Description
Hioki PW4001 Analyzer for Portable, High-Precision Power Testing
The Hioki PW4001 Analyzer is a next-generation portable 4-channel power analyzer designed to meet the exacting demands of vehicle testing, R&D, and production line evaluation. Combining high-precision measurement with portability, the PW4001 is ideal for testing xEVs, DC-DC converters, motors, and inverters in the lab, on production lines, or in real-world driving conditions.
Precision and Reliability Across Applications
With ±0.04% basic accuracy at DC and full measurement bandwidth up to 600 kHz, the PW4001 Analyzer captures even transient power changes accurately. Its millisecond-level data updates and 2.5 MHz sampling allow engineers to analyze motor efficiency, inverter losses, and battery performance with unprecedented detail. Auto phase shift correction ensures current sensor measurements remain accurate, while the direct voltage input supports up to 1500 V DC for versatile testing scenarios.
Field-Ready Design
Designed for on-road testing, the PW4001 Analyzer operates from −20°C to +50°C and supports DC power supply from 10.5 V to 28 V, making in-vehicle installation straightforward. CAN and CAN FD inputs allow real-time acquisition of battery voltage and other vehicle data without modifications. Its compact clamp current sensors simplify installation even in tight engine spaces while minimizing risk of sensor damage.
Optimize Testing Workflow
The PW4001 Analyzer reduces setup time during drive range and efficiency testing by enabling flexible placement near the vehicle, expanding channels with synced units, and allowing safe, direct connection to CAN bus signals. Its combination of waveform visualization and numerical data ensures accurate, quantifiable measurements for both research and mass production, fully compliant with WLTP and SAE J1634 standards.
