The Carlo Gavazzi CPTDINAV51LA1AX 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 provides a 20 mA DC analogue output for connection to PLCs, controllers and monitoring systems.
This transducer is ideal for industrial control panels, distribution boards and energy management applications where reliable electrical measurement 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 operation and a 18 to 60 V AC/DC auxiliary supply, the CPTDINAV51LA1AX provides a practical analogue output solution for industrial power monitoring applications.
Energy transducers such as the Carlo Gavazzi CPTDINAV51LA1AX convert measured electrical parameters into a standard analogue signal that can be used by automation and energy monitoring systems. This allows engineers to monitor load, demand, energy usage and operating conditions through PLCs, controllers or data acquisition equipment.
The CPTDINAV51LA1AX 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 20 mA DC analogue output make it suitable for industrial systems requiring compact and dependable power monitoring.
