Product Details

The Blue Sea Systems M2 OLED DC Voltmeter (1833-BSS) is a professional-grade digital monitoring solution designed for marine, RV, and renewable energy electrical systems. It accurately measures and displays DC voltage across up to four independent battery banks on a single, large OLED screen — making it an ideal choice for complex multi-bank electrical setups.

The auto-dimming organic LED display automatically adjusts brightness to ambient light conditions, ensuring easy readability in both bright sunlight and low-light environments. The meter operates over a wide input voltage range of 7–70V DC, making it compatible with 12V, 24V, 36V, and 48V battery systems.

Key Features:

  • Multi-bank voltage monitoring — measures and displays DC voltage for up to four battery banks
  • Auto-dimming OLED display — bright, high-contrast 55mm x 28mm screen adjusts to ambient lighting conditions
  • 80dB audible alarm — user-programmable high and low voltage alarm thresholds to protect batteries from over- or under-voltage conditions
  • Isolated 500mA MOSFET relay — controls external circuits based on measured voltage values
  • Wide input voltage range — operates from 7–70V DC, compatible with 12V, 24V, 36V, and 48V systems
  • Voltage measurement range — 8 to 70V with 0.01V resolution and ±1.0% accuracy
  • Low power consumption — variable 0.3W–1.0W draw depending on voltage, display intensity, and sleep mode
  • Easy to adjust — intuitive interface for programming alarm thresholds and display settings

With overall dimensions of approximately 3.24 in. x 3.24 in. and a compact display profile, the M2 integrates cleanly into standard panel cutouts. Blue Sea Systems engineers this meter for long-term reliability in demanding marine and mobile power environments.
