12V 3A Power Supply for Door Locks
This power supply converts standard AC mains voltage to a stable 12 V DC output rated at 3 A. It is designed to run a single electric lock, access controller, exit button or RFID reader in a door access system. The unit accepts an input range of 110 V to 240 V AC and includes automatic protection against short circuits.
Installers powering one lock
The supply suits installations with a single lock where the 3 A rating provides sufficient current. It also fits projects that require selectable normally closed or normally open contacts and an adjustable lock delay of up to 15 seconds. Buyers planning to drive two locks simultaneously from one unit should consider the higher-rated 5 A version instead.
Adjustable 0-15 second lock delay
A built-in delay circuit lets the installer set the lock release time anywhere between 0 and 15 seconds to match site requirements. If a short circuit occurs, the supply temporarily disconnects output or blows its internal fuse to protect connected devices. This single safety and timing feature determines whether the unit matches the access system design.

Questions about this item
How can I confirm the unit is delivering stable 12 V output after wiring it to my lock and controller?
Measure the DC terminals with a multimeter while the lock cycles; a steady reading at the rated voltage shows the supply is operating correctly.
What comes in the box and what must I source separately for a single-lock installation?
The power supply itself is included; you will need to provide the electric lock, access controller, exit button and all low-voltage wiring.
Should I select the 12 V 3 A or 12 V 5 A version for one lock?
For a single lock the 3 A model is sufficient; choose the 5 A version only if you plan to run two locks from the same supply.
