Power Supply for ACA

I’m looking for a linear power supply for an ACA. Or even better, a single power supply(or 2 in one chassis) for a pair of ACA’s. Several on aliexpress, but none that are 60w/5a like the switching adapter that came with them.

I’m not entirely interested in building one as the parts seem to cost as much or more as a completed unit. Any suggestions on sizing or specific units would be appreciated. Thank you.
The ACA is powered by a 24V/5A (120W) power supply, not a 60W.

I don’t know this seller but here’s an example although it’s a bipolar dc output
