What is a "power supply unit" in an access control system?

A power supply unit in an access control system is essential for ensuring that the entire system receives the correct electrical power necessary for its operation. It converts and regulates incoming electrical supply to meet the voltage and current requirements that the access control components need to function effectively.

This unit typically powers the various elements of the system, such as card readers, electric locks, and control panels. Without a reliable power supply, the components would be inoperable, which would compromise the security measures the access control system is supposed to enforce. Therefore, understanding the role of a power supply unit is crucial for maintaining the functionality and reliability of an access control system.
