Currently, external power supplies that meet the definition of a “Class A” external power supply are required to meet specific energy conservation standards articulated at 10 CFR 430.32(w)(1)(i).
Class I power supplies have an earth-ground connection, whereas a Class II product does not. A Class I product must have two levels of protection between live (primary) parts and the end-user
PSL low-profile and PSC compact are small frame, NEC Class 2 power supplies designed to reduce panel footprint without compromising electrical fire and shock prevention.
A partial list of compatible products and the number of units that may be powered by each power supply are listed below. Capacity is based on the VA rating of each product to be used with the power supply.
The International Electrotechnical Commission (IEC) defines three safety levels for power supplies: Class I, Class II and Class III. These three levels are used to identify different ways to
