Gw Instek GPM-8310/DA4 Digital AC Power Meter with opt DA4

The GW Instek GPM-8310 DA4 is a digital power meter for single-phase (1P/2W) AC power measurement. Features include DC, 0.1Hz~100kHz test bandwidth, 16bits A/D, and 300 kHz sampling rate. It adopts 5" TFT LCD screen with a five-digit measurement display and provides 25 power measurement related parameters, and has a high-precision measurement capability. The GPM8310DA4 also features the ability to display waveform (voltage/current/power), the integration measurement function, harmonic measurement and analysis of each order, external sensor input terminals, and various communication interfaces, etc., to help users achieve clear, convenient and accurate power measurements.

The rated direct input voltage of GPM-8310 DA4 is 600V and the input current is 20A. The minimum current level is 5mA (resolution up to 0.1uA) and the power measurement resolution is 0.1uW. The crest factor can reach 3 (half measurement range can reach 6 or 6A), and the voltage/current/power measurement capability can reach (±0.05% reading ±0.1% level). Different measurement modes can be selected according to ( AC+DC/ AC/ DC/ V-MEAN), providing up to 25 relevant parameters for power measurement, including voltage (Vrms/ Vac/ Vdc/ Vmn/ V+pk / V-pk), current (Irms/ Iac/ Idc/ I+pk/ I-pk), frequency (VHz/ IHz), power (P/ P+pk/ P-pk), crest factor (CFV/ CFI), apparent power (VA), reactive power (VAR), power factor (PF), phase angle (DEG), total harmonic distortion rate (THDV/THDI), maximum current ratio (MCR), and the MATH calculation function. Hence, for the measurement of low current/low power such as standby power consumption, or the measurement of power consumption of general products, this power meter provides the best range and accuracy support.

In terms of data retrieval and storage, GPM-8310 DA4 provides a variety of communication interfaces including RS-232C/ USB device (virtual COM)/ LAN/ GPIB. Users can write programs to read the measurement results according to their habits or with existing system interfaces and there is no need to procure interfaces. USB host supports GPM-8310 screen capture, internal record data access, and firmware update. For the needs of external signal control or the use of data recorder to record data, GPM8310DA4 also provides a Digital I/O (DA4) interface, which can be connected to an external controller such as PLC or a data recorder to meet the application of automatic measurement or long recording.
