1 Introduction
Congratulations on your purchase of the Maretron Alternating Current (AC) Monitor (ACM100).
Maretron has designed and built your ACM100 to the highest standards for years of
dependable and accurate service.
Maretron’s ACM100 is a device which monitors AC power sources and outputs information
about these sources onto the industry standard NMEA 2000
®
marine data network. ACM100
output information is then displayed with networked NMEA 2000
®
equipment such as the
Maretron DSM250 dedicated display or with NMEA 2000
®
compatible software such as
Maretron N2KView. The ACM100 can sense voltages up to 240VAC (line-to-neutral) and
currents up to 200A.
The Maretron ACM100 is designed to operate within the harsh demands of the marine
environment. However, no piece of marine electronic equipment can function properly unless
installed, configured, and maintained in the correct manner. Please read carefully and follow
these instructions for installation, configuration, and usage of the Maretron ACM100 in order to
ensure optimal performance.
