Power Standards Lab: Announcing: The PQube 3 Family

Came over the email transom this week:


We are pleased to let you know that we announced the commercial availability of two new PQube® 3 models.The range of PQube 3 analyzers now includes:

  • PQube 3 – ultra-precisee multi-function and multiple-circuit power quality and energy meter. Ideal for immediate diagnosis of power issues, power consumption analysis, as well as environmental sensing, and external process monitoring
  • PQube 3e – multi-load powerr consumption monitoring for 14 single-phase loads, or 4 three-phase loads measured simultaneously; drastically lowering the per-circuit cost of monitoring
  • PQube 3v – voltage quallity analyzer; ideal for price-sensitive applications where compliance is required, while load monitoring is not

Features of the PQube 3 analyzers include:

  • Ultra-compact form factor; fits virtually anywhere – ideal for embedding (DIN-rail)
  • Detection and recording of high-frequency impulses at 4 MHz
  • Measurement of 2 kHz – 150 kHz emissions (first instrument on the market to cover the entire frequency range)
  • Four analog and multiple current channels (up to 14 on PQube 3e)

Benefits of using the PQube 3 analyzers include:

  • No learning curve – very intuitive, with no software needed
  • PQube 3 generates information you can immediately use – disturbance and trend graphs sent directly to your iinbox
  • Additional channels and embedded sensors provide a precise set of measurements covering the power side, plus process monitoring, and environmental parameters
  • Measurements can be used for verification requirements; PQube 3 is certified Class A IEC 61000-4-30 Ed3, and is ANSI Class 0.2/0.2S revenue-grade accurate
  • Optional enterprise software enables fleet maintenance and data aggregation

I’ve been a fan of PSL Founder Alex McEachern from back in the BMI days; have not had a lot of opportunity to work with the PSL devices / technology. To be honest, without an on-staff or on-call power guru (like me) to help sort out signal from noise, the technology seems a little hard to use / parse for the layperson. But cool as hell, from a power quality perspective….
