Vanner model 52-75 has been designed to meet the requirements for the 12 Vdc medical outlets stated in section 3.7.7.3 of the GSA specification KKK-A-1822D. 250 Amp Dual Battery Smart Isolator Universal 12V 24V Voltage Sensitive Relay Intelligent Dual Battery Isolator For Car Truck Atv Battery Starter Controller. To prevent voltage spikes and surges caused by turning the battery switch off while the engine is running, please follow the GSA recommended wiring diagram on the reverse side. A Schottky diode reduces the loss by one-half of a typical silicon diode. Vanner battery isolators operate on both 12 and 24 volt DC electrical systems.Īs current passes through an isolator, the diode type affects the voltage loss across it. This is desirable in many vehicles where more power is required, and is mandated on ambulances that must meet the GSA's specification KKK-1822-D. Function: 250Amp battery isolator is a primary battery saver, which used to combine two batteries when an alternator is charging (engine running) and isolate them when not charging (engine off) so you can still start your vehicle. Schottky battery isoltors are designed to reduce the voltage drop across the isolator's terminals, allowing a higher voltage, or charge, to be delivered to the battery. Both types utilize a special heat sink design for excellent heat dissipation and heavy-duty wiring terminals. Vanner manufactures both silicon and Schottky type battery isolators. With a battery isolator operating in the system, the power would not be taken from the engine's battery, keeping it fully charged. Voltage Sensitive Relay designed with samll size, portable and compatible for a wide variety of vehicles as 12V/24V Jeep, Truck, SUV, RV, Caravan & Camping. ![]() With the engine off, the DC to AC inverter could continue to operate, discharging the second battery. 12V-48V High Current Master Battery Disconnect Switch Kit,250A Continuous. With the engine running, the alternator will supply charging current to both batteries. Dorman Conduct-Tite Battery Isolator Switch - 85988 Part : 85988 Line: CTI. Due to the isolator's ability to pass current in only one direction, your first battery can be discharged without draining power from the second battery.įor example, a typical vehicle system may use one battery dedicated to the engine (starter, ignition, etc.) And the other battery dedicated to a DC to AC inverter. Vanner battery isolators allow dual batteries to be charged from a single power source such as an alternator or battery charger.
