Prolongs battery life by preventing battery damage.NeWNeWFeatures & Benefits• Overcurrent, short-circuit and over-temperature protections offer safe and reliable operation.• Eliminates contact wear and extends service life to = 1,000,000 On-Off cycles.• Resistant to vibration and mechanical shock. • Withstands contamination from moisture, dust and salt spray.• Draws minimal quiescent current of 2mA.• Pre-disconnect warning is provided by a visual or audible alarm (sold separately). • Built-in “snooze timer” allows one hour override (factory programmable).• Automatically disconnects non-critical loads from a battery when the battery voltage falls below a predefined threshold. Automatically reconnects the loads to the battery when the battery is being charged. Automatically prevents the loads from disconnecting during starting. An optional ignition override input is also provided.• Manual override option permits a user to make or break the connection, regardless of the battery voltage. (Switch sold separately.)• Environmental: -40°C to 85°C. SAE J1455 & J1113• Electrical: 150A or 200A continuous. Inrush: 500A (for 5 seconds). 2mA max quiescent current.• Ignition-proof to ISO 8846.• Disconnects when battery drops below 12.1V for 2 minutes, reconnects when battery meets or exceeds 13.0V for 10 seconds. (Factory programmable)• Alarm: Active low, 50mA. Activates 1 minute before disconnect. (Factory programmable) • Accuracy: ±100mV• Electronics sealed to IP67.SpecificationsLow Voltage Disconnect SwitchMomentarySwitchIgnition Switch12V 50mA LED and/or BuzzerVIOLETWHITEORANGEBLACKLoadBattery+–48512 150A 12V48510 200A 12V
