Is this the same as Daikin's Altherma range?

No. Altherma is Daikin's hydronic (water-based) heat pump range for radiators and underfloor heating. This Premium Inverter Ducted system is a ducted air-based reverse-cycle system for space heating and cooling.

Does this need three-phase power?

Yes, this specific model runs on 380-415V three-phase supply, so it is only suitable for homes with three-phase power already connected or budgeted for as part of the install.
