Carlo Gavazzi has launched of EM530 and EM540 three-phase energy analyzers.
The EM530 is a Class 0.5S (kWh) analyzer which measures currents up to 10,000A via 5A current transformers, and the EM540 is a Class 1 (kWh) analyzer which measures current up to 65A via direct connection, eliminating the need for current transformers. These 3-phase power analyzers can be used for two and three phase systems, as well as wild-leg systems. They can measure electrical variables, energy consumption, and harmonic distortion.
The features of the EM530 and EM540 include:
Voltage inputs up to 415 VL-L AC, self-powered
Current and voltage THD (up to 15th harmonic)
Energy measurements (imported/exported): total kWh, kvarh, kVAh; partial kWh, kvarh, kVAh. Total kWh by phase.
Run hour meters (both imported and exported energy: 8+2 DGT). Total operating time.
