Depending on load current. You may want to consider using a low on
resistance N mos fet as the switching element. <br>
There is almost no stand operating current.<br>

Hello Wrenches,
<div><br>
</div>
<div>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.</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>
