Panel-mount power meter ND30IoT

three-phase

Measurement of 54 parameters, harmonics up to 63rd, MQTT protocol dedicated to IoT applications, 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 ND30IoT type. -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. -MQTT protocol - ideal for IoT applications -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 -delay of switch-on/off relay
