Power network meter with Ethernet and recording dedicated to IoT applications
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
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).
Measured value : current, voltage, temperature, power
Display : LCD
Other characteristics : analog output
