Portable 4-channel power analyzer with ±0.04% basic accuracy for vehicle power measurement
The PW4001 is a high-precision, portable 4-channel power analyzer that offers Hioki’s highest-ever DC accuracy of ±0.04%. Additionally, its measurement bandwidth extends up to 600 kHz, with accuracy specifications maintained across this entire frequency range, ensuring reliable performance from DC to high-frequency applications.
POWER ANALYZER
Model:
PW4001
Maker:
HIOKI
Lab-grade precision, Field-ready
From xEV fuel and energy consumption testing to DC-DC converter and inverter efficiency evaluation, as well as motor efficiency analysis, the PW4001 provides exceptional reliability and versatility, making it a new-generation portable power analyzer designed for a wide range of measurement scenarios.
Engineered for the tasks you face, wherever you work
Capture transient power changes with high precision
Evaluate motor and inverter efficiency with 1 ms data updates and 600 kHz bandwidth. Even transient power losses are measured accurately.
・Capture motor power fluctuations with millisecond precision
・Evaluate efficiency for high-frequency inverters
・Automatically detect charge and regeneration to calculate efficiency
Reduce setup time in drive range testing
Ensure accurate measurements even at -7°C. With direct CAN voltage input and flexible, vehicle-side installation, test setup is faster and safer.
・Accuracy maintained at -7°C. Install directly in cold chambers
・Use a compact setup near the vehicle and expand channels with synced units
・Acquire battery voltage via CAN, safe and simple
Use it on the road Designed for real-world driving tests
Measure power without vehicle modification. OBD-II input and 10.5 V to 28 V DC power supply make in-vehicle use easy.
・Operates from −20°C to +50°C, ready for harsh environments
・Run on DC power for easy in-vehicle installation
・Use OBD-II CAN bus for safe, real-time vehicle data acquisition
Ensure production quality with waveforms and numbers
Combining waveforms and numerical values ensures reliable, quantifiable quality in mass production.
・Verify efficiency with ±0.04% accuracy at DC and 50 Hz/60 Hz
・Direct voltage input up to 1500 V DC
・2.5 MHz sampling enables waveform evaluation of switching events
Half the Size, Maximum Precision
The slim design clamp current sensor ensures easy installation even in tight spaces.
Complex tasks in the engine room become simple and efficient, dramatically reducing preparation time for fuel efficiency and performance testing. Not only does it reduce setup time, but it also minimizes the risk of sensor damage from forced clamping between narrow spaces.
Fully compliant with the WLTP and SAE J1634 standards, it provides precise AC/DC current measurements up to 200 A with an impressive DC accuracy of 0.07%.
IEC-Compliant Harmonics and Flicker Measurement (PW9006 Option)
Add IEC-compliant harmonic analysis and flicker measurement functions to the PW4001.
Available for online purchase with same-day license issuance from “Drivers, Firmware & Software” on the PW4001 webpage.
Note: Requires PW4001 firmware version V1.10 or later.
