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 ND31 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 screens, 8 parameters in each,
- 2 screens with harmonic presentations,
- 1 screen 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.
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 occured.
- Mode of supervisory relay for alarm outputs.
- 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.
- Digital output RS-485 - MODBUS protocol.
- Modern and user-friendly Ethernet interface 10/100 BASE-T:
- protocol: MODBUS TCP/iP, HTTP, FTP,
- MQTT protocol,
- BACnet/IP protocol,
- services: www server, ftp server, DHCP client, NTP server.
- 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.
- Overall dimensions: 96 x 96 x 77 mm.
