Product Details

The Egis Mobile Electric Single XD is an advanced battery management relay system with NMEA 2000 connectivity and manual override knobs. This intelligent relay eliminates dead start batteries by automatically sharing charging across two batteries while isolating them when no charge sources are present, making it ideal for marine vessels, RVs, and specialty vehicles.

Key Features:

  • Heavy-Duty Performance: 500A continuous / 1600A cranking current capacity supports all standard marine and RV electrical systems
  • Bullet-Proof Construction: Sealed to IP67/IP6K9K rating with high-temperature electronics and materials for mounting anywhere
  • Intuitive Manual Control: Knobs provide manual override with clear indication of locked on/off states
  • Space-Saving Design: 35-75% reduction in mounting space and product weight compared to traditional relay systems through advanced bi-stable solenoid technology
  • NMEA 2000 Integration: Network connectivity for system monitoring and control
  • Simple Programmability: Dip switch configuration allows flexible setup for various applications
  • Expandable System: Compatible with Link and Cross-Link Busbars to connect additional Dual, Triple, or Single XD Relays for 2 or 3 battery systems
  • Marine-Grade Hardware: Stainless steel cable lug studs and large mounting holes accept 1/4-20 / M6 hardware
  • 4-Position DT Connector: Deutsch connector for reliable, weatherproof electrical connections

The Single XD Relay represents a significant advancement in battery management technology, combining intelligent charging control with robust construction suitable for harsh marine, RV, and mobile environments.
