Handheld PQ Analyzer
Model: Model: PQA-500
The Power Quality Analyzer PQA-500 is an advanced handheld 3-phase analyzer. It is a highly intuitive analyzer that has capability to view RMS data, waveforms, demand data, phase angles, harmonics, unbalance, flicker and more in real time.
The Handheld PQ Analyzer PQA-500 has features which make it ideal for troubleshooting, compliance testing and energy audits. Auto CT identification eliminates potential errors due to wrong CT range settings. The analyzer will automatically identify the CT and verify it is connected correctly.
When data needs to be recorded, the built-in flash memory of PQA-500 can simultaneously store 60 sets of screen shots, 150 sets of transient voltage/current capture waveforms, 12800 sets of alarm logs, and the start current detection mode can continuously capture 100s of the start current waveform. The built-in 2G memory card is used to store long-term trend curve records and record 20 electricity parameters at the same time (optional). It can collect and record the trend curve records for up to 300 days once every 1 minute.
