Power Meter Electricity Usage Monitor 8 Modes, Energy Monitor Plug with LCD Backlight Overload Sound Alarm.Energy Meter Power Consumption Monitors Socket KWH Amp Volt Watt Monitoring Meter Plug

Comprehensive monitoring of energy.
Safety with overload protection.
Data retention for convenience.

Main Highlights

[Various Monitoring Parameters] The energy monitor can monitor the power (W), energy (kWh), volts, amps, hertz, power factor, cost,minimum and maximum power (W), cumulative days and time of your appliances. By switching 8 display modes, you can easily know the various parameters while the appliance is working. These power monitors can also calculate and display how much power your appliance uses and how much electricity bill it cost in cumulative time for energy saving
[Overload Protection] The default overload of the energy monitor plug is 2900W. When the power of the appliance exceeds the overload power, the LCD will display "OVERLOAD" and emit a "beep" sound to warn the user. All the buttons of wattage meter will quit working and can only work again when the overload alarm has been cleared by raising the setting value or removing the appliances
[Data Memory Function] The energy monitor will record your power consumption data when you remove electric meter from socket, or remove appliances from the power meter. All setting data and cumulative data(electricity quantity, cost, unit price) will be saved. You can directly see the last data when you use the electricity usage monitor next time(NOT including current, voltage, power, power factors). This function can also automatically save the data when there is a sudden power failure
[KWH Alarm Settings] You can set a power consumption limit, and when the accumulated power consumption reaches the set value, the energy monitoring plug uk will emit a "beep" sound, and the "KWH" alarm will flash continuously to alert the user. If you want to silence the alarm, you can set a higher power consumption limit or reset the power consumption limit (Note: resetting will clear all settings)
[Adjustable Backlight Time] Our watt meter has 5 options of backlight time. The default backlight time duration is 10 minutes(bL-0). If you want to change the backlight time, you can press and hold "UP" and "DOWN" button at the same time to enter backlight time setting, then press "UP" and "DOWN" to select the backlight time (bL-0 =10 minutes, bL-1=1 hour, bL-2=4 hours, bL-3=8 hours, bL-4=normally on), finally press the "SET" to save the backlight time settings
[Backlight Display] With white backlight and black digits, the LCD display of our power monitor plug uk can display the data clearer and help you to read the data easier no matter day or night. The backlight will only lights up when the power meter plug is connected to AC power. You can set the time for the screen to turn off automatically, or press the "DOWN" button to manually turn on and off the backlight
[Premium Material] The whole body of our power consumption plug is made of high-quality PC material, which makes our energy meter monitor more long lasting. The standard DE socket and plug is suitable for all DE standard appliances

Press + to display Watt (active power) and VA (apparent Power). Press OK to display true RMS voltage Vrms and true RMS current Arms. Press - to display Hz (frequency) and PF (power factor). Press ↺ to display the maximum and minimum power. Press OK for 3s to display the complete accumulated time.
【Multiple protection】When the load power exceed the overload setting value, power consumption exceed KWH alarm setting value, electricity cost exceed cost alarm setting value, LCD displays "Overload", "KWh ALARM" or "COST ALARM" and LED light flashes continuously to warn user. The default overload power is 3680W (0~3680W adjustable). In general, you need to set the overload power to 2900W before using. Ideal for monitoring the energy consumption of household appliances.
【Data storage】This power meter UK plug has a built-in high-precision chip that stores data in the event of a power failure. It has a reset function and a function to delete measurement data but retain setting parameters for switching between multiple appliances. It can effectively monitor the electricity consumption, reduce electricity bills and save energy.
【Upgraded LCD display】Wide viewing angles is great for reading and recording the data in any angles. No need to stand on the front of the display and bend over to read the numbers, especially if the energy monitor plug is not at eye level, or is only viewable from an angle. Note: No backlight.
