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.</div><div><br></div><div>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. </div><div><br></div><div><ul class="MailOutline"><li>Does anyone know of a latching solenoid that will work with a 12v hi/lo voltage state,</li><li>OR an interface or circuit for hi/lo to control latching relay</li><li>OR a solenoid with a very low quiescent current when on? </li></ul></div><div><br></div><div>Many thanks in advance, </div><div><br></div><div><div apple-content-edited="true">Larry Crutcher<br><div><br><br><br><br></div>
