Its job is to stop a battery bank being ruined by over discharge. It wires in series in the load leg between the battery and the load, with a separate small gauge sense wire running directly to the battery terminal so it reads true terminal voltage rather than voltage depressed by load current.\u003c\/p\u003e\u003cp\u003eWhen the battery falls to the disconnect setpoint the internal contactor opens and drops the entire load, halting the discharge before the cells suffer permanent capacity loss. It holds the load off, drawing only its own small standby current, until a charge source brings the bank back up to the higher reconnect setpoint, at which point it closes again automatically. The gap between the two setpoints is what prevents the relay chattering on and off as the bank sags and recovers. Both setpoints are adjustable on potentiometers reachable through the cover.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e Newmar Powering the Network\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eModel:\u003c\/strong\u003e LVD 12-30\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e LVD 12-30\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAlternate Part Number:\u003c\/strong\u003e 490-1230-0 REV A\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct Type:\u003c\/strong\u003e DC low voltage disconnect, battery over discharge protection\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNominal System Voltage:\u003c\/strong\u003e 12 V DC, negative ground\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMaximum Continuous Current:\u003c\/strong\u003e 30 A\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFactory Disconnect Setpoint:\u003c\/strong\u003e 10.4 V DC\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFactory Reconnect Setpoint:\u003c\/strong\u003e 12.2 V DC\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDisconnect Adjustment Range:\u003c\/strong\u003e 10.4 to 15 V DC\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReconnect Adjustment Range:\u003c\/strong\u003e 9 to 15 V DC\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQuiescent Draw, Load Connected:\u003c\/strong\u003e 0.30 A\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQuiescent Draw, Load Disconnected:\u003c\/strong\u003e 50 mA maximum\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTerminals:\u003c\/strong\u003e Studs with supplied ring lugs, 2 x quarter inch for input and output, 1 x number 10 for sense\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSense Circuit Protection:\u003c\/strong\u003e 1 A fast blow fuse\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIndicator LEDs:\u003c\/strong\u003e None\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAlarm Contacts:\u003c\/strong\u003e None\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMounting:\u003c\/strong\u003e Wall, bulkhead or mobile via case flanges, horizontal or vertical\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eEnclosure:\u003c\/strong\u003e Vinyl clad aluminium, electrically isolated case\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e 0 to +50 degrees C\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e Approximately 133 x 133 x 89 mm (5.25 x 5.25 x 3.5 in)\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eUnit Weight:\u003c\/strong\u003e Approximately 0.45 kg\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSerial Number:\u003c\/strong\u003e 17260012\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBarcode:\u003c\/strong\u003e 729198676087\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e United States of America\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e New, in the original box\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eProtects a 12 V battery bank from deep discharge damage\u003c\/li\u003e\n\u003cli\u003eBoth disconnect and reconnect setpoints adjustable on board\u003c\/li\u003e\n\u003cli\u003eSeparate sense lead reads true battery terminal voltage under load\u003c\/li\u003e\n\u003cli\u003eAutomatic reconnection once the bank recovers, no manual reset\u003c\/li\u003e\n\u003cli\u003eLow 50 mA standby draw once the load is disconnected\u003c\/li\u003e\n\u003cli\u003eRugged vinyl clad aluminium case, isolated so it can mount on metal or timber\u003c\/li\u003e\n\u003cli\u003eRing lugs and insulating boots supplied\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTypical Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOff grid and standby solar battery banks\u003c\/li\u003e\n\u003cli\u003eRemote telemetry, radio and telecom sites on 12 V DC\u003c\/li\u003e\n\u003cli\u003eMarine, RV and mobile 12 V systems with an auxiliary battery\u003c\/li\u003e\n\u003cli\u003eAny 12 V load that must be shed before the battery is damaged\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Includes\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e1 x Newmar LVD 12-30 low voltage disconnect\u003c\/li\u003e\n\u003cli\u003e2 x quarter inch ring lugs for input and output\u003c\/li\u003e\n\u003cli\u003e1 x number 10 ring lug for the sense connection\u003c\/li\u003e\n\u003cli\u003eRubber insulating boots\u003c\/li\u003e\n\u003cli\u003eNo cabling, battery or mounting hardware is included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eAdditional Information\u003c\/h2\u003e\u003cp\u003eA low voltage disconnect is battery protection, not load protection.
