What characterizes an inherently limited Class 2 power source?

An inherently limited Class 2 power source is characterized by built-in current limiting characteristics. This means that the source is designed to restrict the amount of current it can deliver, ensuring that it operates within safe limits to prevent potential hazards such as overheating or electrical fires. Such power sources are typically designed to provide a maximum output that does not exceed certain thresholds, which adds a layer of safety in applications where excessive current could be dangerous.

Inherently limited Class 2 power sources are commonly utilized in low-voltage applications, such as smoke detectors and alarm systems, where safety is paramount. The limiting characteristics help protect against overload situations and ensure that the devices powered by this source do not draw more current than intended, thereby safeguarding both the equipment and the users.

Other options are not characteristic of an inherently limited Class 2 power source: it is specifically designed with current limiting features, does not exceed certain power ratings without protection, and is not typically used in high-power applications due to its design limitations.
