Contactless Power Analyser, 50 A AC/800 V AC, 50 A DC/1000 V DC, RS485 Modbus RTU

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.

Main 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, VMU-C EM e UWP 4.0 solutions for energy monitoring.

Main functions

• Compatible with VMU-C EM, UWP 3.0 and UWP 4.0
• Configurable using UCS (Universal Configuration Software) solution
• Hall effect sensing

Applications

CPA power analyzers are the ideal solution for those applications that 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.
