WiFi Single-Phase Energy Meter, AC 40-300V 100A Electric Meter, 1-Phase Wattmeter, DIN Rail Meter, Watt/kWh Voltmeter/Ammeter with LCD Display, Suitable for Power Measurement

【WiFi control function】The digital Wi-Fi meter is made of high-quality, flame-retardant ABS material and a high-precision chip, with a measurement accuracy of ±1%. The AC meter is safe to use, highly accurate, and stable. The upgraded version adds a Wi-Fi control function, allowing for intelligent control via the Graffiti app. Data can be monitored remotely in real time, enabling you to better manage your electricity consumption, use electricity responsibly, and live a low-carbon life.【six-in-one universal power meter】Energy meters, a real-time display interface: voltage: 40-300V, current: 0-100A, power: 0-30000W, energy consumption: 0-99.999kWh, frequency: 45-65Hz, power factor: 0-1PF and six other measurement parameters; single-phase DIN rail power meter, so your electricity consumption is transparent throughout your life (Note: this product can only measure active power, so power is calculated as voltage * current * power factor (V * A * PF))【LED color screen】The energy meter's HD color LCD screen, with a 178° viewing angle and no blind spots, and backlighting, ensures that real-time wattmeter data from the electricity meter is clearly visible day or night.【Multi-functional】1. Data Reset: This single-phase electric meter meets a variety of measurement needs. Press the reset button for five seconds to reset the rail on the top cover of the digital energy meter. 2. When the device is switched off or there is an accidental power outage, the energy value will be saved automatically. The data will continue to be saved after power is restored to measure the voltage.【Widely used】The DIN rail-type energy meter is easy to install, compact, and space-saving, widely used in electrical power measurement systems, schools, markets, household appliances, industry, laboratories, etc. (Note: The wattmeter can only be used to measure AC current from 45 to 65 Hz in urban areas). The multimeter will be damaged if used to measure non-standard square waves and sine waves.
