AC Systems Monitor from 80 to 260 VAC 100A

NMEA2000 AC Monitor
Compact AC monitor with NMEA2000 interface

AC Systems Monitor connects to an AC Shore Power or to your generator to measure AC Voltage, AC current, AC Frequency, AC Power.  The AC Systems Monitor has one AC voltage input and one Current Transformer input.

The unit comes with 0-100A current transformer with split core, which allows for very easy installation without the need to disconnect the existing AC wires.


The unit’s NMEA2000 network input is optically isolated from the Main’s power lines. Please refer to and follow your local electrical code requirements when installing.
