In this guide, you''ll learn the differences between Class 2 and Class II power supply, eliminating confusion and protecting users.
The power supply industry uses Class 2 and Class II terminology to refer to two very different types of power supplies. The industry has been using these terms for decades now.
In summary, ceramic capacitors are widely used in today''s electronic circuits. According to the EIA, these capacitors fall into three classes: Class I, Class II, and Class III.
Class I power supplies are designed with safety mechanisms that include grounding for protection against electrical shock. These supplies typically operate at higher voltages and currents, which makes them suitable for demanding applications such as industrial machinery and medical devices.
Class 2 power supplies offer a distinct approach to safety compared to Class 1. They are designed with inherent safety features that minimize the risk of electrical shock, even without a protective earth connection.

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.
CLASS 2 power supplies have no such requirements. In conclusion, 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.
Many mobile phone chargers, laptop power supplies, and other household appliances feature Class II input to ensure the safety of people in their homes. Power supplies featuring Class II input display “ Class II” or “ Double Insulated” or the Concentric Square Symbol on the safety label.
Class 1 power supplies, as defined by safety standards like UL 62368 and IEC 62368, are designed with a protective earth (ground) connection. This connection, typically implemented through a three-prong plug, provides a low-impedance path for fault currents to flow in the event of a malfunction or component failure.
