DIN Rail mounted 3-phase power network meter NR30

Destined for direct (up to 63A) and indirect measurements in 3 phase 4 wire/3 wire balanced and unbalanced systems.

• Measurement and recording of 54 power network parameters in 1-phase 2-wire or 3-phase 3 or 4-wire balanced and unbalanced systems.
• Harmonics up to 51st for current and voltage
• Baclit LCD screen, fully configurable by user
  • 22 pages, 3 parameters in each
  • 1 page with harmonics presentation
• Indications include the values of programmed ratios
• Memory of minimum and maximum values.
• 2 configurable alarm outputs.
  • Mode of supervisory relay for alarm outputs – additional function
  • To make function active, please order appropriate licence key – details in ordering code. Function can be also activated on the devices which have been alredy installed on the facility after softwate upgrade.
• 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: with additional module of analog outputs – S4AO type (4 current or voltage outputs)
• RS-485 digital output – MODBUS protocole
• Logging of up to 32 measured parameters in the internal memory 8 GB
• Modern and user-friendly Ethernet interface 10/100 BASE-T:
  • protocol: MODBUS TCP/IP, HTTP, FTP,
  • services: www server, ftp server, DHCP client
