| Battery Isolators These heavy duty isolators allow charging multiple batteries automatically from one or two alternators, and prevent discharge or 'dumping” of one battery into another. Each battery is charged according to its need without overcharging. rated for 12-48 volt negative ground DC systems. feature conservatively rated diodes and a rustproof anodized aluminum heat sink case. Models are available for 70, 120 and 165 amp alternators. |

Performance Specifications
Operating temperature: -40 to +80° C
Duty cycle: Continuous rating to 50° C Derate linearly to 70% @ 80° C
Temp. rise: 5° C at full rated current (mount vertically for optimum cooling)
Voltage drop: 0.7V @ 50% load, 0.9V @ full load
Note: These battery isolators are not compatible with self exciting alternators. Please consult the manufacturer of your alternator if you are unsure of your configuration.
The Battery Integrator causes no voltage drop in the charging system, while the multiple batteries are charged as a single bank whenever a charging source of approximately 13.2 VDC or 26.4 VDC or greater is present (depending on model).
When the alternator or charger is off or a large load causes the voltage to drop below the disconnect point the unit breaks the common tie between the banks. This allows selective battery discharge and prevents “dumping” of a higher-charged bank into a lower-charged bank. The unit may also be activated to connect other batteries through the key starter or a manual switch to provide an added “boost” from the secondary battery whenever the starter is engaged and the unit senses there is sufficient voltage in that battery to provide an assist.
For systems with more than two banks, an isolator must be installed for each additional bank to provide the same isolation and integration as described above.
Features
• Enables charging of two separate banks without voltage drop, yet maintains 100%
isolation at all other times. For systems of three banks or more, an additional unit must
be installed for each additional bank
• Heavy duty silver-plated contactor, continuous duty rated to 100 amps
• Voltage sense circuit, epoxy encapsu- lated and heavy duty continuous rated solenoid are
all designed for use in marine environments
• 12 volt model has ignition protection rating
• Easy three-wire hook up for two bank systems (BATT +, BATT +, GROUND)
• Terminal for optional wiring of remote light indicating when battery banks are integrated
• Optional internal connection can be wired though key starter or manual over ride switch, tying
battery banks together for extra boost during engine start

The Battery Integrator is ideal for expanding the single charging output of an inverter-charger to maintain both the house bank and an engine start bank, then to isolate them during inverter function, so current is drawn from the house bank only.
