Carlo Gavazzi CPTDINAV51HS2AX DIN rail energy transducer for three-phase electrical monitoring, with 230 to 347 V L-N, 400 to 600 V L-L, 5(6) A CT input and RS232 Modbus RTU communication.
£353.47
The Carlo Gavazzi CPTDINAV51HS2AX is a compact and advanced DIN rail energy transducer designed for accurate monitoring of three-phase electrical systems. As part of the Carlo Gavazzi CPTDIN Advanced range, it measures key electrical parameters and communicates the data via an integrated RS232 Modbus RTU interface.
This transducer is ideal for industrial control panels, distribution boards and energy management systems where reliable remote monitoring is required without a local display. It supports standard 5 A current transformer inputs and is suitable for low voltage installations requiring continuous measurement of power, energy and operating conditions.
With voltage measurement ranges from 230 to 347 V L-N and 400 to 600 V L-L, support for 50/60 Hz systems and a wide 90 to 260 V AC/DC auxiliary supply, the CPTDINAV51HS2AX provides a practical solution for connecting energy data to PLCs, SCADA platforms and monitoring systems.
Energy transducers such as the Carlo Gavazzi CPTDINAV51HS2AX convert measured electrical parameters into communication data that can be used by automation and energy monitoring systems. This allows engineers to monitor load, demand, energy usage and operating conditions from a remote platform.
The CPTDINAV51HS2AX is designed for DIN rail installation and can be integrated into low voltage electrical panels for machine monitoring, distribution board measurement and energy management. Its CT-based current input and RS232 Modbus RTU communication make it suitable for industrial systems requiring compact digital power monitoring.
