NR30 DIN Rail mounted 3-phase power network meter

Designed 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 presentation
  • 2 Configurable alarm outputs
    • Mode of supervisory relay for alarm outputs – additional function
    • To make function active, please order appropriate license key – details in ordering code. Function can be also activated on the devices which have been already installed on the facility after software 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 occurred
  • Optional: with additional module of analogue outputs – S4AO type (4 current or voltage outputs)
  • RS485 digital output – MODBUS protocol
  • Logging of up to 32 measured parameters in the internal memory 8 GB
