EGIS MOBILE ELECTRIC XD Triple - Flex 2 - (Relay)-(ACR)-(Relay) with Knobs Replaces Three Individual High Amp Relays with one 500 Amp Compact Module, reducing space significantly, eliminating the cost of external link cable connections, eliminating the risk of link cable connections vibrating loose, and providing clear, unambiguous awareness of how operate manual controls and what state the manual controls have forced the relay into. Designed to Replicate Common Multi-Battery Switching and Charge Management Functions: Common dual-battery load switching via the outer relays, and a central automatic charging relay to share charge current, are easily implemented. Multiple Automatic Charging Relay (ACR) Into One Device: For 3-4 Battery Systems that require 2 or 3 ACRs, a single three-relay ACR provides a significant reduction in off-state quiescent current draw and space usage, while eliminating unnecessary interconnection cables. Expandable with Link and Cross-Link Busbars to Additional Dual, Triple, or Single XD Relays: Supports 3 or 4 battery systems with standard busbar interconnect accessories.
