Description Energy Monitoring: Measures and calculates the energy consumption and cost of your connected devices. A total of 7 monitoring modes, this outlet power meter supports monitoring time, power, cost, accumulated energy consumption, voltage, frequency, current, power factor, minimum power, maximum power, and electricity price. Overvoltage Protection: Electrical voltage: 230V AC 50Hz, maximum current: 16 amps, maximum power: 3680 W. When the total power exceeds the rated power of 3680 W for the outlet power meter, 'Overload' will flash on the screen to warn you to disconnect the device from the power grid to avoid overheating. Easy to Use: Simply press the FVNC button on the outlet power meter to select the monitoring mode, the COST button to adjust the device's electricity price, the UP and DOWN buttons to adjust the price. The RESET button clears all settings. With dual-rate mode, you can set two targets simultaneously to calculate and compare electricity costs at different times. Various Parameter Measurements: With a variety of measurement parameters such as power (W), energy (kWh), voltage (V), current, power factor, cost, as well as minimum and maximum power, this energy cost meter gives you the most basic information about your household electricity. Measures and calculates energy consumption (0.00 - 9999.9 kWh), active power (0.1 - 3680 Watts), mains voltage (200 - 276 Volts), and energy costs (0.00 - 99.99), easy to read and record data. Versatile Use: Easily calculate the energy consumption of devices. Suitable for many electrical appliances: bread maker, coffee maker, computer, game consoles, printer, TV, Hi-Fi, DVD, heater, Blu-ray player, oven, etc.
