This Meter is used to measure 50Hz AC active energy and the power flow of peak time, flat time and off-peak time.
The power of real time clock chip is supplied with large capacity lithium battery to ensure the high accuracy of the time switch. And its standard infrared communication port finishes the function of setting, clock setting, tariff setting and period program. Etc.
1. Measurement of electrical parameters as voltage, current and power
Measure and display the instantaneous effetive value of phase voltage and phase current in phase A, B and C.
Measure and display the instantaneous power magnitude of active and reactive and the total active and reactive in phase A, B and C.
Measureand display the instantaneous power factor of the total three phases and each individual phase.
Measure and display the instantaneous frequency of the power grid.
2. Meter Event Recording
Detection and recording of cover opening, timing recording, programming event recording, maximum demand recording, time zone modifying recording, power purchasing recording, alarm recording and emergency alarm recording.
3. Power Grid Event Recording
Voltage loss recording, current loss recording, voltage failure recording, phase failure recording, unbalanced voltage recording and unbalanced current recording.
4. Power Freezing
Monthly freezing, daily freezing, hourly freezing and instantaneous freezing
5. Load control Function
Overload disconnection control, programmable threshold of load and maximum overload disconnection times.
6. Load Curve Recording Function
Scroll displays records of sampling data by user's schedule;configures and reads the load curve.
7.RS-485 and Infrared Communication
Builds in RS485 port and modulated Infrared port. To configure timing, meter parameters, meter address, baud rate, to read meter data, change communication password, to proceed overall reset, maximum demand reset and broadcast freezing power quantity with a communicable modulated-Infrared HHU.
8. Security Management Function
All programmes(excepts communication address, baud rate, timing broadcast or freezing) can only proceeded under the permission status. Builds with a three-level password protection and automatic wrong password lock-down mechanism.
