Miro PQ45 – 600V Class A Power Quality Analyser & Logger
The Miro PQ45 packaged with rugged holster is a truly robust and professional grade power quality analyser designed for real-world electrical systems and compliance testing. Built to IEC61000-4-30 Class A standards and rated CAT IV 600 V, this compact unit delivers the accuracy and safety you expect for power quality audits, compliance verification, energy studies and detailed waveform analysis.
This isn’t just a data logger ,the PQ45 captures comprehensive measurements across all three phases plus ground and neutral, giving you a clear picture of system performance. It tracks sags, swells, interruptions and flicker, records harmonics and interharmonics, and logs voltage, current, frequency and power metrics with high precision.
Designed to withstand tough environments, the unit is weatherproof (IP66) and rugged enough for outdoor installations, field testing or industrial sites. Onboard communications include Wi-Fi and optional cellular connectivity, so you can access live data or download results without hauling the unit back to the office.
Whether you are resolving customer complaints, validating compliance, performing energy audits, or investigating elusive power quality issues, the Miro PQ45 gives you the confidence of accurate, industry-proven measurement in a portable, durable package.
Key Features
- Certified to IEC61000-4-30, Class A
- Compact design will allow installation in constrained spaces
- AC and DC voltage and current measurements
- Includes a fourth voltage channel, that can be used for e.g. measuring ground to neutral
- Isolated voltage inputs (each channel has its own neutral) facilitate various wiring configurations
- Two temperature channels
- Expansion port allows for system expansion to include additional sensors, input/output controls and custom interfaces which broaden the PQ system platform. For example, interfaces include DGA, Hydrogen and Bushing monitors (Miro Auxiliary I/O Module required)
- Suitable for all weather conditions: rugged, shock resistant, portable and weatherproof (IP66).
- Safety rated to CAT IV 600V
- > 10kV isolation to ground
- > 10kV isolation between voltage channels
- Detachable voltage and current leads
