EM20-ER with free external relay and transformer /electricity meter energy meter

Description

Product overview
EM20-ER energy monitor use 2.8-inch TFT color LCD, it can monitor the household appliances’ power, power factor, voltage, current, frequency, total electricity consumption, elapsing of time and electricity fees, electricity consumption at one time, elapsing of time and electricity fees at one time. It records electricity consumption and fees every day, you can see the historical data in the form of charts or lists. EM20 energy monitor is suitable for detecting and recording the operation and energy consumption of household, factory, office and other electrical equipment, it can turn on or off the power supply (external relay version only) at a set time
Main characteristics：
 Digital operate and control;  2.8-inch TFT color LCD display;  0.5FS measuring accuracy;  Chinese and English can be set freely;  23 money units can be set;  6 touch buttons for setting;  The date can be set and the time can be set with 5 forms; 
It can be set automatically to be power on, power off, or keeping the working state after the last power off
;  Electricity includes total electricity and one-shot electricity, one-shot electricity can be cleared, in order to measure the electricity and cost in some situation;  In working condition, there are 4 main pages for choosing: General view, Total Electricity, One-shot Electricity, Realtime Electrical Parameter. The default is General view, user can press”” or”” to switch the different pages;  It records automatically the history data of electricity: elapsing of time, electricity consumption and electricity fees by list or chart, it can store the data for more than 30 years;  Electricity tariff support 4 decimals, the decimal point can be set to 0 between 4. It supports 3 charges: simple tariff, time-sharing tariff and stage tariff. Time-sharing tariff support 8 time periods to calculate the cost, which can be used for peak and valley billing. Stage tariff support 8 stages power rates. You can set the date that begin to charge the stage billing 
It has 9 timers, in which 2 are advanced. They can be set the specific time, date, working day or weekend to open or close the switch. The other 7 timers can be set to open or close the power at the specific time in a day.
 It has the function of alarm, you can set values for voltage, current, or power. If they were exceeded, the monitor will alarm automatically; 
It can protect itself by cutting off the power supply when the voltage, current, or power exceed the set value; it has automated recovery function. After this function was selected, when the monitor is in the output protection mode. 1 minutes later, it will open the power automated, if the value exceeds the set, it will cut off the power again to protect itself.
 Energy-saving setting: you can set that the screen will be closed without any action in 1minute, 5 minutes, or 10 minutes, or the screen can be set not to be closed. Even if the screen was closed, which not influence the monitor’s measuring. If any button is touched, the screen will be opened again;  It has the function of clearing the total electricity, history data and factory reset;  The power resolution can be switched automatically. When the power <1000W, it has one decimal, the unit is W; When the power <10kW, it has 3 decimals; the unit is KW; When the power >10kW, it has 2 decimals, the unit is KW;  If the measured is overrange, it will show “High” on the screen;  It supports 1000:1 or 2000:1 current transformer, the max current of the transformer is 120A; 
Only support single coil magnetic latching relay
;  Mounting box type 86 is used. Note 1: Red words are the specific function of this item .
