AEMC 3945 Power Pad Three Phase Power Quality Analyzer PQA - NIST Calibrated

  • The AEMC 3945 Power Quality Analyzer has full color graphical display lets you see and analyze volts, amps and harmonic content in real time and take pictures to document and analyze clearly. Its high speed sample rate, at 256 samples per cycle, provides excellent fidelity in reproducing waveforms and capturing transients that happen as fast as 62.5µs.

    The AEMC 3945 PowerPad’s 4MB of memory is conveniently partitioned to let you store four different types of data, synchronized or independent of each other. You can store up to 12 screen snapshots, up to 50 captured transients that contain four cycles for each active input, and 4096 alarm events. You can also record trend data for days, weeks or even months.
