Measure AC/DC Standby Power Up to Large Power Loads

  • Ultra-sensitive standby power measurement Measure according to IEC 62301 DC, or 1P2W Max. input 1000 V, 30 A


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 PW3335 delivers high measurement accuracy and handles currents with higher crest values in lower current ranges (i.e., high crest factors) while minimizing the effects of power factor to greatly help reduce power measurement uncertainty, especially critical when the measured standby power is at μA levels.
