I'm just wondering if there's any glaring problems with this design which I have overlooked. The basic idea is to use a relatively large resistance to limit the inrush current to the transformer and reservoir caps. Once the caps charge to a specified voltage, relay RL1 closes, bypassing the resistor array. Then at some slightly higher voltage RL2 closes, connecting the load to the caps.
RL2 is necessary in order to ensure the supply voltages come up with a fast edge and reach their specified levels at roughly the same time, otherwise one of the micros can be pretty temperamental. I know without RL2 (ie. load always connected) the res caps would never be able to reach a sufficient voltage to close RL1 (not with such a large ballast resistance at least), and from my understanding this is one of the reasons inrush current limiting for the transformer and res caps is advised to be handled separately.
The only other issue I can see (vs. existing valid designs) is overload protection in the event RL1 fails to close; which is overcome easily enough with the addition of F2.
Is there anything else I should be worried about? (Never mind about particular component values, or the relay coil charge/hold circuitry - it may prove over simplistic as drawn, but I plan to cross that bridge after I select which relays to use).
