Linyang Multi-tariff Single Phase electronic energy meter is developed by Linyang as a new type of energy measurement products, using LSI SMT technology, with modern advanced level in line with international norms.
It has the following features as below:
- To measure total energy, each tariff’s energy, and the positive and negative energy.
- To configure TOU tariff, including day table, seasonal table, week table, holidays, etc.
- To measure instantaneous values, including voltage, current, frequency, power, power factor.
- To record events, including open cover / cap, power up / power down, programming, etc.
- To record alarm and status information or display them on the LCD.
- To record 16-month history of electricity, load profile, maximum demand.
- To communicate with optical port or RS485 port.
TOU Tariff
- Support 4 tariff rates, 8 switch times.
- Support 28 day tables.
- Support 50 holidays’ or special days’ tariff configuration.
- Support working-day table, week table, time-zone table to be configurable.
Clock RTC Function
1) using the built-in hardware clock circuit with temperature compensation function;
2) clock having a local calendar, chronograph, automatic leap year conversion.
3) using SAFT LS14250 Li-SOCI2 battery as the clock auxiliary power; ≥15 years of battery life, battery voltage and battery life can be inquired. When the battery voltage was low, the undervoltage alarm would be given. Under the conditions of permission allowing the battery could be replaced (under the conditions when the cover is sealed).
Event Record Function
1) Programming records: Record the times of programming, each programming time, and keeping the last nine event records.
2) Power-down records: Record the total times of power outages, blackouts and recalls time, and keeping the last 21 times’ event log.
3) Clear maximum demand records: Record MD times of clearance, and the last time.
4) Open the cover and terminal cover records: Record the times of Open the cover and terminal cover, the accurate time of open cover and open terminal cover, and keeping recent 30 records occurred.
Load profile
Data items of load profile:
1) Status bit of on-site modification time
2) Status bit of remote modification time
3) Status bit of on-site programming
4) Status bit of Remote Programming
5) Status bit of Power-down
6) Status bit of Power Reverse
7) Status bit of Open Cover
8) Incremental electricity
Note: Electricity incremental data and event status information will be stored across 75 days per 30-minute interval. Load profile to be read by two instructions: read of full-data and read of specified time-period
Communication Port
- Optical Port, Communication Protocol with IEC 62056-21 Mode C.
- RS485 Port, Communication Protocol with IEC 62056-21 Mode C.
