Energy meter LE-03M

Energy meter LE-03M

LE-03M

Remote reading. Three phase. RS-485 port + Modbus RTU.
LE-03M is a static (electronic) rated energy, which is to serve as an auxiliary meters to measure energy consumption in a three phase direct system. It is used for readings and recordings taken power with remote readout via a RS-485 protocol.



 
 

Functioning
The meter LE-03M with the influence of the flowing current and the applied voltage shall accurately measure the amount of energy consumed by each phase. Energy consumption is sygnaled by flashing of LEDs (800 pulses/ kWh), The sum of energy absorbed by the three phases is converted into the total energy taken by the three-phase system,and its value is displaied by the LCD. Digits after the decimal point means hundredths of kWh (0.01 kWh = 10 Wh).
Communication with the rate of working as a slave device is in compliance with the standard Modbus RTU via RS-485. Record the readings give the result in terms of kWh according to the indications on the display indicator. Each of the indicators is identified by a unique address assigned by the user.
  


 


 

Note!
Indicator has a pulse output SO+ - SO-. This allows you to connect another pulse device reading (SO) pulses generated by the meter. For proper operation of the meter is not required to connect additional devices.
Indicator has a sealable terminal covers input and output do to prevent bypass the meter.

Programs for remote reading of electricity meters
LE-01M, LE-01MP, LE-01MQ, LE-03M, LE-03MP, LE-03M CT

 

MeternetPRO
The MeternetPRO application allows remote reading of states and indications of counters, multimeters, measuring transducers, expansion modules of input/output and other measuring devices communicating through Modbus RTU protocol. The exchange of data between devices and the application is executed through RS-485 or local area network (LAN). The application, along with the database is installed on a special MT-CPU-1 server, which operates in a local network. Software user interface is a web application (web site). Access to the application is executed through any web browser. In a LAN with a public IP address, you can configure the application and read the data over the Internet.
 


           

Subscription billing of electricity consumption module
Module of the subscription billing of the power consumption or other recorded incremental value, for example: water, heat, etc. It allows you to calculate the increases in the value in the designated billing periods (intervals). Cycles: monthly, weekly, daily, hourly. The module allows you to create multiple individual and parallel reports.
 

    


  

Meternet
Program allows remote reading via RS-485 network display up to 1000 indicators.
Exchange of data between the counters and the application is done via a standard RS485 <-> USB port or server on the LAN (Ethernet). For LAN connection to the router with a static IP address, you can read the data via the Internet.
