Why Choose the Carlo Gavazzi CPTDINAV51HA3AX Energy Transducer?
The Carlo Gavazzi CPTDINAV51HA3AX is a compact and advanced DIN rail energy transducer designed for three-phase electrical monitoring applications. As part of the Carlo Gavazzi CPTDIN advanced transducer range, it converts measured electrical values into 3 analogue 20 mA DC outputs for connection to PLCs, controllers and monitoring systems.
This transducer is ideal for industrial panels, machine control systems and energy management applications where accurate measurement is required without a local display. It supports 5 A current transformer inputs and is designed for low voltage distribution systems, making it suitable for integration into existing electrical monitoring and automation installations.
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 energy metering for both consumption and generation, the CPTDINAV51HA3AX provides a reliable solution for monitoring power, energy and key electrical parameters in three-phase networks.

Reliable Power Transducer for Three-Phase Monitoring
Energy transducers such as the Carlo Gavazzi CPTDINAV51HA3AX allow key electrical values to be measured and transmitted to automation equipment using standard analogue output signals. This makes them especially useful in panels where a PLC, controller or monitoring system requires continuous visibility of electrical load, generation or process-related power usage.
The CPTDINAV51HA3AX 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 three analogue outputs make it particularly useful where multiple measured variables need to be transmitted simultaneously to control or monitoring equipment.
Typical Applications
Industrial electrical control panels.
Three-phase machine power monitoring.
