Kussmaul Auto Isolator I Controller

High Efficiency, No Diode Drop. Eliminates Diode Isolator in a 2 or 3 Battery System

• Actuation Voltage: < 13.3V (field adjustable)
  Battery Load: 0.000125A
  Output Current: 3A
• System consists of a controller that detects when a vehicle’s alternator is charging the main battery and then closes a solenoid to tie-in charge to an auxiliary battery
•  When the engine is off or the charge voltage is no longer present, the solenoid opens to isolate the batteries
• Upon “cranking” the engine with a charged auxiliary battery, the solenoid is energized to parallel the batteries and provide a starting boost
• If the auxiliary battery is low, the controller senses that condition and the batteries are not paralleled
• Uses a solenoid rather than an isolation diode which typically causes a 0.7V drop, thus auxiliary battery receives full charge voltage
• The starting boost provided by the paralleled batteries is especially useful in
  cold weather or when the battery is low.
