YINGHUA 12V 5A High End Supplier Adapter Covertor 100~260V Door Lock Power Supply

12V 5A Access Control Power Supply

This 12V 5A power supply delivers stable DC output for access-control systems, supporting electric locks, controllers, exit buttons and RFID readers. It accepts a wide AC input range from 100 to 260 volts, making it suitable for global installations. Built-in short-circuit protection and a delay circuit adjustable from 0 to 15 seconds add reliability for daily entry management.

Installers running one or two locks

The 5A rating provides extra headroom when powering two locks from a single unit, while a 3A model would suffice for a single lock. NC and NO outputs allow compatibility with various lock types and reduce wiring complexity at the controller. Buyers needing only one lock or a lower current budget should consider the 3A alternative instead.

Adjustable 0-15 second lock delay

The on-board delay circuit lets you set the lock release time anywhere between 0 and 15 seconds to match specific entry requirements. This single setting determines how long the door remains unlocked after activation and is the key specification to verify against your access controller's timing needs.
