The 3104 is a 300A integrated solenoid and control module for 14V systems. The unit features a biostable solenoid that can remain open or closed without a coil current draw. The unit can be utilized in four different modes of operation based on settings of jumpers external to the unit.
- Voltage : 12 Volts
- Amperage : 300 Amps
- Approx. Weight : 2 Pounds
Modes of Operation
Listed below are the many different functions of this product.
Unidirectional Battery Separator : 300 Amp
This mode is used to charge two batteries from one power source. In this mode, the unit monitors the "main" battery. When the main battery voltage is above the connect threshold, the solenoid connects the two batteries together. When the main battery voltage drops below the disconnect threshold, the solenoid is opened. In this mode, the connect threshold is usually set to a voltage that is only reached when the charging system is operational. This will cause the solenoid to only close when the charging system is operational, charging both batteries. The RCM pin must be grounded in a battery separator application.
Bidirectional Battery Separator : 300 Amp
This mode is used to charge two batteries from two sources. In this mode, both batteries are monitored. If either battery is above the connect threshold the unit will close the solenoid. If the batteries are below the disconnect threshold the unit will open the solenoid. The voltage settings for the bi-directional battery separator remain the same as the unidirectional battery separator. The RCM pin must be grounded in a battery separator application.
Low Voltage Disconnect (LVD) :
In this mode, the unit monitors the battery voltage. When the battery voltage drops below the disconnect voltage, the unit opens the solenoid, removing power from the load. The solenoid closes, powering the load.
Isolator / Interconnect Mode :
This mode is used to charge two batteries from one power source. This mode provides the advantages of both the isolator charging system and the battery interconnect.
