Electricity consumption meters LE-03MP

LE-03MP, 5908312597216
With network parameters analysis. Remote reading. Three phase. RS-485 port + Modbus RTU.
LE-03MP is a static (electronic) calibrated electricity meter of three-phase alternating current in a direct system. It is used for reading and recording of consumed  electric energy and mains parameters with remote readout via a wired RS-485 network.

  


    

Measured values
Active power - AE + [kWh]    
Reactive power - RE+ [kvarh]   
Phase voltage - U1, U2, U3 [V]    
Phase currents - I1, I2, I3 [A]   
Power factor cosϕ L1, L2, L3   
(20 parameters)
Active powers of L1, L2, L3 phases - P1, P2, P3 [kW]
Active power of L1+L2+L3 system - P [kW]
Reactive powers of L1, L2, L3 phases -  Q1, Q2, Q3 [kvar]
Reactive power of L1+L2+L3 system -  Q [kvar]
Frequency - F [Hz]
   

Features
* Internal relay switching L1, L2, L3 phase circuits.
* Remote control of ON/OFF relay.
* Overcurrent protection - setting the load threshold.
* Prepaid power (prepayment) - active power value at which the meter disconnects the internal relay.
* Automatic mode - activation of overcurrent protection and prepaid mode.
* Status - current status of the relay [on/off].
    

Operation
Under the influence of flowing current and applied voltage, the LE meter accurately measures the amount of consumed electricity. Energy consumption is indicated by flashing LEDs: “800 pulses/kWh” for active power and “800 pulses/kvar” for reactive power. In addition, the device  measures the mains parameters. The values ​​are displayed cyclically on LCD display. Parameter changes every 3 seconds. You can manually switch between successive parameters by pressing a key on the front-end of the meter. The display is active only with meter power supply on.
The meter has an internal relay that switches L1, L2 and L3 circuits. The (ON/OFF) relay can be also operated manually.

The meter has a program overcurrent protection. If the load threshold is exceeded, the internal relay opens for 5 minutes. After that time the relay closes and the measurement is repeated.

Prepaid power (prepayment feature) is the set increment value of available active power beyond which the internal relay is disconnected by the meter. Automatic operation is the mode with two active functions: automatic relay disconnection if the set overcurrent threshold is exceeded and switching on the prepaid mode.
Current state of relay (ON/OFF) is indicated on the LCD display as the corresponding modbus register value.
Readout of all measured values ​​and parameter setting functions is done via the Modbus RTU protocol.

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.
 


         

 LE-03MP Console
The LE-03MP Console application allows you to remotely read indications and set the prepaid values in LE-03MP (three-phase, direct measurement of 3×60 A) meters. The maximum number of supported meters in the network: 247.
The "prepaid" feature allows you to set the value of power intake to use, beyond which the meter cuts off the internal relay and prevents any further intake.
