Set it up as a split-charge relay, a battery-protect relay or an engine-start protect relay, depending on what your system needs.\u003c\/p\u003e\u003cp\u003eAn ordinary relay burns power the whole time it is closed, which can eat most of what a small solar panel makes. A latching relay locks its contacts in place and only needs a short pulse to switch, so Sterling rates this control circuit at about 0.5mA. That matters when solar or wind is topping up your batteries with the engine off.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThree operating modes: split charging (one-way or both-way), battery protection, and engine-start protection\u003c\/li\u003e\n\u003cli\u003eAutomatically selects 12V or 24V: powers up as 12V below 16.5V and as 24V above 17V\u003c\/li\u003e\n\u003cli\u003eFactory-preset trigger points that can be fine-tuned with a magnetic swipe (useful for lithium banks): 'on' 10.4V to 15V, 'off' 10.0V to 14.6V (double for 24V)\u003c\/li\u003e\n\u003cli\u003eBuilt-in starter disengage circuit opens the relay while the starter cranks, protecting it from the current surge\u003c\/li\u003e\n\u003cli\u003eCharge mode can trigger from whichever side reaches the trigger voltage first, or one direction only\u003c\/li\u003e\n\u003cli\u003eBattery-protect mode gives a warning before cutting power: off for 10 seconds, then back on for 1 minute so you can start the engine or a charger\u003c\/li\u003e\n\u003cli\u003eNo limit to the number of battery banks you can charge\u003c\/li\u003e\n\u003cli\u003eOptional LRR remote (sold separately, 5 m cable) shows input or output voltage, high-voltage trip alarm at 16V (32V on 24V), relay status, 1-minute emergency override and a mutable alarm; Sterling says the remote is needed to reset the relay after a battery-protect trip\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e LR240\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem voltage:\u003c\/strong\u003e 12V or 24V, auto-selected\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous current:\u003c\/strong\u003e 240A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax intermittent current:\u003c\/strong\u003e 1500A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuiescent current:\u003c\/strong\u003e 0.5mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput stud:\u003c\/strong\u003e 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable 'on' trigger:\u003c\/strong\u003e 10.4V to 15V (x2 for 24V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable 'off' trigger:\u003c\/strong\u003e 10.0V to 14.6V (x2 for 24V)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGenuine Sterling Power with Sterling Power's warranty.
