The ATR has a "power management system". Consists of settings for T/off, MCT, and Cruise.
PL's set into a detent, the "notch", and power settings controlled thereafter by the PMS switch.
The PL's are retarded out of the notch on descent to control speed, all the way down to landing.
Re electrics, cant remember exactly, 2 DC gens and 2 ACW gens that can power DC systems via TRU's. Good level of redundancy but as to a direct comparison to the Dash - dont know.
Only DH product I've flown was the twotter, and that was BLARDY MARVELLOUS!!
