Hioki 3390 - DC, 0.5 Hz to 150 kHz, 3-phase 4-wire, High Precision Power Analyzer
Suitable for use with 3 phase and capable of using 4-wire testing, the Hioki 3390 combines together a wide variety of features with high accuracy to help users gain full diagnostics of electrical equipment in order to improve overall power quality.
With the four wire method, both the primary and secondary sides of inverts can be measured at the same time. Alternatively multiple 3390 units can be configured and synchronised together for multiple channel measurements using dedicated software (sold separately).
This analyser is full of different functions; it can measure voltage, current, voltage/current waveform peak, active power, reactive power, power factor, phase angle, frequency, current integration, efficiency, loss, noise, harmonics and much more!
