Lumel-NR30
Rail mounted 3-phase power network meter with Ethernet and recording

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 63rd for current and voltage Baclit LCD screen, fully configurable by a 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 deley 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 protocol: MQTT - additional function To make protocol active, please order appropriate licence key – details in ordering code. Protocol can be also activated on the devices which have been alredy installed on the facility after softwate upgrade. 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. Modern design allows for installation of the meter in modular switchgear in accordance with EN 62208 (meter has a width of 6 modules) on 35 mm rail, External dimensions: 105 x 110 x 60mm.
