Overview

The WT1800E High performance power analyzer can measure both the small currents of products called energy saving designed as well as the large currents involved in large-sized loads. As it handles voltages ranging from 1.5 V to 1000 V, it has a wide variety of uses. Since 3 phase power can be input from two separate systems (6 inputs), you only need one WT1800E to simultaneously measure Input/Output signals from inverters with normal/harmonics data as fast as 50 ms.
