Lumel-ND30
Power network meter with Ethernet, recording and graphical screen

Measurement of 54 parameters, harmonics up to 63rd, 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 ND30 type. 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 pages, 8 parameters in each 2 pages with harmonic presentations 1 page 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 - function available from 02.2019. Function can be ordered with new device as well as activated on the devices which have been alredy installed on the facility after softwate upgrade (from 1.07 version). To make function active, please order appropriate licence key (here)  - LKEY type. 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: 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 (option). Digital output RS-485 - MODBUS protocol. Modern and user-friendly Ethernet interface 10/100 BASE-T (option): protocol: MODBUS TCP/iP, HTTP, FTP, MQTT protocol - available from 02.2019. Protocol can be ordered with new device as well as activated on the devices which have been alredy installed on the facility after softwate upgrade (from 1.07 version). To make function active, please order appropriate licence key (here)  - LKEY type  services: www server, ftp server, DHCP client. 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.
