What is the typical voltage range for low voltage systems?

The typical voltage range for low voltage systems is generally defined as 48V DC or lower. Low voltage systems are used in a variety of applications such as telecommunications, alarm systems, and low power electronics. The designation of low voltage usually indicates a safer operating threshold, minimizing the risk of electric shock and making installations simpler and safer.

In the context of the choices provided, other voltages like 120V AC and 240V AC are considered standard power voltages used in residential and commercial electricity supply, which are higher than low voltage. The 12V DC option, while common in certain low power applications like automotive systems and some electronics, does not encompass the broader range that 48V DC includes. Therefore, the range of 48V DC or lower captures a more accurate representation of the typical voltage range for low voltage systems.
