NR30 DIN Rail mounted 3-phase power network meter

Destined for direct (up to 63A) and indirect measurements in 3 phase 4 wire/3 wire balanced and unbalanced systems.

► Measurement and recording of 54 power network parameters in 1-phase 2-wire or 3-phase or 4 wire balanced and unbalanced systems.
► Harmonics up to 51st for current and voltage

► Backlit LCD screen, fully configurable by a user
●22 pages, 3 parameters in each
● 1 page with harmonics presentation

► Indications include the values of programmed ratios
► Memory of minimum and maximum values

► 2 configurable alarm outputs
● Mode of supervisory relay for alarm outputs - additional function. To make function active, please order appropriate license key - details in ordering code. Function can be also activated on the devices which have been already installed on the facility after software upgrade.
● 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 analogue outputs - S4AO type (4 current or voltage outputs)
► RS485 digital output - Modbus protocol
► Logging of up to 32 measured parameters in the internal memory 8GB

► 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 - additional function: To make protocol active, please order appropriate license key - details in ordering code. Protocol can be also activated on the devices which have been already installed on the facility after software upgrade
