Hello Wrenches, We're preparing to offer Lithium batteries to some of our customers as a replacement to lead acid in recreational vehicles. RV batteries can have multiple charge sources simultaneously so I have worked out protective circuitry to interface with a EMS computer. To insure failsafe operation, I need to install 2 solenoids that will be active 24/7, opening only when fault conditions are met.
The solenoids I have looked at (200 amp) have a coil current of about 1 ampere each which equates to 600Wh daily consumption. I'de like to reduce that BUT the computer only provides a +12v or 0 volt state. Does anyone know of a latching solenoid that will work with a 12v hi/lo voltage state, OR an interface or circuit for hi/lo to control latching relay OR a solenoid with a very low quiescent current when on? Many thanks in advance, Larry Crutcher
