Re: camtronics driver

Hi Al
From my experience with similar drivers, it is OK to use the same enclosure
as long as you apply some simple rules of good design. Keep the transformer
and any high power bridge rectifier (get quite hot) a reasonable distance
away from the driver (5" is good) and allow for good ventilation of the
power section (without making it easy for swarf, metal dust and any coolant
spalsh to get in. A fan near the power section would be a good idea too.
If your space is very tight, a peice of sheet metal or copper clad PCB board
used to seperate the power supply and electronics would not hurt.
The large smoothing capacitor(s) for the power supply should not be exposed
to high temperatures so don't put it next to the bridge rectifier - high
temps will shorten its life.
If you think along those lines you should end up with a reliable setup.
