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.

Hello everyone,
        I am currently trying to test a product of ours that falls under 50082-1
generic standard for light industrial equipment.  Our problem is that we
have a 24VAC power input port.  The generic standard calls out for EN
61000-4-5 on AC power input ports.  After looking at EN 61000-4-5 it seems
that it is intended for AC mains voltages, but I couldn't find anything that
says a 24VAC input is exempt from this test.  I am looking for outside
opinions on whether this test is truly applicable.

Thanks,
Jennifer Banh

BTW, we already tried just testing to the spec, and failed.  Any suggestions
on how to protect against this test would also be appreciated.
