Power supply for door access control systems that delivers stable 12 VDC power and built‑in lock control to simplify installation and improve system reliability. Key benefits Stable 12 VDC output (5 A) ensures consistent operation of locks, controllers, and video doorbells, reducing false triggers and system resets. Integrated NC/NO lock outputs allow direct control of different electric lock types without separate relay modules. Built‑in protections (overload, overvoltage, short circuit) increase safety and reduce downtime by protecting connected equipment. What it does Provides a reliable DC12V/5A power source for access control components including video doorbells, access controllers, electric door locks, and exit buttons. Acts as the single transformer/power module to power and manage lock outputs for small to medium access control installations. Technical specifications Input: AC 60V–260V, 50–60 Hz Power: 36 W Output: DC 12V / 5A Lock control: Configurable NC / NO outputs Protections: Overload, overvoltage, short circuit, and automatic protection functions Compatibility and performance Compatible with standard video doorbells, access controllers, electric strike locks, magnetic locks (using appropriate lock wiring), and exit buttons requiring 12 VDC. Designed to provide stable voltage under typical access control loads up to 5 A; helps maintain consistent device performance and prolong component life. Installation and practical notes Single‑module solution reduces wiring complexity by combining power conversion and lock control. Suitable for installation in standard access control panels and enclosures; follow local electrical codes when wiring and mounting. Use the NC/NO selection to match the lock type and required failsafe/failsecure behavior. Typical applications Residential or multi‑unit building entry: Powering a video doorbell, access controller, and electric strike for a single entry point. Office or small commercial access point: Centralized power and lock control for one or more door controllers and an exit button. Remote gate or service door: Supplying stable 12 VDC to magnetic or strike locks with built‑in short‑circuit and overload protection to guard against wiring faults. Safety and reliability Automatic protection features minimize risk to connected devices and help ensure continuous operation. Use recommended wiring practices and rated fuses or breakers on the input side per local regulations. Includes Power supply unit with DC12V/5A output and configurable NC/NO lock outputs (no additional accessories included unless specified by the seller). Note: Follow manufacturer installation instructions and local electrical codes. Verify compatibility with specific lock models and access controllers before installation.
