Heat problem in CG-1500 case
« on: October 15, 2014, 10:03:31 AM »
How are folks handling heat buildup in your CG-1500 cases?  I have a CG-1500 with 2-350 watt power supplies and a Falcon F-16 board.  With the box shut and no lights running the temp.  Inside the box the temp runs about 80-85.   This is a 72 basement.  I suspect this would work in the outdoors with a cooler ambient temp at night.  I was testing another feature, got distracted and left the lights on on the mega tree!  Ran for awhile and then I heard a pop and half the lights went.  Opened the box and one power supply was off and very hot.  I assumed the power supply would shut down based on the specs from Rays web site.
 High-temperature protection   ERH3>=65C~70C Fan on,<=55C~60C Fan off,>=80C~85C,Cut off output(5~15V)Cut off output(5~15)~(24~48V)
The way I reads this is that the unit should shut off all output power at about 176!  I am letting it cool down to see if it resets.  Sure hope so.  That pop has me worried.
Next day
The power supply did not reset.
I am at a loss as to what to do.  One thought would be to put the two power supplies in separate  boxes and leave the F-16 board in the CG-1500 box.
Thoughts and suggestions appreciated.

You may want to check this setup out - http://www.diychristmas.org/vb1/showthread.php?2433-Two-Power-Supplies-in-a-CG-1500

I think you're still going to have heat issues but this may get you by...

I too had this heat issue with the power supplies and chose this year to use the rainproof sealed power supplies which I mount outside the box. but yes for sure they do need good ventilation and installing fans in the box is a good idea a well.

also had this heat issue with the power supplies, now I been adding two Plastic-Louver vent on my Enclosure,
one is smaller for air in-take and the bigger one for the output of the fan of the power supply..

this the link from I order the Plastic-Louver vent  http://www.ventmyhouse.com/categories/Round-Soffit-Vents/Plastic/

Her are a couple of pics I posted on the DIYC forum a couple months ago. I was concerned about heat in my CG-1500 case so I installed a small fan in the door with a small circuit to turn on the fan when it reached a certain temperature.

I put my supplies in a battery box external to the CG1500. No problem with heat at all. I used 12ga power cord to connect the supplies over to the F16 board.

That's the route I am considering.  Did you use a fan?

Hmmm didn't notice heat issues with mine, but they are outside and non sealed power supplies. Maybe I just didn't notice..



This is one 12v and 1 5v PS, I was not pushing them that hard either..

No fan. The Marine battery boxes seems to have enough airflow without them. As always it never hurts to have an extra fan, but the fans in the power supplies themselves keep the air circulating fairly well.
