High Accuracy Power Analysis in a Portable Device

Hioki has enhanced the legacy 3390 Power Analyzer with the new PW3390 Series Power Analyzer, a 4-channel device with a built-in motor analysis option, to deliver a high accuracy power analysis regardless of the measurement situation.   The PW3390 series offers a power accuracy of ±0.04% rdg. and a DC to 200kHz measurement bandwidth, which covers the range necessary to correctly measure the input and output power of inverter devices as well as the efficiency level of high-efficiency equipment.  In addition, a built-in current sensor phase shift function based on a new virtual oversampling technology enables the phase characteristic compensation of current sensors at 0.01° resolution, resulting in the accurate measurement of even high frequency power with low power factors. 17 Hioki current sensors rated 20 A to 6000 A are available to pair with the PW3390 to meet applications ranging from automotive power to infrastructure equipment testing, resulting in a flexible lineup of power analysis devices to accommodate any measurement situation.
