ENIP-2 Standard

ENIP-2 provides instant and averaged true RMS values of the signal and its fundamental harmonic. Averaging interval can be selected from a range of 200 to 2000 ms, while instant values are updated every 50 ms. The measurement range is up to 200% Irated and 150% Urated Optionally, an extended operation mode can be enabled for measuring current up to 800% Irated (40 A).

No external power is needed to configure the device and update the firmware when ENIP-2 is connected to a PC via USB interface.

ENIP-2 Standard is housed in a plastic enclosure for DIN rail mounting. 

One or two RS-485 ports. The second RS-485 port can be used for a redundant data transmission channel, or for connecting external devices. The RS-485-2 port is pinned out to two RJ45 sockets: the left one is used for connecting ENMV-1, and the other one for ENMI.


  • voltages RMS (phase, phase-to-phase and average);
  • currents RMS (phase  and average);
  • power (active, reactive and apparent: per phase and total);
  • frequency;
  • power factor (per phase and apparent);
  • active and reactive energy in direct and reverse directions.

ENIP-2 uses 50 ms sliding window measurement calculation method. The values are updated every 20 ms.

Power quality

  • voltage sequences;
  • voltage unbalance and distortion;
  • curent sequences;
  • current unbalance and distortion;
  • THD;

For monitoring purposes ENIP-2 has a set of confiurable thresholds.


Switchgear equipment control using integrated binary outputs or using external ENMV-1 telecontrol modules, which are connected to ENIP-2.

Data display

Using external ENMI display modules it is possible to visualize values of main measured and calculated parameters. It is possible to display data from single ENIP-2 on several ENMI modules or visualize data from several ENIP-2 on single ENMI module. Display modules may be structurally combined with ENIP-2.
