HI Allan and Walt,
I might suggest a Solid State relay instead of a standard unit.
This will work fine on the MX AUX relay, are totally sealed, and very
reliable.
The MX model line is no more, been replaced with the FM 60/80.

Walt,
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.
What's an MS-60?

Hello all,
I have an application where a customer has a continuous 40watt load
in a remote location (similar to telecom).
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.
The charging current coming in from the panels (if we are forced to
stay with 12V) is right at 60 amps.
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?
Thanks,
Walt
