ND30 Series Network Analyser
Central Measurement ND30
Measurement of 54 parameters, harmonics up to 51st, 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 51st, in 1-phase 2-wire or 3-phase 3 or 4-wire balanced and unbalanced systems.
► Colour graphically 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 analogue indications
► 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 already installed on the facility after software upgrade (from 1.08 versions). to make function active, please order appropriate license key.
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: analogue output 0/4...20mA and 2 x Pt100 inputs (e.g. for measurement of transformer temperature)
► Logging of up to 32 measured parameters in the internal memory 8GB (option)
► Digital output RS485 - 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 already installed on the facility after software upgrade (from 1.07 version). To make function active, please order the appropriate license key.
● Service: www server, ftp server, DHCP client
► Wide range of voltage supply
● 85 ... 253 Vac or 90 ... 300 Vdc
● 20 ... 40 Vac or 20 ... 60 Vdc
► Programming of parameters using free eCon software
► Battery backup RTC
► Overall dimensions: 96 x 96 x 77 mm
