In digital mode the C7042 will supply 5 Amps continuous and up to 8/10 Amps for approx 2 seconds before overloading. In two lane analog mode I would expect, but have not measured, things to be the same. In other words a total of 5 Amps continuous or 8 Amps for approx 2 seconds, the current being available on a total basis to the 2 lanes.
This is because the voltage from the two supplies is combined and then fed to the output stages. In digital mode the 2 output stages are connected in parallel with a relay and in analog mode they are operated separately one feeding each lane. However the current monitoring takes place at a single point after the voltage dropper / regulator and before the two output stages. So the Powerbase does not know how much current is going to each lane, only the total.
On S-H yes the 8 amp limitation is the rating of the relay, in practice more current can be take without failure. However I have always strongly advised this in order to protect the long term reliability of the S-H setup. Which I have to say is excellent,
there are probably somthing in the order of 500 S-H units scattered around the World and the couple of failures that I know of were all due to the PSU being connected up the wrong way round.
