Description
Overview
The Hioki PW3337-01 is a multi-channel power analyzer designed for comprehensive power measurement across single-phase devices (battery-driven and household electronics) to industrial three-phase electrical equipment. With three input channels, it measures power from DC to inverter frequencies (0.1 Hz to 100 kHz) at voltages up to 1000V and direct-input currents up to 65A. The model includes a GPIB interface for remote control and data acquisition. The PW3337-01 processes RMS values, mean values, DC components, AC components, fundamental wave components, harmonic measurements, and integration data in parallel internally, with simultaneous true-time measurement capability.
