Reginald,
Actually, I think you are outside of Class 2 limits
with 24 Vac 5 A, as the limits of Class 2 are maximum
30 Vac / 42.4 Vdc, maximum 8 A and maximum 100 VA.
Your power supply is over the 100 VA maximum.
That does also mean you are outside the UL 1310 limits
(Standards for Class 2 power units). I am not that
familiar with all the different UL requirements for
power supplies, but I did some digging around on
www.ul.com and found the following possibility:
Standard - UL 1012: Power Units Other than Class
2
Category - QQFU: [Power Supplies] Power Supplies,
General Purpose.
Hope that helps,
-Camille Good
Portland, Oregon
