GW INSTEK (Texio Technology) Digital power meter

The GPM-8320/8330 is a digital power meter compatible with multiple wiring configurations (1P3W/3P3W/3P4W/3V3A). *The GPM-8320 has two modes. It supports single-phase 2-wire to three-phase 4-wire systems, with a rated input voltage range of up to 1000V and an input current range of 20A. The minimum current input range is 0.5A (maximum resolution of 0.1mA), and the power measurement resolution is 0.1mW. For power measurement, it supports 25 diverse measurement items, including active power, apparent power, reactive power, and power factor. Furthermore, integrated measurement allows for the integrated power/current (Wh/Ah) measurement of the DUT for 8 measurement items. Multiple display modes: For numerical display during power measurement, there are standard and simple modes, and the displayed items can be arbitrarily changed from 25 measurement parameter options. The harmonic measurement mode offers two display options: a bar graph display for each order and a list display showing eight harmonic parameters. The integrated measurement range selection function includes an auto-ranging function effective during integrated measurements. Selecting only the desired range reduces the number of range changes, thus speeding up the process. The digital I/O (DA12) on the rear panel allows control of the unit and generation of D/A output. It is also possible to operate specific functions using HL signals. For harmonic measurement up to the 50th order, there are two display options: a visually easy-to-understand bar graph display and a list display showing eight parameters. Saving to a log file is also possible, which is useful for evaluating power supply units of home appliances and electrical equipment. The remote interface comes standard with various interfaces for remote communication. This allows for flexible creation of programs for control using remote commands and for acquiring measurement results.
