Destined for direct (up to 63A) and indirect measurements in 3 phase 4 wire/3 wire balanced and unbalanced systems. For direct (up to 63A) and indirect measurement (x/1A or x/5A). Indications considering values of programmed ratios.
- High accuracy class (0.2Sfor active energy)
- Measurement and recording of 54 power network parameters in 1-phase 2-wire or 3-phase 3 or 4-wire balanced and unbalanced systems
- Harmonics up to 63rd for current and voltage
- Backlight LCD screen, fully configurable by a user: 22 pages, 3 parameters in each; 1 page with harmonics presentation
- Memory of minimum and maximum values
- 2 configurable alarm outputs
- Mode of supervisory relay for alarm outputs - additional function
- 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: with additional module of analog outputs - S4AO type (4 current or voltage outputs)
- RS-485 digital output - MODBUS protocol
- Logging of up to 32 measured parameters in the internal memory 8 GB
- Modern and user-friendly Ethernet interface 10/100 BASE-T:
- protocol: MODBUS TCP/IP, HTTP, FTP
- services: www server, ftp server, DHCP client
- protocol: MQTT is ideal for communication in distributed acquisition systems data - IoT applications, see link → NR30IoT
- version with BACnet for BMS, see link → NR30BAC
