The Carlo Gavazzi CPTDINAV51LA3AX is a compact and advanced DIN rail mounted energy transducer designed for accurate monitoring of key electrical variables in industrial power distribution, machinery and automation systems. As part of the Carlo Gavazzi CPTDIN Advanced series, it provides reliable measurement and analogue signal output for integration with PLCs, controllers, monitoring systems and building management platforms.
This transducer is designed to measure important electrical parameters including voltage, current, frequency, active power, apparent power, reactive power, power factor and energy values. Its three analogue outputs allow measured values to be transmitted as standard current signals, making it suitable for continuous monitoring and control applications where dependable electrical data is required.
With support for 230-347 V L-N, 400-600 V L-L systems and 5(6) A current transformer inputs, the CPTDINAV51LA3AX is well suited to three-phase energy monitoring applications. Its 18-60 V AC/DC auxiliary supply and compact DIN rail format make it easy to install inside electrical control panels and distribution boards.
Energy transducers such as the Carlo Gavazzi CPTDINAV51LA3AX convert measured electrical values into analogue output signals that can be used by PLCs, data loggers, remote I/O systems and automation controllers. This allows operators and engineers to monitor power consumption, electrical load and system performance from a central control platform.
The CPTDIN Advanced series is particularly useful in applications where compact installation, clear electrical measurement and reliable analogue output are required. Its DIN rail housing allows simple integration into new or existing electrical panels without requiring excessive cabinet space.
