EGIS Programmable Triple-Battery ACR 160A 12V

The EGIS 7612 is a TH3-Series dual automatic charging relay (ACR) for 12V electrical systems, rated 160A total or 80A per circuit (240A / 120A intermittent). It uses two independent charge relays with a single ultra-low-power monitoring system to share charging across three battery banks and isolate them when no charge source is present, preventing dead start batteries while reducing off-state quiescent current by up to 90% in three-bank systems.

An ultra-low off-state current draw of 1.3mA (versus 7-10mA on typical ACRs) means it will not deplete batteries during extended downtime. A fully sealed enclosure with integrated connector solves control-wire corrosion and vibration issues and enables plug-and-play assembly, while stainless-steel self-locking hardware and high-temperature materials allow mounting almost anywhere. An optional under-voltage lock-out prevents combining with a battery that has a shorted cell, and start/engine isolation and start-assist functions are individually selectable per relay. Voltage thresholds are set via top-side dip switches, LED diagnostics report status, and the unit ships with a Deutsch/Amphenol DT connector harness with Molex MX-150 and wire-lead options.
