<DIV><SPAN class=609182515-22092008>In my experience, relays are simple and
reliable solutions, especially the 30A open-coil type. I would suggest the
MX60's LVD auxiliary function to control a 12V DPST open-coil relay with a 12V
coil (Grainger 5Z556). To add additional protection against long-term arcing
causing contact pitting, series or parallel the contacts.</SPAN></DIV>

<P class=MsoNormal>Hello all,<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I have an application where a customer has a continuous
40watt load in a remote location (similar to telecom). <o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>We are looking at the MS-60 or MX product for charge control,
but neither of these has a LVD without using additional relay
equipment.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>The charging current coming in from the panels (if we are
forced to stay with 12V) is right at 60 amps.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>To get the low voltage disconnect function, do you see any
problem going with multiple PS-30M charge controllers, and using just one of
them for the 40W load?<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>Thanks,<o:p></o:p></P>
