HIOKI PW4001 Portable 4-Channel Power Analyzer
The HIOKI PW4001 is a portable, high-precision 4-channel power analyzer with ±0.04% basic accuracy. The analyzer has a DC to 600 kHz frequency bandwidth and 1 ms data update rate. The device's input rating is CAT II 1500 VDC. The analyzer also supports waveform and D/A output, motor analysis, and external DC power input. The PW4001 features power calculation using CAN values.
- Portable 4-channel power analyzer.
- Basic accuracy ±0.04% across a frequency range from DC to 600 kHz; benchmark accuracy of ±0.03% rdg. ±0.01% f.s. at DC and 50/60 Hz.
- Frequency bandwidth DC, 0.1 Hz to 600 kHz.
- Data update rate 1, 10, 50, 200 ms.
- CAN/CAN FD output and input.
- 16 GH internal memory and USB 3.0 for Flash storage.
- Safety rating CAT II 1500 VDC; supports direct voltage input up to 1500 VDC (CAT II) and 1000 VDC (CAT III).
- Operating temperature range -20...+50°.
- Applications and PW4001 advantages:
WLTP (worldwide harmonized light vehicles test procedure) testing: Excellent DC accuracy.
DC-DC converter efficiency measurements.
Inverter efficiency measurements: Wide frequency measurement band.
Motor efficiency measurements.
Off-grid work: DC-powered (12.5...28VDC) and portability.
Measurements in climate test chambers: Wide temperature range -20...+50°C. - Operation largely identical to PW8002: Quick changeover when needed without a long training period.
