Suitable for power plants, substations, and various enterprises and institutions that require high reliability and high stability electricity metering. Details inquiry:
This electric energy meter adopts high-performance metering chips, with high accuracy in small current measurement, small temperature and frequency variation, stable performance, rich functions, and strong anti-interference ability. It is carefully designed in terms of easy operation, self checking and error correction, data security, and analysis of abnormal electricity consumption, and supports AC/DC adaptive auxiliary power supply. It adopts a fully sealed structure and shell, which can meet the requirements of harsh high and low temperature alternating humid and hot environments.
● Supports dual RS-485 and far-infrared communication;
Time division metering of active and reactive energy, capable of storing 13 months of historical electricity data.
Record the maximum demand and occurrence time.
Maximum 8 rates, supporting switching between current and backup rate periods;
● Multiple backup storage of key data such as battery level and clock, with self checking and error correction functions;
● It can record six types of load curve data, including voltage, current, and electricity;
Comprehensive and rich event records, equipped with strong magnetic field detection, lid opening detection and other anti-theft electricity monitoring and recording;
● Equipped with sound, light, and auxiliary terminal alarm prompt functions for power grid abnormalities and meter faults;
After a power outage, the display can be awakened through buttons or handheld devices, and far-infrared meter reading is possible;
AC/DC adaptive auxiliary power supply, with priority given to the auxiliary power supply after power on.
