Hot Topic - My Power Pack

I had a problem with my 2500 tripping off from overheating even though it was not feeding more than the nameplate load. My solution was a bit drastic, but I've never had a problem yet! Probably ended up doubling the effective capacity of the power supply. <br /> <br />I installed a cooling fan. If you open up the unit you'll find a transformer and a main circuit board with a cheap-o sheet of aluminum for the heat sink. Doesn't work worth squat inside a sealed up plastic box to cool the electronics. My solution was to install a 1" diameter fan from Radio Shack on one side near the top / back side, and then drill 1/8" holes around the bottom for air inuts. I cut a 3/4" hole behind the fan for exhaust. The fan is powered by the 12VDC output. The higher the setting the faster the fan. The fan is very quiet under most conditions. <br /> <br />I've since bought a second fan and have another PS to retrofit as well. <br /> <br />Definately NOT something for the faint in heart to do! <br /> <br />Mark in Utah
