3-Phase 4-Wire Power Quality Analyzer Compliant to IEC61000-4-30 Class A Standards with Dynamic 1300V Range, Harmonic and Inter-harmonics Analysis Capabilities Hioki portable power meters and analyzers are best in class power measuring instruments for measuring single to three-phase lines with a high degree of precision and accuracy. The PW3198 is a power quality analyzer for monitoring and recording power supply anomalies, allowing their causes to be quickly investigated, and also for assessing power supply problems such as voltage drops, flicker, harmonics, and other electrical issues. • PW3198 (main unit only) • PW3198-90 (PW3198 PQA bundled with the PQA-HiView Pro 9624-50) Note: Voltage can be measured with the main unit alone. An optional current sensor is necessary to measure current or power parameters. Use the PQA-HiView Pro 9624-50 (version 2.00 or later) with a PC to analyze the data collected to the SD card.

3-Channel AC/DC Power Meter for Single-Phase to 3P4W Equipment such as Motors, Inverters, Power Conditioners, and Power Supplies Hioki benchtop power meters and power analyzers are best in class power measuring instruments for measuring single to three-phase lines with a high degree of precision and accuracy. The PW3337 series measure power on the full range of electrical equipment, from single-phase devices such as battery-driven devices and household electronics to industrial use and three-phase electrical equipment over 3 input channels. The power meters provide coverage from DC to inverter frequencies with support for voltages up to 1000 V and direct-input currents of up to 65 A, and can also measure currents of up to 5000 A using an optional current sensor. PW3337 (basic model) • PW3337-01 (with GP-IB) • PW3337-02 (with D/A output) • PW3337-03 (with GP-IB and D/A output)
