PQ Edge Cost-effevtive, scalable power monitoring and analysis for mission-critical equipment
Safeguard Mission-Critical Equipment ,
Against Operational Risk and Downtime
In critical sectors like data centers and medical imaging, the reliability of high-tech electronics is paramount — and it hinges on power quality. Inferior or unreliable power, characterized by transients, harmonics and distortions, can lead to big problems like outages, flicker, equipment damage, inaccurate readings and more.
Enter the PQ Edge Power Analyzer
Designed to alert you to these risks the moment they happen, the PQ Edge™
unlocks visibility into your power quality issues before they become a problem.
When assessing your electric power, the PQ Edge helps ensure poor power quality doesn’t negatively impact your equipment.
