Egis Mobile Electric 7612-24 Triple Battery Advanced Automatic Charging Relay ACR 24V

The Egis Mobile Electric 7612-24 is a 24-volt Triple Battery Advanced Automatic Charging Relay (ACR) designed to manage charge sharing and isolation across three separate battery banks. By combining two independent ACRs into a single compact unit, it eliminates the need for multiple discrete devices, reducing installation space, wiring complexity, and potential points of failure.

This ACR automatically shares charging between all three batteries when a charge source is detected, and isolates them when no charge source is present—protecting your start battery from being depleted by house or auxiliary loads. With an ultra-low off-state current draw of just 1.3 mA (compared to 7–10 mA for typical dual-ACR setups), the 7612-24 significantly reduces parasitic drain in three-battery-bank systems.

Key Features:

• Two Independent ACRs in One Device – Reduces installation space, time, cost, and points of potential failure across a three-bank system
• Ultra-Low Off-State Current Draw – Only 1.3 mA quiescent draw, approximately 90% less than running two separate ACRs
• Prevents Dead Start Batteries – Shares charge across all three battery banks and isolates them when no charge source is present
• Fully Sealed with Integrated Connector – Sealed Molex MX-150 / Deutsch DT-compatible connector eliminates corrosion and vibration-related connection failures; includes DT04 harness for plug-and-play assembly
• Bullet-Proof Construction – Sealed unit with high-temperature materials and integrated thermal overload shutdown protection; mountable in virtually any location
• Adjustable Off-Voltage for Auxiliary Battery Priority – Allows sharing of start battery energy for auxiliary loads without compromising engine starting ability
• Start/Engine Isolation Input (Optional) – Protects sensitive electronics from voltage sags and spikes during the cranking event
• Start Assist Input (Optional) – Combines battery banks to maximize available cranking amps when needed
• Optional Under-Voltage Lockout – Prevents a healthy battery from being connected to one with a shorted cell, protecting the entire system
• Additional Low-Amp Output – Can be used to report device status remotely or drive a secondary relay
• Top-Side DIP Switches – Accessible after mounting for programming voltage settings and feature selection; protected by a self-retained cover
• LED Diagnostics – Provides indication of relay ON/OFF status, under-voltage, over-voltage/temperature, start isolation/assist, and output state
• 4-Year Industry-Leading Warranty
