Testing Hypex UcD modules?

I have a 4x Hypex UcD 180LPV8 that I salvaged from an old amp. Those old amps had some problems which I do not think related to the modules themselves but then again, not 100% sure.

In full disclosure, I write the following from a fairly high level of ignorance so this may be a stupidly simple question.

I'm considering ordering the Hypex SMPS400A180 (matching power supply) to put together a 4-channel amp with the modules. Before I go to that trouble I would like to test them to make sure they actually work. I assume that I could use a 20V laptop power adapter to power them up for this test?

According to the 180LPV8 datasheet, they will run on voltages from 20-50V.
