Description

PRODUCT DESCRIPTION

1-Phase Power Network Digital Panel Meter, N30P

N30P meter is destined to measure: a.c. voltage, a.c. current, active, reactive and apparent power, cos φ, tg φ, φ, frequency, active, reactive and apparent energy, 15 min. active power, 10 min. voltage, 10 sec. frequency in single-phase power network.

Features:

  • Input:
    • current: 0…1 or 0…5A
    • voltage: 0…100V or 0…400V
  • Output: relay (4), analog (1), energy pulse (1), digital RS485/MODBUS (1)
  • 3-colour display – red, green and orange programmable in three intervals of the measured value
    • 14mm digit hight
    • highlighted measuring units
  • 4 alarm outputs with signalling by LED diodes, operating in 6 different modes,
  • Conversion of any measured value into a 0/4…20mA or 0…10V analog signal,
  • Storage of minimal and maximal values for all measured quantities,
  • Meter programming from the keyboard or through the RS485 interface by means of free delivered LPConfig 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,
    • averaging time of the measurement,
    • recounting of indications (individual characteristic).
  • Supply: 85…253 V AC/DC or 20…40 V AC/DC
  • Protection level from frontal side: IP65,
  • External simension: 96 x 48 x 64mm.
