GW Instek GPM-8213 AC power meter

GW Instek’s GPM-8213 power meter is designed specifically for single-phase AC power supply measurements. Powerful features — including five-digit measurement display, integral measurement function, front/rear panel input terminals and various communications ports — enable clear, convenient measurements.

The product provides as many as 19 power measurement parameters, including voltage, current, frequency, power, crest factor, apparent power, reactive power, power factor, phase angle and total harmonic distortion, as well as voltage/current/power measurement capabilities (reading: ±0.1%; level: ±0.1%).

The device includes a 4″ TFT LCD, which works in simple mode and standard mode. Simple mode displays the conventional power meter’s four measurement parameters, to meet clarity requirements for tests during the manufacturing process. Standard mode extends the display to the maximum of eight measurement parameters (two major measurements and six monitor measurements) to satisfy the various measurement application requirements of R&D, design and quality verification.

For DUTs requiring an IEC 62301/EN 50564 standby power consumption test, the device provides the optimum measurement support, including test frequency bandwidth of DC ~6 kHz, the minimum current level of 5 mA (resolution: 0.1 µA), power measurement resolutions (1 µW for minimum current and voltage levels; 1 mW for maximum current and voltage levels), a crest factor reaching 3 (half-range reaching 6) and measurement of total harmonic distortion. For large-voltage/large-current measurement applications of general power measurement, the product provides PT/CT rate function to collocate with external potential transformer or current transformer to meet the measurement requirements.

The RS232C/USB interfaces (virtual COM)/LAN can be used to edit and retrieve programs or the optional GPIB interface (installed by manufacturer) can be selected to meet users’ automatic test system requirements.
