You don't need to do anything. The Amps rating listed on a power supply is the maximum amount of current (Amps) it can safely deliver continuously, NOT the amount of current it will deliver.

Whatever you're supplying with 48 volts will draw whatever number of Amps it uses, and the 48V power supply will not try to force more current/Amps through it.

The electrical receptacles in my home provide 120V at up to 15A. But my clock draws a current of only 2mA (0.002A) from the 120V.
The clock will NEVER draw the available 15A.
