I tried to set max power using the set screw on side of power supply.

Does the set screw have a max stop or does it turn infinate?

Hello,byteman59.Please do not adjust this fixing screw, it has been set at the factory to limit the maximum current output by the power supply.

Yes, I have moved the screw and now my power supply is not reaching full power.
