The GW Instek GPM-8320/GPM-8330 Power Meters are digital power meters specially designed for measuring power in three-phase AC sources (GPM-8320 has 2 modules, GPM-8330 has 3 modules). The power meters have a test bandwidth of DC, 0.1 Hz~100 kHz and have 16-bit A/D converters and a sampling rate of 300 kHz. The power meters have a 5 inch TFT LCD display that shows the measurement results in both numerical and graphical form, 5-digit readings, 25 different power measurement parameters and high-precision measurement functions are also provided. Furthermore, the GPM-8320 / GPM-8330 provide waveform display functions (voltage/current/power), integration measurement function, multi-order harmonics measurement and analysis (the measurement at 50/60 Hz meets the requirements of IEC61000 -4-7), external sensor inputs and a variety of communication interfaces.
The GPM-8320/8330 provides multiple wiring modes for input voltage configuration (1P3W/3P3W/3P4W/3V3A). Choose the wiring mode according to your specific needs to measure parameters for specific wiring methods and even calculate efficiency. The power meters have a nominal input voltage of 1,000 V, an input current of 20 A, a minimum current range of 0.5 A (resolution of 0.1 mA), a power measurement resolution of 0.1 mW, a crest factor of 3 ( at half range the CF can reach up to 6 or 6A) and a voltage/current/power measurement accuracy of ±0.1% reading ±0.05%. The power meters have different measurement modes (AC+DC/ AC/ DC/ V-MEAN) to get up to 25 parameters for power measurement.
