Re: [VAC] Another Univolt Question

["David B Robertson" <DROBER05@xxxxxxxxxxx>]

One caution about the Statpower Truecharge 20 model.  According to the FAQ
at Statpower's website (http://www.statpower.com/tech4-3.htm),  the
Truecharge 20 must be mounted vertically.  In my 1974 27', there is no way
it could be mounted vertically in the same location that the Univolt was in
(under the rear tub).  Here is a cut & paste from the FAQ:

14) Q. Why should I mount my TRUEcharge 20 vertically versus horizontally?

A. The TRUEcharge 20 has no fan for cooling, but it does have ventilation
holes. If mounted vertically, cool air will enter the bottom vents, be
heated by the charger's internal components, and naturally rise up to exit
the top vents, thereby creating a natural air convection which actually
improves airflow/cooling. This natural "hot air rising" convection will not
occur to the same level if the TRUEcharge is mounted horizontally as the air
will not pass through the length of the unit. The improvement would however
only be noticeable when operating the TRUEcharge at higher currents, and at
elevated ambient temperatures, ie. >90 F / 30 C.
