N20Z Plus

The N20Z PLUS meter is a digital programmable panel instrument destined for measurements of a.c. voltages, a.c. currents, or frequency. The readout display is a LED display which enables the exposition of results in red, green or orange colour.


  • Input:
    - a.c. current: 1 A, 5 A,
    - a.c. voltage: 100 V, 250 V, 400 V 
    - frequency: 20...500 Hz.
  • 2 alarm outputs of OC type (4 types of alarms) signaled by highlight of the alarm index,
  • Digital output RS485 with Modbus RTU protocol
  • Protection level ensured by the housing: IP65,
  • Readout field: 5 three-colour LED displays of 14 mm height,
  • Highlighted measuring units,  
  • Supply: 85...253 V a.c./d.c. or 20...40 V a.c./d.c.
  • Overall dimensions: 96 x 48 x 64 mm.

For the configuration of the N20ZPLUS is destined free eCon software. Parameters which can be reprogrammed are as follows:

  • Display colour, individually in three intervals,
  • Thresholds of displayed overflows,
  • Display precision of the result (decimal point),
  • Highlight of the unit,
  • Kind of the measured signal a.c. or a.c. + d.c. (True RMS),
  • Averaging time of the measurement,
  • Recounting of indications (individual characteristic),
  • Two alarms of OC type operating in six working modes.
