LUMEL LED Digital 3-Phase Power Network Meter with RS-485 Interface, Ethernet and Internet N14

The N14 meter is a programmable digital panel instrument destined for the measurement of 3-phase, 3 or 4-wire power network parameters, in balanced or unbalanced systems.

• Measurement of power network parameters in 3 or 4-wire balanced or unbalanced systems.
• Tetraquadranti c measurement of power and energy (P+, P-, QL, QC).
• Indications taking into consideration values of programmed ratios.
• Measurement of 15-minutes’ mean power.
• Digital transmission to the Master system through the RS-485 interface  (MODBUS).
• Configurable alarm output and current and voltage ratios.
• Programmable parameters using pushbuttons or through the RS-485 interface using the free eCon program.
• Impulse output of OC type for the retransmission of 3-phase active  energy.
• Battery support of configuration data and state of watt -hour   
• meters at supply decays.
• Detection and signaling of incorrect phase sequence.

• Measured value:
  • RMS voltage and current, 
  • active, reactive and apparent power,
  • active, reactive and apparent energy,
  • power factors, 
  • frequency,
  • mean active power ( e.g. 15-min mean power).
• Kind of outputs: RS-485 with MODBUS protocol
  • alarm – relay
  • impulse – OC
• Communication in network:
• RS-485 interface,
• ETHERNET (through PD8),
• INTERNET (through SM61)
