Power quality meters with recording and MQTT (IIot), BACnet/IP or Modbus TCP/IP protocols

Product 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.
