Why Choose the Carlo Gavazzi CPTDINAV51HS1BX Power Transducer?

The Carlo Gavazzi CPTDINAV51HS1BX is a compact DIN rail power transducer designed for monitoring electrical variables in low voltage AC systems. As part of the Carlo Gavazzi CPTDIN Basic range, it provides measurement of key power parameters and communicates data through an integrated RS485 serial port.

This transducer is suitable for industrial control panels, distribution boards and energy management systems where remote monitoring is required without a local display. It is designed for 5(6) A current transformer inputs and can be used in compatible single-phase and three-phase balanced load applications.

With a rated measurement range of 400/690 V L-L, 90–260 V AC/DC auxiliary supply and DIN rail mounting, the CPTDINAV51HS1BX is a practical solution for transmitting voltage, current, power, energy and related electrical values to PLCs, SCADA platforms and monitoring systems.
