The \u003cstrong\u003eBlue Sea AC\/DC Vessel Systems M2 Monitor VSM\u003c\/strong\u003e consolidates essential data from your DC battery banks, AC power supply, bilge pumps, and fluid tanks into a single, space-saving unit. Featuring a high-contrast \u003cstrong\u003eOrganic LED (OLED) digital display\u003c\/strong\u003e, this marine system monitor delivers exceptional readability across various lighting conditions, from bright midday sun to night-time navigation.\u003c\/p\u003e\u003cp\u003eEngineered for demanding marine environments, the M2 VSM provides boat owners and marine technicians with real-time visibility and early warning alerts. By replacing standalone voltmeters, ammeters, and tank gauges with one integrated module, you reduce dashboard footprint while improving situational awareness on the water.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll-in-One System Visibility:\u003c\/strong\u003e Simultaneously tracks DC battery health, AC shore or generator power, bilge pump activity, and fluid tank capacities.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Contrast OLED Screen:\u003c\/strong\u003e Bright, crisp digital readout navigated via weather-resistant tactile control buttons.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Battery Bank Tracking:\u003c\/strong\u003e Comprehensive State of Charge (SoC), voltage, and current tracking for a primary bank, plus voltage monitoring for a secondary bank.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfigurable Audio\/Visual Alarms:\u003c\/strong\u003e Customisable high and low alerts for electrical thresholds, tank levels, and excessive bilge cycling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNMEA 2000 Certified:\u003c\/strong\u003e Integrates directly into your existing marine network backbone using standard connectors without proprietary cabling.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eComprehensive DC and AC Power Management\u003c\/h3\u003e\u003cp\u003eProtecting your marine electrical system from deep discharge or irregular shore power is vital for onboard safety and equipment longevity. For DC systems, the primary input measures voltage, current, and State of Charge (SoC) for your main house battery bank, while a secondary input tracks the voltage of an auxiliary or starter battery. Configurable alarms alert you to high or low voltage, high current draw, and low battery status before permanent cell damage occurs.\u003c\/p\u003e\u003cp\u003eOn the AC side, the unit monitors a single AC supply for voltage, current, and frequency. Whether connected to marina shore power or an onboard generator, customisable alarms for voltage drops, current overloads, and frequency deviations help safeguard sensitive AC appliances.\u003c\/p\u003e\u003ch3\u003eIntelligent Bilge and Tank Inputs\u003c\/h3\u003e\u003cp\u003eThe M2 Monitor features two versatile auxiliary inputs that can be independently configured for either bilge pump or fluid tank monitoring:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBilge Monitoring Mode:\u003c\/strong\u003e Goes beyond simple on\/off indicators by logging active pump activity, cycle counts over the last 24 hours, average daily cycles, and total lifetime cycles. High-priority alarms can be set for excessive run-time minutes within the last hour or abnormal cycle frequency, providing early detection of slow hull leaks or faulty float switches.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank Monitoring Mode:\u003c\/strong\u003e Displays fluid levels in litres, gallons, or as a percentage of total capacity. Unlike standard gauges that struggle with irregular hull contours, the M2 VSM allows custom tank shapes to be programmed or auto-calibrated for accurate volume readings, complete with high and low level alerts for fuel, freshwater, or greywater tanks.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSeamless NMEA 2000 Integration\u003c\/h3\u003e\u003cp\u003eDesigned for modern marine electronics architectures, the Blue Sea 1850B is \u003cstrong\u003eNMEA 2000 certified\u003c\/strong\u003e. It connects directly to a shared NMEA 2000 network backbone using standard connectors, eliminating the need for complex point-to-point wiring looms. Furthermore, it supports function sharing with compatible multi-function displays, including CZone Touch 5 and Touch 10 interfaces, allowing you to view system data across your vessel.\u003c\/p\u003e\u003ch3\u003eUpgrade Your Helm Station Today\u003c\/h3\u003e\u003cp\u003eStreamline your dashboard and protect your vessel's vital electrical and plumbing infrastructure.
