Blue Sea Systems 1850 M2 Vessel System Monitor OLED Display

The Blue Sea Systems 1850 M2 Vessel Systems Monitor provides comprehensive monitoring of four critical marine electrical systems in one compact organic LED digital display. This advanced monitoring solution combines DC power, AC shore power, bilge pump, and tank level monitoring into a single, easy-to-read interface.

DC System Monitoring: Monitor up to two battery banks simultaneously. The primary input tracks DC voltage, state-of-charge, and current flow for one battery bank, while the secondary input monitors voltage for an additional bank. Programmable alarms alert you to high and low voltage conditions, excessive current draw, and low battery states.

AC System Monitoring: Tracks shore power or generator performance by monitoring AC voltage, current draw, and frequency on a single circuit. Configurable alarms warn of dangerous high or low voltage conditions, excessive current, and frequency irregularities that could damage sensitive electronics.

Bilge and Tank Monitoring: Two versatile inputs can be configured as either bilge pump monitors or tank level sensors. In bilge mode, track pump activation, cycle counts over 24 hours, average daily cycles, and total lifetime cycles. Set high alarms for excessive run time or cycle frequency to detect potential flooding. In tank mode, display levels in gallons, liters, or percentage of capacity. The system supports custom tank shapes through auto-calibration or manual programming, with adjustable high and low level alarms.
