Carlo Gavazzi Controls S.p.A. CPA Family CPA300V DS ENG 22/07/2020 Contactless power analyzers

Description

CPA is a family of power analyzers and current transducers for ac 1-phase or dc installation monitoring, thanks to Hall effect sensing. Current is measured with no contact with the copper wire. The comprehensive set of measured variables allow this device to be used to monitor photovoltaic installations, industrial processes, battery charging systems. Benefits

• Flexible solution. The instrument allows users to monitor both ac and dc system with the same device.
• Fast connection. ac or dc current sensing with no need to cut and join the cable.
• Reliability. The instrument is equipped with a Modbus/ RTU communication port by RS485 connection.
• Complete monitoring. Depending on the model, the instrument provides a comprehensive range of monitored variables (V, A,W, var, VA, kWh, PF, HZ, THD) or limited to current variables (A, Amin, Amax, Ah).
• Wide range of device mounting types. The instrument can be mounted in four different ways (either DIN rail or panel mounting, vertical or horizontal) to match different installation constraints.
• Easy programming. Plug’n play set-up by means of CARLO GAVAZZI UCS (Universal Configuration Software).
• Integrated solution. The instrument is compatible with both UWP 3.0 and VMU-C EM solutions for energy monitoring.

Applications

CPA power analyzers are the ideal solution for those applications which are beyond standard ac monitoring. Given their capability of working both at different frequency ranges, they match the needs of dc applications (battery charging, photovoltaic monitoring), of ac applications with high crest factor (UPS, variable frequency drives) and standard 1-phase ac installations. Main functions

• Compatible with VMU-C EM and UWP 3.0
• Configurable by means of UCS (Universal Configuration Software) solution
• Hall effect sensing

Carlo Gavazzi Controls S.p.A. CPA Family CPA300V DS ENG 22/07/2020 CPA system architecture for ac system CPA operating principles for ac systems CPA is a power analyzer, measuring current with contactless Hall effect sensing and voltage with shunt based technology. Power, power factor, energy, frequency and harmonic distortion (up to the 40th harmonic) are also measured by CPA with true RMS up to 400 Hz. The measured variables are available to the monitoring system connected through RS485, via Modbus/RTU communication. UCS (universal configuration software) installed onto a PC connected to CPA via RS485, allows to configure CPA (i.e. RS485 parameters) with ease and display measured variables in real time; configuration parameters are saved in both CPA's memory and UCS' database. UCS allows to create, edit and exchange configurations of both single CPA meters and complete networks of CPA units.
