Doesn't look like what you might want...
What are some typical voltage/current combinations for these devices? You need fixed voltages (1 converter for each device to power), or adjustable voltage (that you use for device A, then for device B, then for device C, etc) ? And: what do you intend to use as power source (AC, DC, voltage range) ? Do you want cheapest possible solution, or easiest-to-use option? Can you put together a circuit with regulator, cooling plate, capacitors, coil, whatever, or do you want a ready-made module?
