WS310 three phase energy meterCommercial application.Customization Service available.ISO, KEMA, MID, STS certified.
WS310, a multi-functional poly phase static electricity meter. It is developed under the ongoing technology evolution in the commercial & industrial sector and in order to meet the growing customer demand for static meters.It gives advantages to all users in the process: an installer, a maintenance engineer, a service engineer, a readout operator and a final user. The meter is approved and manufactured in compliance with the IEC 62052-11, IEC 62053-21 (IEC 61036) standards, and was designed according to even higher internal PAX standards.
Reliability and stability With proven electronic technology, long-life components and special care in the manufacturing process, WS310 guarantees precise accuracy and high reliability throughout its life span. Re-calibration is no longer necessary.
Fast and Easy Installation procedureThis design is easy to handle and extremely efficient for large-scale residential installations. Adapted to current connection standards the meter is compatible with existing installations and test benches.
Local metering data display (LCD): * Automatic Scroll mode * Manual scroll (by button) * Test mode (for utilities) Programmable data set and sequenceLCD back-light: optional LCD display when power absent: optional
Flexible Tariff ManagementBenefit from an internal RTC, full Time of Use (TOU) function is realized.
A tariff program is managed by the RTC which is suitable for the most complex metering applications.
The meter is able to generate “End of Period” information as defined by the user, usually based around billing dates.
The non-volatile memory is able to save energy information for up to 12 billing periods. This removes the need to visit the meter on a frequent basis.
WS310 supports 4 kinds of tariffs and 12 intervals in 24 hours for each day, which can be programmed flexibly. Interval 1 to 12 of each day can be combined with tariff 1 to 4 according to various requirements, this combination is called Tariff Set.
In addition, the meter supports holidays & weekends, which can be individually set with different kinds of combination of tariffs and intervals.
Maximum DemandMaximum Demand information can also be measured for all tariff rates allowing optimum billing of high consumption customers in particular.
Events log & Alarm-Over voltage and under voltage-Over current and under current-Reverse energy flow-Phase rotation -Demand overload-Low battery -Programm events -Open of terminal cover and meter cover-Occurrence of power on & off, -duration of back-up battery working
Anti-Tamper Features
-Measures the absolute sum of total and export energy-Optional abnormalities alarms &logs -Independent sealing of the meter body and terminal cover-Not programmable via keyboard
Load Profile
The meter has 2 load profile channels which can store optional data for up to 2M capacity. And the interval length can be set from 1 to 60 minutes.
Instantaneous Value
WS310 Measures all kinds of parameters:kW sum of phases and per phasekvar sum of phases and per phasekVA sum of phases and per phaseFrequency per phasePower factorCurrent per phaseVoltage per phase
Freezing Function
The meter has optional function to freeze appointed variable parameters at the appointed time. Operators can read out these parameters to analyze.
Self-diagnostic
Meter parameters need to be set for the first time usage when out of factory. Instead, LCD will have an indication if the parameters are not integratedMeter will check the hardware operating well every time when power on again, and will alarm for accidental faults.
Full functional PC software
Running under Microsoft Windows environmentFull reading and setting function via optical port or Rs485 port.Three security levels for operators: - administrator - setting & reading - reading onlyPrinted the programmed parameters selected by userData output & analysis
