4G+ Bluetooth Rail-Mounted Electric Meter

It measures total active energy in both forward and reverse directions, energy by tariff, and reactive energy across all four quadrants. It features a maximum demand recording function for both active and reactive power, and performs real-time measurement and processing of electrical parameters such as active and reactive power, voltage, current, power factor, and frequency. Additionally, it offers time-of-use metering, automatic meter reading, data storage for energy consumption and demand, load‑profile recording, and event‑data logging. This series of electric meters employs an ultra‑large‑scale digital signal processing chip, a fully isolated standard RS‑485 communication interface, Bluetooth connectivity, and 4G communication.

Multifunctional Power Meter

It can measure three-phase voltage, current, power, frequency, power factor, electrical energy, voltage and current unbalance, average voltage, phase-to-phase voltage angle, 2nd to 63rd harmonic components of voltage and current, total harmonic distortion, maximum/minimum values of voltage and current, five tariff rates across two time zones with eight time periods, active/reactive maximum demand, residual (or zero-sequence) current, and up to 32 switch‑state SOE event records. Optional configurations include 4 digital inputs, 4 digital outputs, 4 analog outputs, two RS‑485 communication ports, Ethernet communication, six wired temperature‑sensing channels, and wireless temperature‑sensing functionality. Available in five standard sizes: 120 mm, 96 mm, 72 mm, 80 mm, and 48 mm.
