Purpose and Fit

This 12V 5A access control power supply delivers regulated DC power to electric locks, controllers, readers and exit buttons in commercial or residential entry systems. It accepts a wide AC input range from 100V to 260V, making it suitable for standard mains voltages worldwide.

Upgrade Path

The 5A rating supports two locks simultaneously with greater stability than a 3A unit, which is adequate for a single lock. Choose this model when the installation includes multiple locking devices or when cable runs add enough resistance to demand extra current headroom.

Build Integration

The supply connects directly to the lock, access controller, exit push button and RFID or IC reader, reducing wiring back to the controller and lowering its load. Adjustable delay from 0 to 15 seconds sets the lock release time, while built-in short-circuit protection disconnects output automatically during a fault.

Questions about this item

What AC input voltage range does this 12V 5A power supply accept?

The unit operates from 100 V to 260 V AC, covering standard mains supplies worldwide.

How do I wire the lock output and set the release delay?

Connect the lock to the NC or NO terminals, then adjust the onboard timer for 0 to 15 seconds of delay.

When should the internal fuse be checked or replaced?

Inspect the fuse after any short-circuit event; the automatic protection disconnects output until the fault is cleared.
