3Channel AC/DC Power Meter for SinglePhase 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 threephase lines with a high degree of precision and accuracy. The PW3337 series measure power on the full range of electrical equipment, from singlephase devices such as batterydriven devices and household electronics to industrial use and threephase 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 directinput currents of up to 65 A, and can also measure currents of up to 5000 A using an optional current sensor.
