The Power Supply Unit (PSU) is a critical component in any access control system, converting alternating current (AC) from the mains into stable direct current (DC) at specified voltages (typically 12V or 24V). It provides dedicated power to all connected access control devices, including electric locks, card readers, request-to-exit sensors, and control panels. Many PSUs also feature battery backup capabilities, ensuring system functionality during power outages, and often include reporting features for low battery or AC failure conditions.
