricity fee have been stored or displayed in meter. Meter has to pass strict password authentication and safe certification since getting remote commands such as switch out, switch on, ESAM data reading.
2.2 Encryption required for safe certification
To make sure the reliable and safe data transportation, the commands from meter through solid or virtual medium have to pass strict password authentication or safe certification such as ESAM module.
3. Measuring and Monitoring
It can measure and monitor operating parameter such as voltage, current (including zero line current), power, power factor and etc. The error would not exceed ±1%
4. Event Log
--Alarm Red, it is off in normal condition, and would be on when alarming
--Trip Yellow, it is off in normal condition, and would be on when load switch disconnect.
When the following faults or alarm appear, LCD would stop on the certain code and backlight keep on.
7 . Timing
Build in clock circuit with temperature compensation function, the calendar, timing, leap year can be changed over automatically. The output frequency for inner clock terminal is 1Hz. Between -25℃ to +60℃, clock accuracy is no more than ±1 s/d; Under reference temperature 23℃, clock accuracy is no more than ±0.5 s/d.
The accepted time broadcasting is no more than 5 min. No need to match with programming switch and communication password when time broadcasting. It can be set according to the inquire, and it avoid from handling in 5 min at the time when freezing or data storing.
9. Load Switch
External load switch, there is a group of switch signal for meter output. Volume of switch point is AC 220V/2A. Under normal condition, switch signal for output should keep switch on of load switch, allow for power on; When reach certain condition, switch signal for output should drive operation for external load switch, power off.
10. Pulse Output
Meter has function for LED pulse and electrical pulse output which comes direct ratio with measuring energy. Optical test output device should comply gb/t17215.211-2006, electricity test output device should comply GB/T15284-2002. It has signal output terminal for clock, and the output frequency is 1Hz
