<div dir="ltr">Yes, with the 24V fan, you will need to run battery power (or another 24VDC source) through the contacts. That's the reason I opt for 12V vent fans typically, so they can be served with the 12VDC Aux source from the charge controller.</div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Jan 7, 2015 at 3:26 PM, jay peltz <span dir="ltr"><<a href="mailto:jay@asis.com" target="_blank">jay@asis.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="auto"><div>The router version magnum remote has a dry contact relay</div><div>ME-RTR</div><div><br></div><div>Jay</div><div>Peltz power. </div><div><div class="h5"><div><br><br><div><br></div></div><div><br>On Jan 7, 2015, at 10:56 AM, Ray Walters <<a href="mailto:ray@solarray.com" target="_blank">ray@solarray.com</a>> wrote:<br><br></div><blockquote type="cite"><div>
<div>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>
