N20Z - Tri Colour Digital Meter for AC Parameters

N20Z - Tri Colour Digital Meter for AC Parameters


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

The device fulfils the requirements of installation's category III for the product designed.


Parameters of the N20Z meter: 

  • Input:
    • AC current: 1 A, 5 A,
    • AC voltage: 100 V, 250 V, 400 V 
    • frequency: 20...500 Hz.
  • 2 alarm outputs of OC type (4 types of alarms) signalled by highlight of the alarm index,
  • 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 AC / DC or 20...40 V AC / DC
  • Overall dimensions: 96 x 48 x 64 mm.

For the configuration of the N20Z is destined LPConfig & econ program. The meter must be connected with the PC computer through a PD14 converter. 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 AC or AC + DC (True RMS),
  • Averaging time of the measurement,
  • Recounting of indications (individual characteristic),
  • Two alarms of OC type operating in six working modes.
