Features

  • Electrical Performance
    • Universal line voltage 90–265V AC, 45–65 Hz for use anywhere, and is compatible with low voltage power sources
    • AC input range will continue to produce reduced DC output to as low as 75V AC
    • Power factor corrected for efficient charging
  • Advanced Multi-Stage Charging
    • Output for three 12 Volt battery banks
    • Charge profiles for Flooded, Gel, Thin Plate Pure Lead (TPPL), and Absorbed Glass Mat (AGM)
    • A user configurable charge profile is available for other battery types
    • PreFloat stage prevents over charging by individually moving each battery out of the Absorption charging stage, so batteries near full charge do not receive the high constant voltages necessary for other batteries still in the Absorption stage
    • Charge Coordination integrates with up to two Blue Sea Systems Automatic Charging Relays (ACR) to separate the battery banks while the P12 is operational
  • Built In Safety Features
    • Over and under temperature protection for batteries
    • Overheat protection
    • DC over voltage protection
    • DC reverse polarity protection
    • Surge and short circuit protection
