A Class 2 power supply is not explicitly defined in the given passage. However, the passage discusses CLASS II and CLASS III power supplies. CLASS II power supplies typically use two-prong plugs, while CLASS III products rely on safety extra-low voltage (SELV) for protection against electric shock.
CLASS 2 power supplies have no such safety requirements. Understanding the distinctions between CLASS I, II, III, and CLASS 2 power supplies is essential for engineers and manufacturers to ensure compliance with safety standards and create products prioritizing user safety.
In contrast, Class II power supplies may offer sufficient performance for lower power applications but may not match the efficiency of Class I. Class III power supplies, while safe and user-friendly, tend to have limited output capacity and efficiency compared to the other classes.
What is IEC Power Supply Protection Classes ? Class I and Class II Power Supplies 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 protect the power user from dangerous voltages from the input power supply.
