Generally speaking, class 2 standard is for North American market using, class II is for European market using. Both of them are important standard for safety of the power supply and the user. Here I would like to make a brief introduction for the driver power supply with class 2 standard. The class 2 here refers to the power performance and wiring requirements.

When you find a power supply with a label marked class 2, then it means that it must meet the standards laid out by The National Electric Code. To avoid risk of shock or fire, the wiring and power limitation should meet requirement of this standard.

Wiring of Class 2 power supplies requirements help prevent cracking or melting of the wire. Without these requirements, the power supply can potentially become a dangerous fire hazard. 

Power limitations is another important factor for Class 2 power supply.The requirements are: 1.Less than 5 amps, 2.Less than 100 watts, 3.Less than 60 volts in dry applications 4.30 volts in wet applications.  For example,12 volt 60 watt power supply can meet the power limitation of class 2 standard.

Last but not least, Smarts Electronicsis the Class 2 multi-output 180W 192W 288W 300W 384W led power supply manufacturers. Both dimmable and non-dimmable for your selections. Feel free to contact with us for more details.
