This is still an experimental build, it may work perfectly first go, or it may require some modifications, especially at very high power. I will incorporate a Peak DC input current trip circuit for each power board, each with an over-current Latch and LED indicator, the outputs of each will feed the Nano Controller Master over-current Latch. I will do the Same for AC current trip on each Toroid, each using an AC current transformer and associated Latch and indicator, again feeding the Master over-current latch on the NANO Controller.   Why? 1: I want to know which Power board tripped over-current.   2: I want to know if AC or DC current tripped the Controller, and from which Toroid AC output. 3: Switching between LOW-HI power mode (1 or 2 power boards) requires no change with respect to DC or AC over-current protection adjustments/settings. It will take all the time wasting setup, calibration and hassles of working out what tripped the over-current and why, and allow full monitoring of DC input balance between the two Power boards. _
