Overview
The Hioki PW8001 is a high-precision power analyzer for motor and inverter efficiency analysis, spanning DC to 5 MHz. Hioki is the only manufacturer that develops both power analyzers and a wide portfolio of high-accuracy current sensors in-house, which allows automatic phase-shift correction and stable measurement even at low power factor.
A single PW8001 measures eight channels of power data and can synchronise up to four instruments over BNC cable (32 channels), or two units over optical link (16 channels / 8 motors). Applications range from SiC/GaN semiconductor characterisation and EV dual-inverter testing to smart-grid and renewable-energy measurement.
Key Benefits
World-class accuracy: ±0.03% basic and 0.2% at 50 kHz. High-speed capture: 18-bit, 15 MHz sampling with 110 dB CMRR. Scales to a bench full of inverters: 8 channels per unit, 32 channels synchronised. Safe high-voltage input: 1500 V DC CAT II / 1000 V DC CAT III.
Applications
Inverter and motor efficiency analysis, SiC/GaN power-device characterisation, EV/HEV inverter testing, smart-grid and renewable-energy measurement, reactor power-loss analysis, and multi-circuit power-interchange systems.
