Information on class 2 power supply.?
*Class 2 compliance requires a maximum power output availability
of less than 100 watts for the component. Class 2 defines the
portion of the wiring system between the load side of a Class 2
Power Supply (beginning from the outside of a cabinet or machine)
and the connected equipment. Due to its power, current and voltage
limitations, a class 2 circuit considers safety from a fire
initiation standpoint and provides acceptable protection against
electric shock. *Only the load side of a power supply with a
nameplate rating of less than 100VA (or 5 times Vout if output
voltage is lower than 20V) can meet the class 2 circuit
requirements.
