What is the maximum power limit for Class 2 sources?

The maximum power limit for Class 2 sources is established to ensure safe operation and prevent hazards such as overheating or electrical shock. Class 2 power sources are designed to deliver a limited amount of power, which makes them less likely to cause serious injury or damage. The standard power limit for these sources is set at 100 Volt-Amperes (VA). This 100 VA limit is significant because it allows devices to operate safely while still providing enough power for various applications without exceeding the safety regulations.

Selecting a value higher than 100 VA would classify the source as a different type, which could involve additional safety requirements and regulations. This framework is designed to protect users and equipment by limiting the potential energy present in the power circuit. Thus, the designation of 100 VA for Class 2 sources encapsulates both safety and functionality within the specified applications.
