Intuitive and advanced compact energy analyzers

Carlo Gavazzi has introduced model EM530 and EM540 three phase energy analyzers. The EM530 is a Class 0.5S (kWh) analyzer which measures currents up to 10,000 A via 5 A current transformers, and the EM540 is a Class 1 (kWh) analyzer which measures current up to 65 A via direct connection, the company says, eliminating the need for current transformers.

The Carlo Gavazzi 3-phase power analyzers can be used for two and three phase systems, as well as wild-leg systems.

Units can measure most relevant instantaneous electrical variables, energy consumption, and harmonic distortion, it adds.

Both models feature high speed 100 ms serial data refresh rates, making them suitable for load balancing energy storage or EV charging applications.

Fast commissioning is said to be possible thanks to an intuitive wizard setup menu, along with instant notification of wiring errors and suggestions for correcting them.
