hmm.... Maybe the regular controller works, for a while, but could eventually overheat.
I used to supply a controller with much higher power output in a metal enclosure but this took up all of my time assembling these so I discontinued it. It was not feasible to produce in quantity and since then I have lost at least 5-6 orders (but I need to sleep)
I have ordered prototypes for a high power controller to replace it. The quality is not the same but hopefully it will do the job and I will be able to make a lot of them. I expect to receive them in a few weeks and if they manage to supply 20 amps continuous without increasing in temperature more than 10C in a steady state, they will pass the requirement, otherwise I have to modify the design and try again. These also have switching regulators to hopefully drop the 15ma standby current down to 3-4 milliamps.
