It seems all the answers are for DC power. I thought the question was for
24V AC. At least that is how it read in the subject..
Any changes to the comments

I am thinking if it is possible to connect the source input to the surge
tester to a DC source, instead of the AC source, then you can apply the

Just one guy's opinion.

Hi Jennifer,
I would argue that the test should not be applied that port, simply because
that port is fed from a 24V supply upstream. It is perfectly reasonable to
specify in the product documentation that the supply upstream must meet the
requirements. Why make the compliance process more
Jennifer,
I have instructed those clients I deal with to test the input as follows:
Get a transformer thats typical for your unit, and apply the surge to the
input of it. Keep the leads short.
By doing this you have made an attempt to met the standard. And, yes I know
it's not perfect, but it
I am thinking if it is possible to connect the source input to the surge tester
to a DC source, instead of the AC source, then you can apply the surge tests to
the DC input of your product.
