(Update 12/1/2012) I have used this power supply on several fishing/camping trips to power my Koolatron electric cooler for 3-4 days at a time. Other power supplies burned out quickly, this thing will get hot and shutoff before it burns itself up. I added a 120 mm dc fan to the top of the power supply with a glue gun. Wired the fan to the black and red power hook ups on the front of the unit. Since I've done that I haven't had it overheat on me once. This power supply is heavy but it's a tank and it's lasted me!
The fins on the back of the converter do get pretty toasty but it doesn't seem to bother the unit. Last time I used it at in-laws I borrowed a small fan and blew it on it for the whole 5 days we visited. No problems.
The converter seems to be well-built. It weighs a ton and doesn't have any problem running a thermo-electric cooler.
My setup is such that I may run it at my home, or several times a year I set up a portable observatory in a remote location where all power comes from batteries at night, charged by day from an array of solar panels on my motorhome.
Due to the dependence on battery and solar, I monitor my power usage very closely. All of my components run on DC power through a RigRunner distribution, and I always run with an accurate power meter measuring total current through the RigRunner. From this, I know that my average current draw is just under 5.6 amps to run the mount, camera, focuser, rotator and laptop during image capture. My selection of this power supply was based on it being rated for about double my typical load.
Since purchasing the power supplies, they have run successfully, but rather hot. It seems that they are not very efficient, which is not a huge problem running off of line power at my house.
The bigger problem is that I just had one of these units fail in a bad way. I was working at the telescope when the power supply started buzzing. At the same time, I heard a number of audible warnings from some of the other equipment. The laptop switched to its internal battery from the 12 volt supply. I checked the power meter and noticed that the power supply had jumped to 19.8 volts.
Fortunately, none of my equipment was damaged and I was able to get it running again by switching to a pair of big AGM batteries and rebooting everything.
I am very unhappy that the power supply could fail in a way that resulted in an over-voltage. This could have been a very expensive event (well into the tens of thousands) had some of the equipment been damaged. It's also fortunate that I was present at the time of the failure. Most of the time, this gear runs unattended.
The power supply that failed no longer works properly, and I refuse to use the other one after seeing this problem.
I am now searching for a power supply that gives me some level of confidence that even if it fails, it will fail in a safe way.
