It is for boats, RVs, vans and trucks that need the alternator or a charger to feed a second battery bank, such as house, windlass or bow-thruster batteries.\u003c\/p\u003e\u003cp\u003eIt needs no ignition wire in its default mode: when it sees more than 13.3V, it assumes a charging source is running and joins the batteries, then separates them again when the voltage falls so house loads cannot drain the starter battery. By default it works in both directions, so a single-output inverter\/charger on the house bank can also top up the engine battery. A starter-motor interlock keeps cranking current out of the relay, and spark suppression helps protect the contacts. For banks that may see loads far beyond the relay rating, Sterling recommends a current-limiting relay instead.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFully automatic voltage-sensing operation, no ignition feed needed by default\u003c\/li\u003e\n\u003cli\u003eThree modes: engine-side activation, bi-directional (default) or one-way with ignition feed\u003c\/li\u003e\n\u003cli\u003eAdjustable connect and disconnect voltages\u003c\/li\u003e\n\u003cli\u003eAutomatic 12V \/ 24V selection\u003c\/li\u003e\n\u003cli\u003eVery low voltage drop (about 0.01V)\u003c\/li\u003e\n\u003cli\u003eWaterproof to IP65 and SAE J1171 ignition protected\u003c\/li\u003e\n\u003cli\u003eBack-EMF spark arrester and suppression diodes\u003c\/li\u003e\n\u003cli\u003eSingle and twin starter-motor disengage connections\u003c\/li\u003e\n\u003cli\u003eQuiescent current about 1 mA\u003c\/li\u003e\n\u003cli\u003e5-LED display with 5 alarms and safety trips\u003c\/li\u003e\n\u003cli\u003eEmergency forced connection and high battery voltage trip\u003c\/li\u003e\n\u003cli\u003eShort circuit protection before engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous rating:\u003c\/strong\u003e 80A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem voltage:\u003c\/strong\u003e 12V or 24V, auto select (4-16V locks to 12V, 16-30V locks to 24V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnect voltage:\u003c\/strong\u003e Above 13.3V (default, x2 for 24V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection:\u003c\/strong\u003e IP65, SAE J1171 ignition protected\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuiescent current:\u003c\/strong\u003e About 1 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 140 x 180 x 40 mm (5.5 x 7.1 x 1.6 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.1 kg (0.22 lb)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGenuine Sterling Power with Sterling Power's warranty.
