We'll see what comes out.
PCB samples on the way.

Yesterday I did tests of EPower module under load.
In the original Enterprise power system there are 12V@0.15A and 2 channel of 5V@1A power supply.
The module has three power sources: 12V@0.8A and 2 times 5V@2A.
The limits 12V@1,2A, 5V@2,5A (both 5A+5B @4,5A). This is much more than an original power supply can provide

In the module, I overloaded the 12V output with current 1A and the diode in the step-up converter warmed up a bit (only it).
One 5V output was load with 2A current. Within 10 minutes of work, without a heat sink, the temperature reached less than 40 degrees celsius
I have only one artificial load system, so I did not test both 5V outputs simultaneously, but the single output provides the same power as the entire original circuit.

Now it's time to mount the module in EP.

Mounted.
Stabilizer temperature below 40 degrees Celsius (without heatsink).
The most difficult thing to do is mount the heat sink. The stabilizer is mounted as low as possible, and yet it is slightly higher than in the original.
Maybe it is not very elegant, but I cut the mounting hole and the fragment of the casing and changed the screw to one with a smaller head.

Pins fit perfectly to the fields on the board.
After removing the elements, you need to thoroughly clean the holes from tin. Especially those with a small diameter, under TR2 transistor and 78L12 stabilizer.
From the EP board remain some parts

There is only one small problem. It is not cheap
The cost of parts and PCB is almost 30 EUR (of which more than half are two stabilizer chips LM2679 and LM2585).

Somebody needs ?
I have 9 PCBs yet, but I don't know if they worth assemblies.

I also need one.
