Description

Sifam Tinsleys ND31 power quality meters with recording and MQTT (IIoT), BACnet/IP or Modbus TCP/IP protocols.

Measurement of 54 parameters, harmonics up to 63rd, MQTT protocol dedicated to IIoT applications, graphical screen-fully configurable by a user and very user- friendly www server interface - these are just some advantages of our new power network meter ND31 type.

Features

Features

  • Measurement and recording of 54 power network parameters, including current  and voltage harmonics up to 63rd, in 1-phase 2-wire or 3-phase 3- or 4-wire balanced and unbalanced systems.
  • Color graphical display: LCD TFT  3,5’’, 320 x 240 pixels, fully configurable by user:
    • 10 screens, 8 parameters in each,
    • 2 screens with harmonic presentations,
    • 1 screen with analog indication.
  • Indications include the values of programmed ratios.
  • Memory of minimum and maximum values.
  • 2 configurable alarm outputs.
    • Mode of supervisory relay for alarm outputs.
      Supervisory relay mode enables detection of following events:
      • voltage drop or growth
      • current drop or growth
      • phase loss
      • current or voltage unbalance
      • phase sequence
    • User can specify:
      • the thresholds of monitored events
      • monitoring of phase relay
      • memory of relay state
      • delay of switch-on/off relay
      • relay state after the event has occured.
  • Optional: analog output 0/4...20 mA and 2 x Pt100 inputs (e.g for measurement of transformer temperature).
  • Logging of up to 32 measured parameters in the internal memory 8 GB.
  • Digital output RS-485 - MODBUS protocol.
  • Modern and user-friendly Ethernet interface 10/100 BASE-T:
    • protocol: MODBUS TCP/iP, HTTP, FTP,
    • MQTT protocol,
    • BACnet/IP protocol,
    • services: www server, ftp server, DHCP client, NTP server.
  • Wide range of voltage supply:
    • 85..253 V a.c. or 90..300 V d.c.
    • 20..40 V a.c or 20..60 V d.c.
  • Programming of parameters using free eCon software.
  • Battery backup RTC.
  • Overall dimensions: 96 x 96 x 77 mm.
