Access Control Power Supply

This unit provides a regulated DC 12V 3A output from an AC 110~240V input for access control systems. It powers electric locks, controllers, exit buttons and RFID readers directly. The built-in delay circuit allows lock release times between 0 and 15 seconds. Automatic protection disconnects the output during a short-circuit event.

Replaces Basic Transformer

It replaces a simple transformer by integrating delay control and selectable NC/NO outputs for different lock types. The jump is worth it when the installer needs to reduce wiring back to the access controller and add automatic short-circuit protection. It suits projects that require a single box to drive the lock and peripheral devices.

3A Output Headroom

The 3A DC output comfortably handles one electric lock plus a controller and reader simultaneously. It runs out when multiple high-current locks or additional accessories exceed the 3A rating. The 15-second maximum delay covers standard entry scenarios but cannot support extended hold-open requirements.

Questions about this item

What AC voltage range does this 12V 3A power supply accept for installation?

The unit accepts a standard AC input of 110V to 260V, making it compatible with most mains supplies worldwide.

How do I set the lock delay time on this access control power supply?

Adjust the built-in delay control circuit to the desired setting between 0 and 15 seconds for the electric lock release timing.

What protective maintenance does the internal fuse require after a short-circuit event?

The automatic protection disconnects power during a short circuit; the fuse acts as an auto insurance line that must be replaced after it blows.
