EGIS™ 12V Automatic Charging Relay (ACR) 160A. Eliminates dead start batteries by sharing charging on either of two batteries and isolating batteries when no charge sources are present. Supports multiple engines or independent charge systems by incorporating two independent start or engine isolation inputs to allow isolation of charge sources when both are active to maximize charging performance. Protects electrical system cascading faults with optional lock-out from closing if one terminal is connected to a battery with a shorted cell. Sealed unit, stainless steel hardware, high temperature materials allow mounting anywhere with bullet-proof construction. Integrated thermal overload shutdown protection.
