Power quality analyzers monitor multiple 3-phase, single-phase loads

According to EPRI, power quality issues cost U.S. businesses between $120 and $180 billion each year. For the semiconductor industry, this is a huge problem. But with proper detection and reporting, potential PQ problems can be identified and addressed before they impact the bottom line.

 Power Standards Lab Inc. (PSL) announced the commercial availability of two new PQube 3 models: PQube 3e and PQube 3v. They complement the company’s flagship PQube 3 – the industry standard with thousands of units deployed in the field at semiconductor tools; data centers (UPS, PDU); energy (switchgears, transformers, VFD, PV inverters); and medical (MRI, scanners, generators) applications.

The range of PQube 3 analyzers now includes:

• PQube 3 – ultra-precise 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 power 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 quality analyzer; ideal for price-sensitive applications where compliance is required, while load monitoring is not

Like the PQube 3, the newest models offer power monitoring and analysis in an ultra-compact form factor. They are easily installed in sensitive equipment across a range of applications and industries, such as MRI and medical equipment, transportation, aviation, telecom, utility, data centers, manufacturing, semiconductor tools, shipping vessels, railroads, HVAC, and EV charging. All PQube 3 models enable fast and accurate diagnosis of power flow and quality, as well as temperature, humidity, pressure, three-axis acceleration, AC/DC power, and more.

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 inbox
• 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
