high temperature in an enclosure or something so battery voltage wouldn’t be a good indicator. We have military and vehicle applications that use +12 or 24v to the fan via an adjustable t-stat. Check Grainger under HVAC t-stats, this one is around $25<o:p></o:p></span></p>

<p class="MsoNormal">The Magnums do not have relays available like the old SWs, but you can run a Zephyr directly from either a Outback FM controller or a Midnite Classic. Both have a controlled 200 mA, 12 output. I've had occasional trouble running the Zephyr
because as weird as this sounds: the fan can have a start up surge that exceeds 200 mA. Its like sizing a water pump for mice.....you still have to look at the locked rotor current and surge current. With the Midnite Classic, it will just shut off the 12
v output if it exceeds 200 mA, and it doesn't seem to have an error message or warning.<br>
You could also use a Simple Switch, or other voltage controlled switching device (C40, Tristar, Solar Converters, etc)<br>
