What does "Class 2" Transformer/Power Supply mean?...

[kidvybes]

...I'm in need of replacing a power source for one of my rack mounted CD players, and the original power supply was rated "12volt 2.5amp/Class 2 Transformer"...I find that there are many replacement power supplies available with 12v/2.5a, but none say "Class 2" on the specs...does anyone know what the Class 2 specification means?...I googled it with no luck...thanks!

Here: "....What is a Class II transformer?
A Class II transformer is inherently limited to not more than 60 watts. It is a low energy device and
considered intrinsically safe. Secondary wiring from a Class II transformer does not require conduit and
clamp wiring techniques..."

from here:

All commercial power supplies that you would be using for the device would be class II. You don't have to worry if it passed UL and it is rated for 60 Watts or less.

Google search done!

...so then I can assume that any 12v/2.5a (or higher amperage) power supply, like those commonly used for LCD monitors would be safe to use?...sounds good...thanks for the clarification..

Yes you can... just be sure your tip and sleeve polarity match...

you might want to check to be sure it IS a DC and not AC adapter... given the amperage it could well be AC...

...yes...definately DC...the original charger looks "old school" (the CD player is about 5 years old) compared to the newer more common LCD monitor power sources...that may explain the "class 2" designation, which I never see on the newer power adaptors/wall warts...
