III. Main features
High accuracy: with full electronic design, import specialized energy-metering chip, high sensitivity, exact measurement; accuracy is not influenced by frequency, temperature, voltage and high harmonics. The complete meter is not calibrated again after leaving factory.
High quality: Adopt SMT manufacturing processes and select international well-known brands, long life-cycle components to make sure the stable quality.
Lower power dissipation: the most optimized design to make power dissipaton be less than 3.0W. When used under wide range, the meter can reduce the power grid dissipaton and also improve effeciency of power supply.
Stable running: with good capability of anti-interference, strong capability of over-load and wide operating voltage,etc. All of these features can ensure higher stablity.
Data display: display accumulative power consumption and running status of all period of time and tariffs.
Data security: LCD displays various power consumption data and meter's status; when power off, internal data can be remained for 10 years; meter uses lithium battery as clock's back up power supply to ensure normal work for it.
Event record: store amount of total phase-failures, each phase-failure, total accumulative time of power failure, total accumulative time of each phase's power failure. The starting time and ending time of one latest time for phase failure and each phase failure can be remained.
Extensive function: on the terminal of meter is with pulse output and RS 485 interface, which can be applied to do programming and meter-reading; and through PC, the meter can realize the functions as infrared communication and time-calibration, program-setting, and meter-reading
IV Applicable scope
The meter is applied to all the enterprises customers, commercial customers and resident customers, etc, which has the necessity of time-shared measurement verified by power supply bureau. It can lead our users to optimize the method of using power electricity and improve efficiency of electricity consumption to optimize the electricity resource.
