Description
Maretron ACM100 Alternating Current (AC) Monitor – ACM100-01
The Maretron ACM100 AC Monitor (ACM100-01) brings powerful alternating current power monitoring to your boat’s NMEA 2000® network, giving you real-time insight into your vessel’s shore power, generator output, and onboard AC systems. Designed for seamless integration with Maretron displays and software like N2KView®, the ACM100 turns critical AC electrical metrics into network data that can be viewed anywhere on the vessel with compatible NMEA 2000® interfaces.
Whether you’re managing a generator, monitoring utility power, or tracking multiple AC busses on a large yacht, this monitor provides comprehensive electrical data — not just basic voltage and frequency — to help you diagnose power issues, optimize system performance, and protect your electronics from unexpected power anomalies.
Key Performance Features
-
Comprehensive Data Tracking: The ACM100 monitors all critical AC parameters, including Voltage, Current (Amps), Frequency (Hz), Real Power (Watts), and Reactive Power (VARs).
-
True RMS Measurement: It uses True RMS technology to provide accurate readings even on distorted waveforms, which is common when running off older generators or modified sine-wave inverters.
-
Total Energy Monitoring: The module calculates Energy Used (kWh) over time, allowing you to track exactly how much power your vessel is consuming during a trip or while docked.
-
Advanced Safety Diagnostics: By monitoring the relationship between voltage and current (Power Factor), it can help identify inefficient equipment or potential electrical issues before they cause a failure.
-
Plug-and-Play Network Integration: Data is broadcast over the NMEA 2000 bus, making it viewable on any compatible display like the Maretron DSM410 or a standard chartplotter.
