Single Phase Power Meter Compatible with DC Measurement and Current/Power Integration Measurement
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 3334 is an AC/DC power meter that measures inrush current and power consumption, ideal for DC and current and power integration applications to meet energy efficiency standards.

For equipment that uses rectifiers and control devices, it might not
be possible to accurately measure voltage or current without an
AC/DC power meter.
• Half-wave rectified waveforms used for dryers and fans
• Full-wave rectified waveforms used for AC adapters
• Cycle control waveforms used for voltage and temperature
adjustment heaters
• DC waveforms with superimposed ripple components
