I would like 48V from 2 x Mean Well DRP 480 24V used for a Texas TPA 3255. Is it just to connect in series?

Add a reverse bias diode to the output terminals of each power supply is to prevent reverse voltage if one power supply starts up before the other and also to protect the power supplies during short circuits.
The diode must have a current rating of at least twice the output current and a reverse voltage rating of twice the output voltage.

Is there a reason not to use the SDR-960-48 which produces 48V at 20A in one unit without need for heat-sunk large diodes?
