It appears to be equiped for class 1 or class 2 operation as seen in the photo that offer two plugs for such.
In ther second photo, on top it shows three items, the main plug and right under that is 20V 60Hz 5.5A. The second and third pictured items are two fuses and the first is a 4A SB and the second is a 3.2A SB.
The photo on the buttom of that pic is of 4 plugs. The first 3 white plugs are marked as follows, under the word "CLASS 2": the first is SYNC, the second is OUTPUT 24V DC 3A. The last is 12V DC 3A. The red and black one to the right says, 12V DC 20A CLASS 1.
I know little about power suplies but I believe this one was bought to be used in a Hospital for a communications system.
I have purchased a large quantity of electrical items and on many of the boxes it says it is for a school or Hospital. I could not find much on the internet either.
