The WT1600 is power meter designed for measurement of extremely small currents in energy-saving equipment, as well as measurement of large currents for evaluating large-sized loads. The WT1600 works with voltages ranging from 1.5 V up to 1000 V, supporting a wide range of applications. Because it can accept signal inputs for up to six phases, a signal WT1600 unit can measure I/O signals on inverters. A single WT1600 unit can make up to six different power measurements (six input each for voltage and current). With the measure start-stop function (synchronized measurement), two WT1600 units (12 inputs) can be synchronized. * Up to Six-Phase Input on One Unit. Synchronized Measurements Between Two Units * Wide Current Input Ranges * Data Storing as Fast as 50 ms (20 Times per Second) * High Precision and Wide Bandwidth * Increased Assured-Accuracy Range for High-Precision Measurements * A Variety of Display Formats * Display Harmonic Data as Bar Graphs, Vectors, and Lists * Built-in Printer (Optional) * A Variety of Interfaces (Optional) * Integration Function Capable of Handling Rapid Changes in Input Signal * Other Special Features Wide Current Input Ranges The WT1600 has two different input elements. A 5 A input element is provided for measuring extremely small currents, while a 50 A input element serves to measure large currents. Both of the elements can be installed together in the WT1600. The current for the 5 A input element can be set as low as 10 mA for measuring extremely small currents in energy-saving equipment. * Two input elements * 5 A input element * 10/20/50/100/200/500 mA, 1/2/5 A (DC, 0.5 Hz to 1 MHz) * 50 A input element * 1/2/5/10/20/50 A (DC, 0.5 Hz to 100kHz) Current sensor input range (same for 5 A and 50 A input elements; standard) 50/100/250/500 mV, 1/2/5/10 V (DC, 0.5 Hz to 500 kHz)
