Absolutely correct. Very few of those I have been connected with are "clean" for RFI, and 
those few were especially designed to be "RF Quiet".

Another way you may consider "boosting" the current capability of your 24 V supply is by (as 
Charles mentioned) paralleling the supply with a HUGE bank of very-high-capacitance 
capacitors. Several thousand MFD worth each. Those are usually pretty cheap on places like 
eBay since low-voltage, high-capacity capacitors are not particularly popular.

And they would all have to be connected together with some pretty "fat" wire.

In any case, as Chris mentioned, the highest output voltage of that supply is still, really, too 
low. That should be 28.8 VDC at least.

Personally, I would be looking for a better solution to your issues.
