The LUMEL NA5-TRU00410008 is a programmable digital power transducer designed for single-phase or three-phase networks. It measures key electrical parameters (V, A, Hz, kW, kWh) and provides both an analog output and RS-485 MODBUS communication. Housed in a compact 96x48mm DIN enclosure, it is ideal for industrial switchgear, marine switchboards, and energy management systems requiring precise monitoring and remote data acquisition.
DIGITAL PANEL METER WITH BARGRAPH – LUMEL NA5
The LUMEL NA5-TRU00410008 is a versatile multifunction transducer from the advanced NA5 series, engineered to deliver comprehensive electrical metering and seamless system integration in industrial and marine environments. This model is specifically configured for universal supply and network communication.
Comprehensive Power Monitoring
This unit is capable of accurately measuring the key parameters of an electrical installation, including:
-
Phase and Line Voltages (V)
-
Phase Currents (A)
-
Frequency (Hz)
-
Active, Reactive, and Apparent Power (kW/kvar/kVA)
-
Active and Reactive Energy (kWh/kvarh)
-
Power Factor (cosφ)
Flexible Integration and Outputs
The NA5-TRU00410008 stands out due to its multi-function outputs. It features:
-
1 Configurable Analog Output: The analog output (e.g., 4-20mA or 0-10V) can be programmed to retransmit any of the measured values (like power or current) to external PLCs, recorders, or remote displays .
-
RS-485 Communication Port: Equipped with a galvanically isolated RS-485 interface running the MODBUS RTU protocol, this device can be easily integrated into larger SCADA, BMS, or ship automation systems. This allows for centralized monitoring of energy consumption and power quality from a control room .
-
Pulse Output (Energy): The unit can also function as an energy meter, providing a pulse output proportional to the consumed energy (kWh) for feeding into totalizers or for billing purposes .
Rugged Design for Industrial Use
Housed in a durable 96x48mm (DIN 43700) case, it is designed for flush mounting on switchboard panels. It operates reliably in a wide temperature range and features a high ingress protection (IP 54 from the front), making it suitable for the harsh conditions found in industrial plants and marine engine rooms. The supply voltage for this specific model is 85-253V AC/DC, making it universally adaptable to various control panels without needing an external power supply module.
