The Hioki PW333601 measures 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 2 input channels. The power meter provides coverage from DC to inverter frequencies with support for voltages up to 1000 V. The PW333601 model comes with a GP-IB input installed.

Measurement accuracy that remains unchanged for high-current measurement

Accuracy is guaranteed for currents of up to 65 A with direct input. The PW3336-01 can also measure high currents in excess of 65 A with optional current sensors. Direct-input power meters typically exhibit degraded accuracy when inputting high currents due to shunt resistor self-heating. However, the PW333601 reduces input resistance with a DCCT design that virtually eliminates this type of accuracy degradation.

Simultaneous processing of power data and all harmonic data

All data, including RMS values, mean values, DC components, AC components, fundamental wave components, harmonic measurement, and integration measurement, is processed in parallel internally. There is no need to switch modes depending on whether you wish to acquire power data or harmonic data - simply switch the display to obtain measured values with true simultaneity. Additionally, PC communications software can be used to capture measurement data, including from multiple synchronized instruments.
