Three-phase Smart Energy Meter (0.5S)

The electronic three-phase intelligent energy meter is designed and manufactured with advanced technology, utilizing large-scale integrated circuits, digital sampling processing technology, and SMT processes, tailored to the actual power consumption of industrial users. The meter's performance meets the technical requirements of 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 Multi-functional Energy Meters", DL/T 614-2007 "Multi-functional Energy Meters", Q/GDW 362-2009 "Technical Specification for Grade 1 Three-phase Fee-Controlled Intelligent Energy Meters", and Q/GDW 363-2009 "Technical Specification for Grade 1 Three-phase Intelligent Energy Meters". Its communication conforms to the requirements of DL/T 645-2007 "Communication Protocols for Multi-functional Meters".

Product Features

Embedded high-speed, high-precision AC voltage and current acquisition module, with high sampling accuracy and real-time electrical energy measurement.
The combination can measure active power electricity at different time intervals, including forward and reverse active power, reactive power, and four-quadrant reactive power electricity, and it is equipped with functions such as 485 communication and infrared communication.
Excellent electromagnetic compatibility, 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 power supply method); the electric meter can still operate normally when any two phases out of the four-phase three-wire system are disconnected.
In the event of a power loss to the communication power supply, the electric meter can retain data and maintain the operation of the clock chip.
Low power consumption.
