Maretron’s Alternating Current Monitor (ACM100) provides information about the AC electrical system including voltage, current, frequency, and power. This intermediate system, which ships with one current transformer, is used to monitor a single phase shore power connection (or any other AC source – generator, invertor, etc.), and if for any reason the boat becomes disconnected from the shore power, then a text message is sent to notify someone of the condition.
The following table shows the products included within this example system plus a list of the information or data available for display.
| Product | Description | Available Data List |
| DSM250 | Display | Displays data in this list, monitors the data and sounds an internal buzzer if there is a problem |
| ACM100 | Shore power monitor | Monitors voltage, current, frequency and power |
| SMS100 | Texting module | Sends text messages to one or more phone numbers when any monitored data in this list goes outside programmed limits |
This file requires Maretrons free NMEA 2000® network design tool N2KBuilder® to be installed on your PC.
