NR30IoT, 3-Phase Mains Network Meter for DIN Rail Mounting

NR30IoT, 3-Phase Mains Network Meter for DIN Rail Mounting

The NR30 Meter from LUMEL is suitable for direct (up to 63A) and indirect measurements of 54 network parameters and current and voltage harmonics upt to the 63rd in symmetrically or asimmetrically loaded single-phase 2-wire systems and three-phase 3- or 4-wire systems.

With the MQTT protocol, it is ideally suited for communication in distributed acquisition systems data and IoT applications.

Characteristics:

• High accuracy class (0.2s for active energy)
• Backlit LCD screen fully configurable by the user (22 views, 3 parameters in each)
• For direct (up to 63A) and indirect measurements (x/1A or x/5A)
• Indications considering values of programmed ratios
• Memory of minimum and maximum values
• 2 configurable alarm outputs
• Digital output RS-485 - MODBUS protocol
• Archiving of up to 32 measured parameters in the internal 8 GB memory
• Modern and user-friendly Ethernet interface 10/100 BASE-T

• Programming of parameters through USB using free eCon software
• Battery backup RTC.
• Modular housing for DIN rail according to EN 62208 (the meter has a width of 6 modules)
