Three-phase Smart Energy Meter (0.5S)

The electronic three-phase intelligent energy meter is a modern, advanced-level instrument designed and manufactured with large-scale integrated circuits, digital sampling processing technology, and SMT processes, based on the actual power consumption status of industrial users. The meter's performance indicators comply with the technical requirements for multifunctional energy meters set forth in the following standards: GB/T 17215.323-2008 "Special Requirements for AC Measuring Equipment - Part 23: Static Reactive Energy Meters (2nd and 3rd Grades)", GB/T 17215.321-2008 "Special Requirements for AC Measuring Equipment - Part 21: Static Active Energy Meters (1st and 2nd Grades)", GB/T 17215.301-2007 "Special Requirements for Multifunctional Energy Meters", DL/T 614-2007 "Multifunctional Energy Meters", Q/GDW 362-2009 "Technical Specification for Grade 1 Three-Phase Energy Control Intelligent Energy Meters", and Q/GDW 363-2009 "Technical Specification for Grade 1 Three-Phase Intelligent Energy Meters". Its communication meets the requirements of DL/T 645-2007 "Communication Protocols for Multifunctional Meters".

Product Features

Integrated high-speed, high-precision AC voltage and current sampling module, with high sampling accuracy and real-time electrical energy measurement.
The product can measure split-time active power, forward and reverse active power, reactive power, four-quadrant reactive power, and is equipped with 485 communication and infrared communication functions.
Excellent electromagnetic compatibility performance, capable of withstanding interference from high-voltage spikes, strong magnetic fields, strong static electricity, lightning surges, and possesses strong temperature adaptive capabilities.
Three-phase power supply (i.e., line supply method); the electrical meter can still operate normally when any two phases in the three-phase four-wire system are disconnected.
In the event of a power loss to the communication power supply, the electrical energy meter can retain data and maintain the operation of the clock chip.
Low power consumption.
