The datasheet says it has a max. efficiency of 98.5%.

So the input current will be at least 1.5% higher. My guess is you will see around 52-53A on the input at 50A output.

The max input current for the new Orion XS is 50A. If the output voltage is higher than the input, the output current will be reduced to respect the input current spec.
