12V automatic battery isolator controller/monitor/alarm
Automatic Low Voltage Battery Disconnect and Alarm Module. 12V 75amp version.
Manufactured by INTRA technologies
Protects 12V battery systems from damage through excessive discharge. Automatically disconnects auxiliary loads leaving enough charge on the main batteries for vehicle starting.
Summary description: An intelligent battery monitor and automatic alarm and battery disconnect switch - all in one module. Protects 12V vehicle or alternative energy battery systems from excessive discharge by first activating an alarm signal and then automatically removing an auxilliary load circuit from the battery. The built in solid state switch can handle up to 75amps continuous loading. Automatic timer control allows the INTRA disconnect to ignore momentary voltage drops for example those caused by motor starting surge currents [e.g. fridge compressor start-up].
From the manufacturers pdf: "The Intra Battery Power Manager an intelligent, low-cost switch that allows you to run creature comfort electrical components without the risk of exhausting your battery. You preserve enough power to restart your engine reducing your need for a jump-start.
The smart switch Using patented Intra Switch technology, Intra s BPM monitors voltage levels from your battery automatically turning off power to non-critical loads when battery voltage reaches a critical low point, then reconnecting power when voltage returns to a safe level.
Rugged and reliable with solid-state construction and no moving parts, Intra s BPMs are designed for long life."
Current Ratings: 75 amps @ 70 C
Voltage Drop Across the Switch: Less than 0.15 volts at 75 amps and 25 C ambient..
Current Draw: Less than 8 milliamps in normal operation.
Alarm Wire: 6-foot, 22-gauge with attached remote alarm.
Low Voltage Disconnect: If the Override input is not active and the RS voltage is below 12.1V for 60 seconds, the Low Voltage alarm will initiate for 10 seconds. Every 60 seconds the alarm will reannunciate for 10 seconds. At 5 minutes the alarm will sound for 30 seconds. After 5 minutes 30 seconds, the switch will disconnect the load.
Reconnect: The switch automatically reconnects the load after the RS voltage rises above 12.8V for 10 seconds or if the override terminal is energized.
