New Purasan install

[thoward]

Background-Preparing for new 12V Purasan install which will plumb to a freshwater 32V Vacuflush system. I would like to trigger off the 32V vacuflush system as well. Primary Purasan electrical and trigger both must be 12V. I have 12V at generator and 32V house/engine. I spoke with Raritan and they suggest a pair of new Marine Elegance heads. Maybe, but I have been super happy with my Vacuflush. Either way, the underlying electrical issue exists.

Is it better to step down the primary through a 32V-12V 20A regulator or pull off generator system?
Has anyone installed the trigger off the Vacuflush system? I am contemplating a 32V-12V 3A converter.
What is the general consensus of Raritan vs Vacuflush heads?

I went with the Rarutan Freedom with lever flush, no electrical connection required. Short run of hoses directly to the holding tank no low spots.

You should be able to use a contactor with a 12v coil and have the 12v side actuate the contactor and make up the 32v .Or vice versa.

I can't find the link, but they also carry an inexpensive 10 amp (360 watt) converter. I have one operating a 12 volt Atlantes Freedom head and it works great.

Sorry I meant to say 30 amp. Not wide awake yet.
