EM530 and EM540 three phase energy analyzers are targeted to assist manufacturers and end users in monitoring and managing escalating energy costs. The EM530 is a Class 0.5S (kWh) analyzer, which measures currents up to 10,000A via 5A current transformers. The EM540is a Class 1 (kWh) analyzer that measures current up to 65A via direct connection, eliminating the need for current transformers. These power analyzers can be used for two and three phase systems, as well as wild-leg systems. They can measure instantaneous electrical variables, energy consumption and harmonic distortion. Both feature high-speed 100 ms serial data refresh rates.
