Product Description
CE Certified EM4373 Lora LoraWAN Electricity Meter Three Phase Power Quality Analyzer Rs485 Modbus
Overview:
The EM4373 power quality analyzer meter is a standard four-module 72mm width, which can be used for single-phase two-wire/three-phase three-wire/three-phase four-wire power grids.The instrument provides real-time monitoring of A/B/C three phase Voltage(L-N,L-L), Amp, kW, kVA, kvar, PF, include maximum, minimum, average values. Phase angle, voltage phase sequence indications and Voltage asymmetry & current asymmetry. PT ratio& CT ratio selectable, THD up to 41th order for voltage& current and Maximum demand on Amp & kW& kVA.
EM4373 is installed in the solar inverter scenario. By linking a LoRa serial protocol converter to the inverter side via RS-485, the anti-islanding function can be achieved. The LoRa serial protocol converter periodically polls, collects data from EM4373, and analyzes and processes it in real-time for anti-islanding monitoring, preventing excess photovoltaic power generation from being fed into the grid.
Featuring plug-and-play technology, the EM4373 supports external split-core CTs or Rogowski coils with RJ45 connectors. This enables live-line installation, significantly boosting on-site efficiency.
LoraWan optional ,frequency band include EU868,AS923/CN433/CN470/AU915/US902 MHz, etc
