Access Control Power Supply 12V 5A

This 12 V 5 A access-control power supply delivers regulated DC output for electric locks, controllers, readers and push-buttons. It accepts a wide AC input range from 100 V to 260 V, making it suitable for standard mains supplies worldwide. The unit is intended for installers and system integrators building or maintaining door-entry systems. It is not for buyers who need a higher current rating or a different output voltage.

Sustained-load behaviour

Built-in short-circuit protection disconnects the output automatically during a fault, then restores operation once the condition clears. A delay circuit holds the lock energised for up to 15 seconds after the trigger signal ends, preventing premature release under continuous use. Anti-interference filtering keeps the output stable when multiple devices share the same supply. The supply is not designed for loads that exceed its 5 A rating.

12 V 5 A output current

The single specification that determines suitability is the 5 A maximum output current at 12 V DC. This capacity supports two electric locks simultaneously with greater stability than a 3 A alternative. Systems requiring more than 5 A or a voltage other than 12 V will need a different power supply.

Questions about this item

How much heat or noise does the 12V 5A unit produce when running continuously?

The supply uses a metal enclosure that acts as a heat sink and has no fan, so it runs silently; sustained load will warm the case but stays within normal operating limits.

What other components must I already have to make this power supply work with my door?

You need an electric lock (E/M type), an access controller, and an exit push button or RFID reader; the supply provides 12V 5A DC to power them all.

Will the 12V 5A output work reliably with an older 12V 3A lock I want to keep?

Yes — the supply delivers up to 5A at 12V, so a 3A lock draws only what it needs; the built-in short-circuit protection also safeguards legacy devices.
