Paralleled MAIN and SATELLITE in a non-isolated configuration. The power train of both MAIN and SATELLITE Power

Stamps is inherently isolated; the power path isolation can be shorted on the motherboard in non-isolated

applications. Optional digital isolators can provide isolated feedback and isolated input telemetry.
