Product Details

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.

Technical Specifications:

  • Display: Organic LED (OLED) digital screen
  • Monitoring Functions: DC voltage/current, AC voltage/current/frequency, bilge pump activity, tank levels
  • DC Voltage Range: 7-70V DC (nominal 12V, 24V, 48V)
  • AC Voltage Range: 40-300V AC (nominal 120V, 230V)
  • DC Current Range: -500A to +500A
  • AC Current Range: 0-150A
  • Frequency Range: 40-90Hz
  • Current Draw: 18.8mA @ 12V (backlight off), 35mA @ 12V (backlight on)
  • Battery Bank Inputs: 2 (one with current monitoring, one voltage-only)
  • Bilge/Tank Inputs: 2 configurable inputs

The M2 Vessel Systems Monitor consolidates multiple gauges and monitors into one space-saving unit, reducing installation complexity while providing at-a-glance status of your vessel's most critical systems.

This was the easy part, with the exception that once I was in the CART area it wouldn't let me go back to add a quart to my order of a gallon, try as I may...

OK

Great price, quick easy checkout.

Good prices, easy ordering.
