PQA 2300

What has long been standard practice for incoming material inspections now safeguards your electrical supply: The PQA 2300 – The precise incoming inspection for your power quality

The Power Quality Analyzer PQA 2300 is a high-performance Power Quality Analyzer designed for the continuous monitoring, analysis, and documentation of power quality in three-phase low-voltage networks. It measures all relevant electrical network parameters, detects critical power quality events at an early stage, and helps ensure reliable, efficient, and uninterrupted operation of your electrical systems.
With its integrated web interface, comprehensive communication interfaces, and standards-compliant power quality analysis, the PQA 2300 integrates seamlessly into existing FRAKO Energy Management Systems. This gives you complete transparency over your power supply, allowing you to identify disturbances before they result in costly downtime.
