Main Functions and features:
On the EM737’S front panel, there are three LED, active/reactive energy pulse light, and alarm indicator lights.Meter can measure import & export active energy , import & export reactive energy. The measurement type can be set.
Smart meter have two status: cycle display status and button press display . When pressing the button, User can set according their request. Button press will Backlight the LCD. Display cycle can be set within 5~20 seconds, The default is 5 seconds.
Electricity parameters measurement and monitoring
Measure record and display voltage, current, power and power factors. error is not more than ±1%.
Provide out of limit monitoring capability, Voltage, Current, Power factor can be setup the limit value and monitoring.
With an infrared COM and a RS485 COM. Its physical layers are independent with each other. One communication channel will not be affected by the other one. The meter can realize data acquisition, broadcast time setting, read, program and manage through hand-held terminals, data acquisition terminal, test equipments and computers. Communication protocols fit Modbus RTU standard.
When the meter connect wire wrong example: current reverse, lost phase and reversed phase sequence , the meter will display , the ALARM led will be on.
Pulse output function
Smart meter is equipped with a pulse output which is fully separated from the inside circuit. That generates pulses in proportion to the measured energy .include the testing pulse output of active energy and reactive energy. 8/ 11 Test pulse output contact (P+/P-), 9/ 11 Test pulse output contact (Q+/Q-)
The meter can be programmed by pressing button on the panel such as Modbus ID, password,Baudrate etc..
Load Profile,3 channels 4095 recorders, interval 1-65535 min can be set
DO output (control by RS485 communication)
