NAI’s iPM is an Intelligent Power Monitor that provides a precise, instrument grade, digital analysis of input power lines. This advanced, DSP-based unit monitors single-phase, 3-phase 4-wire wye, or 3-phase Delta power lines at various input voltage levels and frequencies.

The iPM is equipped with an EIA RS485-compatible serial communications interface that permits additional control functions and readout of diagnostic data, and features a Background Built-In-Test (BIT) that constantly monitors the health of unit hardware and software. This power monitor is designed and qualified to the most stringent performance and environmental requirements, and is ideally suited for rugged defense and industrial applications.
