The PMI Bolt™ compact power quality recorder is purpose-built for fast deployment, accurate diagnostics, and modern wireless power quality monitoring across utility and industrial applications.

Its ultra-slim design makes it the ideal meter base power quality recorder, fitting easily into enclosures where bulkier systems fail. This enables efficient capacitor bank controller monitoring, transformer analysis, and field troubleshooting without additional mounting hardware.

As a true RMS power monitor, the Bolt captures voltage, current, and power data across 3 channels, delivering high-resolution waveform capture power quality, harmonic analysis to the 51st order, and standards-based flicker monitoring (IEEE 1453 / IEC 61000-4-15). It functions as both a harmonic analyzer and voltage sag recorder, allowing users to diagnose power disturbances and verify power quality compliance monitoring requirements.

The Bolt also excels in real-world applications, including VFD power quality troubleshooting, identifying the root cause of flickering lights, and supporting EV charging station power quality studies and distributed generation testing.

Built-in Wi-Fi and Bluetooth provide instant access as a wireless power quality monitor, while the optional Cell Bolt adds LTE for full remote power quality monitoring—eliminating truck rolls. Data is automatically stored and accessed through PQ Canvass, enabling seamless cloud power quality recording and analysis.

With its NEMA 4X power recorder design, LED-guided installation, and line-powered operation, the Bolt is an affordable power quality analyzer for electric utilities that delivers reliable performance in any environment.
