Ok, thanks I appreciate the info, the manuals don't really get into much details of operation.
I entered an offer for $86.00 with free shipping and the offer was accepted.
The converter / psu from it's pics didn't appear to be terribly used, with dust, etc. From the seller desciption the converter has been sitting around.
One thing I thought was odd is part of the sellers description
“Item is used. Item is in good condition. Item may have minor cosmetic imperfections such as scratches/scuffs. Item has a small dent in the grates (please see last picture).
Due to sitting item may need fuses change by the time the item arrives"
I'm uncertain why the seller describes the item as the fuses may need to be changed from sitting?
For anyone interested I found this spec sheet for PM4's
