Description Energy monitoring: measuring and calculating the energy consumption and the cost of your connected devices. Total 7 monitoring modes, this power meter for socket supports monitoring time, power, costs, accumulated power 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 of the power meter for socket, Overload flashes on the screen to warn you that the device needs to be disconnected from the mains to avoid overheating. Easy to use: simply press the FVNC button from the power meter for socket to select the monitoring mode, the COST button to adjust the power price of the unit, the UP and DOWN buttons to adjust the price. RESET button to delete all settings. With dual rate mode, you can set two targets at the same time to calculate and compare the electricity costs at different times. Various parameter measurement: with a variety of measuring parameters such as power (W), energy (KWh), voltage (V), current, power factor, cost as well as minimal and maximum power, this energy cost meter socket provides you with the most basic data about your household power. Measures and calculates energy consumption (0.00 - 9,999.9 kWh), active power (0.1 - 3,680 Watt), mains voltage (200 - 276 Volt) and energy costs (0.00 - 99.99 ), easy to read and record data. Versatile use: simply calculate the energy consumption of devices. Suitable for many electrical appliances, bread machine, coffee machine, computer, game consoles, printer, TV, Hi-Fi, DVD, fan heater, Blu-ray player, oven, etc.
