Fast & Reliable
The Acuvim 3 advanced power quality meters are engineered to provide high-precision power quality metering plus revenue grade, IEC Class 0.1S/ANSI C12.20 Class 0.1 (active energy) four-quadrant power monitoring. With support for synchrophasor applications, it can record real-time power quality disturbances, like dips, swells interruptions, unbalance, flicker, and transients as well as capture critical waveforms triggered by sub-second power quality events. Its enhanced Fast Log capture feature can generate and send reports, providing critical information to mitigate the impact of damaging power quality issues. Compact and robust, this advanced power quality meter features a wide range of flexible communication protocols plus an easy-to-use interface with advanced user management and security.
