12 V 5 A access-control power supply

The unit delivers a regulated 12 V output at up to 5 A for access-control systems. It accepts AC input from 100 V to 260 V and includes short-circuit protection with automatic recovery. The metal enclosure houses delay circuitry adjustable from 0 to 15 seconds. NC and NO relay outputs allow direct control of various electric locks.

Compatibility check before ordering

Verify that your lock or controller operates on 12 V DC and does not exceed the 5 A rating. Confirm the local mains voltage falls within the 100 V to 260 V range. Ensure the enclosure can be mounted in a dry indoor location with adequate ventilation. Check that wiring for NC/NO contacts and delay setting matches your access controller requirements.

Who this suits and who should look elsewhere

Installers powering one or two electric strikes or magnetic locks from a single supply will find the 5 A capacity stable. The adjustable delay and dual relay outputs simplify wiring for standard access panels. Buyers needing higher current for multiple locks or a different output voltage should look elsewhere. Those requiring outdoor-rated or battery-backed units will need a different product.

Questions about this item

What does the 12V 5A power supply include and what must I buy separately?

The unit supplies 12V DC at up to 5A for electric locks, controllers, exit buttons and RFID readers; locks, controllers, buttons and readers are not included.

Should I choose the 12V 3A or the 12V 5A version for my installation?

Use 12V 3A for a single lock; choose 12V 5A when powering two locks for more stable operation.

What does the 0-15 second delay figure mean in daily use?

The adjustable delay keeps the lock released for up to 15 seconds after a valid credential before it relocks automatically.
